Throughout the process of learning how

0:01

to mix music, many people hit a wall

0:03

where they know something's wrong, but

0:06

they can't quite [music] name it.

0:07

Whether the kick is fighting the bass or

0:09

the vocal is just sitting on top of

0:10

everything instead of being inside the

0:12

mix as a cohesive piece. Whatever it is,

0:15

you end up turning the same knobs back

0:17

and forth for about an hour, and somehow

0:19

[music] you end up worse than where you

0:21

started. If you've done that, leave a

0:23

comment below. I definitely have done

0:26

that, and I'm sure we're not alone. It's

0:28

not that you're doing something wrong.

0:30

What's missing [music] is the connection

0:32

between what you're hearing and what you

0:34

can actually do about it using the tools

0:36

available.

0:38

That connection

0:39

>> [music]

0:39

>> is what a good education gives you, but

0:42

it's harder to find good education

0:43

>> [music]

0:44

>> than it should be. A lot of mixing

0:45

videos on YouTube, my own included, tend

0:48

to teach you how tools work,

0:50

>> [music]

0:50

>> which is helpful information, but it's

0:53

less common to find videos that tell

0:55

[music] you how to translate what you're

0:56

hearing into adjustments on those tools.

1:00

Today, I want to walk you through four

1:02

concepts, one for each of the primary

1:05

tools you're probably already using: EQ,

1:07

compression, reverb, and delay. Each one

1:10

is a specific idea that gave me a

1:13

framework for when to choose the tool

1:15

and what to listen for once the tool

1:17

[music] is in the signal chain. These

1:19

come from the mixing and ear training

1:21

program at Audio University, which is

1:23

taught by myself and [music] Gabe

1:25

Herman, who's been teaching audio

1:27

engineering and mixing professionally

1:29

for over 20 years. I'm going to pull

1:31

some clips from the course so you can

1:33

hear Gabe explain these ideas directly,

1:36

>> [music]

1:36

>> and if any of this lands for you, the

1:38

program is linked in the show notes

1:40

below.

1:44

Let's start with EQ because I think it's

1:46

where most people spend most of their

1:48

time, and it's also where most people

1:50

are working much harder than they really

1:52

need to. The typical approach goes

1:54

something like this. You hear something

1:56

off in the mix, you open an EQ plugin,

1:59

you sweep a boost around until you find

2:01

a frequency that sounds bad, and then

2:04

you cut it. And the logic here makes

2:05

sense, and it is really a good tool and

2:09

a good technique that I still use at

2:11

times.

2:12

The problem is that it can lead to more

2:14

problems than it solves. If you apply a

2:17

big boost while you sweep through the

2:18

frequency spectrum, you can make almost

2:21

anything sound terrible at almost any

2:24

frequency, which means you end up

2:26

cutting things that weren't actually

2:28

problems in the first place. There's a

2:30

faster way to get your bearings with EQ

2:32

that one of my teachers taught me.

2:34

Certain frequencies correspond to vowel

2:36

sounds. Your mouth is a resonant cavity,

2:39

and when you shape it to say a vowel

2:41

sound, you're resonating at a specific

2:43

frequency. Once you make that connection

2:45

between what frequency corresponds to

2:48

what vowel sound, you have a reference

2:50

point every time you open an EQ.

2:53

Around 250 hertz, you get the "oo" sound

2:56

like the word boot.

3:02

Move up to 500 hertz, and it shifts to

3:05

an "o" sound like boat.

3:10

At 1 kilohertz, you're in "ah" territory

3:14

like the word father.

3:20

2 kilohertz is more like "a" as in face.

3:27

And 4 kilohertz is an "e" sound like the

3:30

word meet.

3:36

Above [snorts] 4 kilohertz, you start to

3:38

get into the sibilance range. 8

3:40

kilohertz gives you a clean "s" sound.

3:43

Higher than that, it gets sharper,

3:45

almost like an "s" mixed with a "t" at

3:48

16 kilohertz.

3:49

Below 250 hertz, you can focus on the

3:52

physical sensation of the sound in the

3:54

body. 125 hertz, you tend to feel in

3:57

your chest, and 63 hertz, you feel

4:00

lower, especially when you're listening

4:02

through full-range speakers or a system

4:04

with subwoofers.

4:06

What this gives you is a way to connect

4:08

what you're hearing to where you need to

4:10

go on an EQ. A vocal that sounds boxy

4:13

might have too much energy around 500

4:16

hertz or 1 kilohertz, somewhere between

4:19

"o" and "ah".

4:21

A mix that sounds harsh usually is a

4:24

buildup of energy sitting between 2

4:26

kilohertz and 4 kilohertz, between "a"

4:30

and "e".

4:31

I'd encourage you to download the free

4:33

ear training guide linked below this

4:35

video for a quick reference for each of

4:37

these reference points I've just shared

4:39

with you. You can also download it at

4:40

4:44

This was a huge revelation for me when I

4:46

learned it, and even if many engineers

4:49

don't use this exact method, they

4:51

probably have some tricks of their own,

4:53

reference points for what they're

4:55

hearing.

4:56

Here's Gabe describing how he approaches

4:58

an electric guitar in one of the mix

5:01

sessions within our course. This guitar

5:03

really speaks from kind of the back of

5:06

the mouth. [music]

5:08

It's got like an

5:11

kind of [music]

5:12

vibe to it, and I use my mouth and I use

5:15

the sounds in my [music] mouth to EQ all

5:17

the time because it helps to kind of

5:19

place things in my body, and then I can

5:22

internalize them better.

5:23

>> That instinct, translating what you hear

5:26

into something your body already knows

5:27

and understands, is a foundational

5:30

element of ear training that actually

5:31

sticks with you. The key is repetition.

5:34

You hear it, identify it, apply a

5:36

change, and check the result. And over

5:39

time, you stop guessing and start using

5:41

EQ with a goal in mind.

5:44

Okay, compression. Most people learn to

5:46

think of a compressor as a dynamics

5:48

tool. It catches loud moments and pulls

5:51

them back, and that's accurate, but it

5:54

misses something else that's important

5:56

about what compressors actually do to

5:58

the sound. And after watching Gabe teach

6:01

this, it really started to click for me.

6:04

Here's how Gabe puts it in the course.

6:06

Compressors make square waves.

6:08

They are uh

6:10

really not generating the the effect

6:12

that most people associate with dynamic

6:14

range control. While they do control

6:16

dynamics, it's the interaction of their

6:19

dynamic range control

6:21

um devices and and components that

6:25

generate um harmonic saturation and

6:27

harmonic distortion

6:29

in a way that is different than just

6:31

dynamic range control. And so we need to

6:33

be able to think about dynamic range

6:35

control separate from harmonic

6:36

distortion, and you might get further

6:39

learning how to use a compressor not

6:40

just by hearing how the dynamics of the

6:42

signal change under compression, but at

6:44

the same time learning to hear what the

6:47

harmonic qualities are of too much

6:49

compression

6:50

um or poorly timed compression, etc.

6:54

You should focus on the intent. Why do

6:56

we use a compressor? What changes do we

6:59

want to see in our sound? What should

7:01

stay the same?

7:03

Think of distressers uh uh think of

7:05

compressors as distortion boxes and pair

7:07

them with complementary source material.

7:09

So, if you have um a uh

7:13

a very fast transient in a snare drum

7:15

signal, say you've recorded your snare

7:17

with an API uh 512 mic pre with an op

7:21

op-amp circuit, um those do a great job

7:24

of preserving transients. It may be ad-

7:27

uh advantageous for you to uh then use a

7:30

compressor paired with that signal

7:31

that's able to handle very fast

7:33

transients.

7:34

Um so, think about the um the the tool

7:37

as being um the way that tool is

7:40

designed to be applied to a specific

7:42

type of sound, and that might help you

7:44

develop uh a better strategy, and we

7:46

will discuss strategies as another part

7:48

in the series.

7:50

Lastly, I want you to remember, and this

7:52

is the most important thing, and you'll

7:53

maybe get tired of me hammering on them

7:55

so hard throughout this, but compressors

7:57

are not intelligent. You are

8:00

intelligent. Compressors as distortion

8:03

devices, not just as dynamic

8:05

controllers. Every time a compressor

8:07

acts on a signal, it's not just turning

8:09

down the loud parts, it's changing the

8:12

shape of the waveform, and that change

8:14

produces harmonic distortion. The

8:16

character of that distortion comes

8:18

directly from your attack and release

8:21

settings. A fast attack means the

8:23

compressor clamps down quickly and

8:25

starts reshaping the waveform almost

8:27

immediately. And a fast release means it

8:30

recovers very quickly. The more

8:31

aggressively the waveform gets reshaped,

8:34

the more harmonic distortion is

8:36

produced, and the more the character of

8:38

the sound changes. Slower settings mean

8:41

less reshaping, less distortion, and a

8:43

cleaner sound overall. That's a big part

8:46

of why two compressors with different

8:48

time constants can sound completely

8:50

different at the same ratio and

8:52

threshold. The timing settings aren't

8:55

just controlling dynamics, they're also

8:57

controlling character.

8:59

Here's Gabe working on a kick drum using

9:01

compression specifically to shape the

9:04

tone.

9:05

I want to talk about setting attack and

9:07

release times and how I might use a

9:09

compressor to shape the tone of a kick

9:10

drum.

9:11

In this session, I've got just one track

9:14

we're going to be listening to, which is

9:15

the kick in mic. Let's give it a listen.

9:28

In our previous session on EQ, I

9:30

discussed how I used this frequency

9:32

curve to enhance the sound of the kick

9:34

drum. I'm going to bypass that so we can

9:36

hear the difference of the signal

9:38

without the EQ versus with the EQ.

9:42

Without it.

9:47

With it.

9:52

What I'd like to point out is that we

9:54

used an EQ in in previous session to

9:56

enhance the low frequency content and to

9:58

make the uh articulation of the kick

10:00

drum a little stronger while reducing

10:02

some of the frequencies that were

10:03

shadowing the upper mid-range um closer

10:07

to around 200 hertz. We call this the

10:09

mud range.

10:11

Um today when we install a compressor

10:14

behind this signal we're going to be

10:16

changing the envelope and introducing

10:18

harmonic distortion to that signal.

10:21

When I think about what I want to change

10:23

about this signal, I have to be very

10:24

careful.

10:26

If I were looking at the frequency

10:27

responses drawn on the waveforms of our

10:30

edit window, you'll see very fast

10:32

transients followed by some pretty quiet

10:35

resonances.

10:37

Uh of course, this is what the waveform

10:38

looks like before the EQ, not after.

10:42

If I wanted to do that, if I wanted to

10:44

see what it looks like, I would have to

10:46

commit the audio up to this level

10:49

which I'm going to do right now.

11:01

As I do this, what I'm going to see is a

11:04

change in the waveform that will

11:05

actually represent what's different now

11:08

that I have

11:10

um made the uh EQ rendered.

11:14

What we see now is that before the body

11:17

of the kick drum, which was a little bit

11:19

weak, has been made a little bit

11:20

stronger.

11:21

But we still have these very strong

11:23

transients

11:24

followed by some relatively quiet

11:27

resonance of the kick drum.

11:29

What I'd like to do is use a compressor

11:31

to tame the transients and make these

11:34

sections here after the transient a

11:36

little bit louder.

11:38

If I use my cursor tool to select just

11:40

this amount of time that is my transient

11:42

for this kick drum hit I can look up and

11:45

see that it's about 1 millisecond of

11:47

time here from start to end.

11:50

A difference of .096

11:52

uh milliseconds.

11:55

Or a tenth of a millisecond I should

11:57

say.

11:58

So when I set up my compressor, what I

12:00

want to be very careful of

12:02

is that I'm not making the time too

12:04

long. If I make the attack time too long

12:07

I'll uh end up setting up a compressor

12:09

that's too slow to be able to react to

12:11

the signal.

12:12

And that means I'll end up compressing

12:14

what's happening on the back end of my

12:16

signal, this later part which is the

12:18

body

12:19

and the resonance in the decay of the

12:21

tone of the of the envelope of the

12:22

signal.

12:24

That wouldn't be good at all because

12:26

what I really want to do is squash the

12:27

transient, not the body. So I need to

12:30

keep my attack times pretty quick.

12:33

Lucky for me this stock compressor that

12:34

comes with Pro Tools is very quick. I'm

12:37

going to set the attack time to 10

12:38

picoseconds. That's way fast enough to

12:41

be able to uh uh

12:42

uh get out in front of this transient.

12:46

At the same time I want to make sure

12:47

that my release time is also very fast

12:49

because I want the compressor to be able

12:51

to stop compressing relatively quick.

12:54

I need to reduce the volume here. If I

12:57

go with something strong like 6 to 1

12:59

compression that's going to create many

13:02

more harmonic uh

13:04

uh uh uh

13:05

auto order harmonic uh elements in my

13:07

signal than I think I really want.

13:10

I like the way this sounds right now.

13:11

It's warm, it's punchy, it's thick. If I

13:14

start introducing too many auto order

13:15

harmonics to the signal, it's going to

13:17

change the timbre of the signal to be

13:20

more crunchy, more gritty, maybe a

13:22

little bit more aggressive, which is

13:23

fine for some music, not in this case.

13:26

So I'm going to set my attack time to be

13:28

very fast, my release time to be very

13:30

very fast. I'm going to set my ratio to

13:32

something a little bit more prudent, say

13:35

2 to 1.

13:39

I'm going to be very judicious with my

13:40

threshold. I want to make sure that the

13:42

signal is just barely coming up over the

13:44

threshold. Remember the further down I

13:47

bring the threshold, the more of the

13:48

signal will be squared off.

13:50

So I really don't want to be too

13:52

aggressive with this or else I might end

13:53

up having it sound a little bit crunchy.

13:56

Just to demonstrate what that sounds

13:57

like though, I am going to show you what

13:59

it sounds like when we go a little too

14:00

far.

14:01

But let's start with just trying to find

14:03

a good starting point. So I'm going to

14:06

bypass

14:07

uh this

14:08

compressor. I'm going to select a little

14:10

bit of uh signal here and we're going to

14:12

loop it.

14:16

>> [music]

14:19

>> Now we have our

14:21

our kick drum soloed.

14:23

I'm looking at the meter and I'm seeing

14:25

that the threshold the way it's set

14:26

right now

14:27

the needle just basically pops right

14:30

over the edge of this threshold line

14:33

just when the transients hit.

14:36

I can also see that it rebounds back

14:37

pretty fast.

14:39

I'm going to up my threshold just a

14:40

little bit more.

14:45

And I'm going to slowly bring it down up

14:46

until I start to see

14:49

some orange flashes that come all the

14:51

way down to close to about -3.

14:55

More than that and I'm going to start to

14:56

really be introducing a lot of harmonic

14:58

distortion.

15:00

The other thing I need to be careful of

15:01

is that there are some hits that are a

15:02

little bit stronger than others. There's

15:04

no consistency here.

15:06

So maybe my goal is to make all the

15:08

transients consistent

15:11

and then work from there.

15:12

So I'll bring down my threshold

15:33

to where all of my transients are

15:34

basically getting hit a little bit.

15:36

This will make sure that all of these

15:37

tops are getting brought down.

15:41

Now

15:42

I'm going to put in uh take the bypass

15:44

out and we'll hear what that sounds

15:46

like.

15:49

Ah instantly

15:51

we can hear that squaring off of that

15:52

waveform, that harmonic distortion.

15:57

>> [music]

16:02

>> Too much.

16:03

I'm going to give back a little bit.

16:06

>> [music]

16:17

>> That's a little better but I can still

16:19

hear some crackle. Now I'll start to

16:21

slope slow down the release time a

16:22

little bit.

16:32

Now I should be able to back my

16:33

threshold in a little bit more without

16:34

hearing as much

16:36

of that distortion because my compressor

16:38

isn't acting as strong. It's not

16:39

creating a sharp a square wave.

16:52

That sounds better. Now if I bypass it

16:58

and with the compressor in

17:04

it's quieter. The transients aren't as

17:06

loud and if we listen very carefully, we

17:08

might actually even be able to start to

17:10

hear some of those harmonics creeping

17:11

into the tone of the signal.

17:13

I'm going to make this a little bit

17:14

louder though. I'm going to use my

17:15

makeup gain now

17:17

to make the overall signal louder.

17:20

That should help to bring out these

17:21

resonance that I'm trying to bring out

17:23

in my tone. But as I do, you'll also

17:25

start to hear the harmonic distortion

17:27

come out from the compressor.

17:31

>> [music]

17:37

[music]

17:40

>> Without the compression

17:45

with it.

17:52

In my description earlier

17:54

uh in my presentation, I discussed that

17:56

we should think about compressors as

17:57

time-based processors.

17:59

What I think we can hear

18:07

to hearing a sound that's actually quite

18:08

long in its resonance. It takes a lot

18:11

longer for the sound to go away.

18:13

It's because I'm compressing the signal

18:15

and I'm bringing up I'm compressing the

18:17

transients and I'm bringing up all the

18:18

noise floor stuff that's happening

18:20

later.

18:21

So what's happening is you could think

18:23

of it as as as controlling dynamic

18:24

range, but what I'm really doing is

18:25

making the sound last longer

18:28

which is a time domain process, right?

18:30

I'm making the sound last longer,

18:31

therefore we're going to hear it a

18:32

little bit clearer. It's going to sound

18:34

louder to our ear.

18:37

The other thing is I've introduced a lot

18:38

of harmonic distortion and we can hear

18:40

that the the kick drum has gone from

18:42

being kind of low and punchy and uh

18:44

ticky to being kind of from from from uh

18:49

loose and flappy.

18:51

These are bad descriptive words but

18:53

they're the best we can do when we're

18:54

talking about subjective uh qualitative

18:57

uh assessment here. Um I can measure the

18:59

harmonics but I can describe it as being

19:01

different in some sort of way that's not

19:03

just the harmonics but the quality of

19:06

the sound.

19:08

So we have to figure out a way to

19:11

balance the uh uh uh

19:14

uh balance the the the issues here. We

19:16

we have On the one hand I'm I'm

19:17

succeeding at compressing and and

19:20

suppressing the transient of the signal.

19:22

On the other hand

19:24

as I'm doing that I'm also bringing up

19:26

the harmonics in the back end of the

19:27

signal and that's not very good.

19:29

So we have to find a way to kind of come

19:32

to terms here. So I'm going to uh

19:35

uh introduce a compromise.

19:37

Perhaps what I want here is not as much

19:39

compression.

19:41

Maybe I can take 1 and 1/2

19:45

to 1

19:46

instead of 2 to 1.

19:49

That should help. I can also soften my

19:51

knee.

19:52

By softening the knee, I'm making it so

19:54

that I'm not squaring off the

19:55

compressor. The com- The compressor is

19:57

not squaring off the waveform quite as

19:58

aggressively. It's going to curve around

20:02

that compression point, which should

20:04

help to preserve some of those

20:07

transients that had that sine wave type

20:11

element to them, so that they're not

20:13

suddenly becoming flat mesas.

20:16

Um that should also help. So, let's try

20:18

introducing some knee and we backed off

20:20

the ratio a little bit.

20:25

>> [music]

20:31

>> Uh that's much better.

20:34

>> [music]

20:35

>> Without the compression.

20:40

With it.

20:43

>> [music]

20:45

>> Here we're hearing a little bit less of

20:47

an aggressive harmonic tonality to the

20:49

compression. If compression adds

20:51

harmonic distortion every time it acts

20:54

on a signal, then using it to fix uneven

20:57

dynamics means adding coloration to

21:00

every moment you're trying to correct.

21:02

The compressor doesn't know it's dealing

21:04

with a word that got swallowed or a

21:06

guitar phrase that was played softer. It

21:08

reacts to level and it reacts the same

21:11

way every single time. You're smarter

21:14

than a compressor, though. For the

21:15

dynamic problems that are really about

21:18

performance, a phrase that's too quiet

21:20

or a syllable that got lost, you might

21:23

be better off going in manually. That

21:24

could mean adjusting the clip or region

21:26

gain, which happens before the signal

21:29

hits the compressor. That way, you

21:31

smooth out the performance before the

21:33

compressor even sees the signal. Then

21:36

the compressor can focus on what it's

21:38

actually there for, adding texture and

21:40

character, if you want texture and

21:43

character.

21:44

Here's how Gabe explains it. You should

21:46

try to get 90% of the way there with

21:49

your tracking technique, your clip gain

21:52

automation or with volume automation,

21:54

and then use the last 10% of that

21:56

control. Um maybe that's done with a

21:59

compressor.

22:00

Okay? And And this is the number one

22:02

trick that once I show my students how

22:04

this works, like they're suddenly

22:06

compression just becomes a lot more

22:07

intuitive.

22:09

It's funny. There's things about dynamic

22:11

range that have to do with performance

22:14

and not um harmonic distortion. So, if

22:17

you want to control the dynamics of a

22:19

signal,

22:20

you shouldn't reach for compressor to do

22:22

that.

22:23

Reach for um if you're in the tracking

22:25

stage,

22:27

repositioning the microphone. Maybe it's

22:29

pulling the microphone further away, so

22:31

that you don't have quite as much of a

22:32

dynamic range between loud bits and

22:34

smaller bits, because everything's less

22:35

focused. That can still sound really

22:37

great. In fact, pulling the mic back um

22:41

might help you

22:42

um be more successful at using

22:44

compression while tracking, because the

22:46

compressor isn't trying to do the heavy

22:48

lifting of pulling the levels down when

22:49

it goes significantly above the

22:51

threshold, but most of that's just been

22:53

taken care of naturally by the uh the

22:56

inverse square law and the fact that

22:57

you're pulling the microphone away,

22:59

you're pulling the mic away, so you get

23:01

less proximity effect in the vocal. Um

23:03

the dynamic range of the vocal will get

23:06

naturally more even. And then when the

23:08

compressor is activated, it's working on

23:10

a much smaller percentage of the signal

23:12

than if it's right up in the mouth of

23:14

the performer, where it's having to do

23:16

an awful lot. You're just going to get a

23:17

lot of harmonic distortion from that,

23:19

not necessarily dynamic range control

23:21

that you might want in the presentation

23:23

of a performance.

23:25

So, um

23:26

my suggestion is to try to get

23:30

the dynamic range part of your signal

23:33

under control using automation and be

23:36

intelligent about which syllables you

23:38

want to emphasize. Put a little flourish

23:40

on the last line of every vocal. Um

23:43

uh think about words like uh and the and

23:46

from and the small syllables that

23:47

sometimes get lost. Try to boost those

23:50

up with gain control, um gain

23:53

automation, so that they're more

23:55

present, because a compressor isn't

23:57

going to be listening to the lyrics and

23:58

deciding, I didn't understand what they

24:00

said right there. I should have

24:01

compressed that better.

24:03

Compressors are not smart. They do not

24:05

take intelligent uh

24:06

intelligence into into consideration

24:08

when they make their changes. They act

24:10

aggressively and consistently, and they

24:13

will not bring humanity into your

24:15

tracks.

24:16

The goal isn't to avoid compressors.

24:19

It's to use them for what they do well

24:21

and stop asking them to solve problems

24:24

they can't fully understand.

24:28

You're probably already familiar with

24:30

the standard use of reverb in a mix. You

24:32

put something in a space to make it feel

24:34

more real or you add a shared room to a

24:37

mix, so everything feels like it belongs

24:39

together. Both of those are useful, but

24:42

when I watched Gabe explain another

24:43

situation where he uses reverb, it took

24:46

me by surprise.

24:47

He thinks of reverb in some cases as an

24:50

EQ tool.

24:51

Not just a metaphor for EQ, but as an

24:54

actual way to control the tonal balance

24:56

of the full sound.

24:58

When a room resonates, it reinforces

25:00

certain frequencies and lets others

25:02

decay faster. So, by choosing the type

25:05

of reverb, shaping its frequency content

25:07

and controlling its decay time, you can

25:10

augment the tonal character of the

25:12

instrument in a way that feels more

25:14

tonal than spatial. Here's Gabe working

25:17

on an acoustic guitar that's been EQ'd

25:20

and compressed and is sitting reasonably

25:22

well in the mix, but still feeling a bit

25:24

pointed and edgy.

25:26

He goes to reverb in this case.

25:29

People would think of reverb as being

25:30

spatial, but I'm actually going to use

25:31

this to create timbre. Make the the body

25:34

of the guitar feel a little bit more

25:36

mellow. As I'm listening to this, it

25:38

just feels like the guitar is very kind

25:39

of pointy and edgy. So, what I've done

25:43

here is I've created a an aux return and

25:46

a send

25:47

that's called a GT verb and I'm going to

25:49

send this acoustic guitar to this

25:52

return.

25:53

And on this return, I'm going to insert

25:55

a reverb and I don't want anything too

25:58

special. It doesn't have to be something

25:59

fantastical. In this case, I'm using

26:01

Dverb.

26:03

I'm going to turn the gain reduction all

26:05

the way off, so that it's not pulling

26:06

anything out of there and I'm going to

26:08

set the room parameter to small.

26:10

And I really don't want much here, maybe

26:12

about 178 milliseconds.

26:14

That's all I really need to do. And then

26:17

I want to pull the high frequencies down

26:19

to maybe oh, I don't know, 1.6k.

26:24

So, I'm going to put the fader up here.

26:27

Let's hear what this sounds like. I'm

26:28

just going to solo the acoustic guitar

26:30

and we'll see what this reverb sounds

26:32

like.

26:35

>> [music]

26:38

>> If I mute the reverb,

26:45

that's pretty cool.

26:46

It gives it a room. It gives it a space.

26:48

It definitely makes it feel more stereo.

26:50

And I'm starting to get into the

26:51

direction of it sounding warmer, but I

26:53

haven't really gotten there. So, I'm

26:55

going to go into like my EQ here after

26:57

this reverb and I'm just going to make a

26:59

bump at around 200 hertz. What I'm also

27:02

going to do, so that it doesn't get in

27:03

the way of the bass, is I'm going to

27:04

pre-delay this signal maybe about 10

27:07

milliseconds or so. And I'll stop at 12.

27:10

That seems That seems feasible. And I'm

27:13

probably going to want to de-emphasize

27:15

the high frequencies as much as I can.

27:17

So, I might just throw in a a nice

27:18

gentle shelf here

27:20

to further that along. So, I'm really

27:22

tilting the the tonality of this and

27:25

this this hopefully it makes the room

27:27

reflect the low harmonics that are

27:29

bouncing around inside the reverb

27:31

program. That's going to make the guitar

27:32

feel thicker without adding low

27:34

frequencies via EQ into the sound

27:37

directly.

27:39

>> [music]

27:43

>> And I feel a little space between where

27:44

the reverb starts and where the guitar

27:46

ends.

27:52

So, you can hear how the guitar is

27:53

starting [music] to take on that darker

27:54

tone.

27:55

Now, I'm going to do one more thing. I'm

27:57

going to compress the reverb. What we're

27:59

going to try to

28:00

achieve is take all of the fast-acting

28:03

stuff that's in there and kind of pull

28:05

it out and let it release really slow.

28:08

We're going to set the ratio of

28:10

compression to maybe 5 6 to 1 and a

28:13

really soft knee

28:15

like this. And I'm just going to pull

28:16

back the threshold, so we're burying the

28:18

reverb kind of in constant compression.

28:27

Then I'm going to use the output gain to

28:28

bring it back up in my mix.

28:43

And you'll feel [music] that instantly

28:44

my guitar sounds and feels warmer, like

28:47

a warmer bodied instrument.

28:49

If I took this out, [music]

28:54

not only do we lose the space, but you

28:56

can sense that [music] the low harmonics

28:57

just kind of disappear out of it.

29:01

The guitar gets warmer and thicker

29:03

without any change to the dry signal

29:05

itself. He's not EQ'ing the guitar. He's

29:08

EQ'ing the room and what it gives back.

29:11

The same principle applies across

29:13

different instruments. Here's Gabe again

29:15

on a snare drum, deciding he wants the

29:17

snare to sound thicker and fuller.

29:21

>> [music]

29:30

>> Okay, now just a short reverb.

29:46

You can almost hear how it's giving it

29:47

of a flamy feel to it.

29:49

And again, this is just the dry snare by

29:51

itself.

30:01

>> [music]

30:02

>> Now with our processing.

30:07

>> [music]

30:12

[music]

30:17

>> So hopefully you can hear that there's a

30:18

change not just in the presentation of

30:20

the stereo image or the space around the

30:22

snare, but also a temporal shift in the

30:24

snare.

30:25

I could have made the snare feel thicker

30:26

with EQ,

30:28

but the room can do a lot of that work

30:29

for me as well. And rather than try to

30:31

make that individual track uh thicker or

30:35

uh try to push more low frequencies into

30:37

say a compressor which might react

30:38

negatively to it, instead I'll just do

30:40

some parallel processing in the reverb

30:42

and try to get the reverb to add

30:44

harmonics to my dry signal and hopefully

30:46

make the snare uh sound more full and

30:48

lush.

30:49

Different instrument, same idea.

30:52

Once you start thinking about the reverb

30:54

return as something you can shape

30:55

tonally,

30:57

the way you use reverb will change.

31:00

The central idea Gabe comes back to

31:02

throughout the delay section of the

31:03

course is that time and space are the

31:06

same thing. Delay is how we perceive

31:09

distance. When a sound arrives at your

31:11

left ear slightly before it arrives at

31:13

your right ear, your brain doesn't hear

31:15

two different sounds, it hears one sound

31:18

coming from the left side. And that tiny

31:20

timing difference is how you locate

31:22

things in the world around you. And

31:24

you've been doing it your whole life

31:26

whether you thought about it that way or

31:27

not. Think about how you judge distance

31:29

with your eyes.

31:31

Close one eye and you lose depth

31:32

perception.

31:34

The brain needs two slightly different

31:36

views of the same thing to build a 3D

31:39

picture. And hearing works in a similar

31:42

way.

31:43

Delay is one of the most important tools

31:45

we have for creating dimension and

31:47

depth.

31:48

What makes this practical is

31:50

understanding that different amounts of

31:52

delay do completely different things.

31:55

Gabe organizes them into three time

31:57

windows. The first is the binaural

31:59

window from roughly 1 to 10

32:02

milliseconds. In this range, your brain

32:04

doesn't separate two instances of the

32:06

same sound into two distinct events. It

32:10

sums them together and reads the timing

32:12

as a localization cue. A few

32:14

milliseconds of delay on the right side,

32:16

for example, makes the whole thing feel

32:19

like it's coming from the left with no

32:21

panning required. Some engineers use

32:23

this concept called the Haas effect to

32:26

push things wider than the physical

32:28

speaker boundaries. The catch is mono

32:30

compatibility though. When you sum a

32:32

binaural delay to mono, the two versions

32:35

of the signal interfere with each other.

32:38

And what might have sounded huge in

32:40

stereo sounds phasey in mono. So it's

32:43

always worth checking your mix in mono

32:46

before committing. The second window is

32:48

early reflections from about 15 to 35

32:51

milliseconds. This is where delay stops

32:53

being a positioning tool and starts

32:56

being an acoustic tool. At 15

32:58

milliseconds, the brain has just enough

33:00

processing time to register the delayed

33:03

signal as something separate from the

33:05

original. And done intentionally, it can

33:08

register to the listener as a reflection

33:10

of the nearby wall. A helpful guideline

33:13

is that 1 foot of distance equals

33:15

roughly 1 millisecond of delay. So 15

33:19

milliseconds implies a 15-foot path.

33:22

That means delay can be used to define

33:24

the size of the space you're trying to

33:26

create within your mix. You push it

33:29

higher in this range and the implied

33:31

space gets larger. This is how you make

33:33

a dry recording feel like it was

33:35

captured somewhere. And the concept can

33:38

also be implemented using the pre-delay

33:40

setting that you might find in a reverb

33:43

plugin. The third window is late

33:45

reflections from 35 to 60 milliseconds.

33:49

This range adds a deeper sense of room,

33:51

less about where you are and more about

33:54

the character of the space itself. The

33:57

back wall, the texture of the surfaces,

34:00

mono compatibility is less of a problem

34:02

here because the signals have enough

34:05

time between them that they're not

34:06

fighting each other as much. And the

34:09

level between the direct and indirect

34:12

delays tends to be wider and that also

34:15

results in less interference. Beyond 60

34:18

seconds, the brain stops reading the

34:20

second sound as connected to the first.

34:23

It becomes its own event. That's the

34:25

territory of rhythmic echoes and

34:27

slapback creative effects rather than

34:30

acoustic simulation. When you understand

34:32

how the brain interprets different delay

34:34

times,

34:36

you get a sense for what's possible with

34:37

delay. And the next time you want to add

34:40

dimensionality or special effects to a

34:43

mix, you can get close to the settings

34:45

you need without digging through

34:47

presets. So those are the four. EQ

34:50

through the lens of vowel sounds so you

34:51

have a reference every time you open an

34:53

EQ. Compression as something that shapes

34:55

the tone of a signal just as much as the

34:58

dynamics with clip gain handling the

35:01

outliers in the performance before the

35:03

signal reaches the compressor. Reverb as

35:06

a tonal tool, not just a spatial tool.

35:08

And delay as a set of time zones, each

35:12

one producing a different effect on how

35:14

the listener experiences the space

35:16

around the sound. There's a point Gabe

35:18

makes at the end of the course that I

35:20

don't think enough of us focus on while

35:22

we're mixing. It's one skill to use

35:25

compression and EQ to make individual

35:27

instruments sound good.

35:29

It's a different skill entirely to use

35:31

those same tools to make instruments

35:34

work together. So everything has its own

35:37

space and so that the whole thing feels

35:40

like one cohesive sound.

35:42

That second skill is what the course is

35:45

actually building toward. Information

35:47

about mixing or anything for that matter

35:50

isn't hard to come by anymore.

35:52

And that's exciting.

35:54

But the challenge is still to build a

35:56

skill that will actually stick with you.

35:59

And that takes structured practice,

36:00

feedback on your work, and time spent in

36:03

the material with other people working

36:06

through the same things. The Audio

36:07

University membership is built around

36:09

that exactly. The courses are taught by

36:12

myself, Gabe Herman, and other guest

36:14

instructors with decades of experience

36:16

mixing and teaching. And beyond the

36:19

courses, both Gabe and I are active in

36:22

the membership. So you can leave

36:23

comments directly on the lessons or ask

36:26

questions when something doesn't click.

36:28

And you can get a response from one of

36:29

us or from both of us and we'll each

36:32

share our perspective. We also run live

36:34

coaching events periodically where you

36:36

can ask questions face-to-face and

36:38

there's also a mix review feature where

36:41

you can submit a mix and get expert

36:43

feedback from Gabe himself. A lot of

36:45

people in the membership are working

36:47

through the same problems and hearing

36:49

responses to other people's questions

36:52

tends to move you forward in ways that

36:54

watching videos won't do on its own. You

36:57

still have to put the practice in

36:58

yourself though to actually hear

37:00

results. But having that support
