What the Top 1% of Engineers Know About
Mixing with Delay That You Don't
Discover how the best engineers in the game craft truly remarkable mixes by using "micro" and "macro" delays—and how you can too!
Want to keep learning and growing as an engineer? Read to the end...
Great mixers do TWO things:

One's easy to hear.

The other is barely audible… but you’ll know when it’s NOT there.

For a remarkable mix, you need both.

I'll prove it…

You see, if you're like most engineers and producers, you got into mixing because you want to release music that you're proud of.

You don't want your mix to just sound OK... you want a mix that leaves your clients and colleagues speechless.

But you probably didn’t expect that mixing would be THAT hard, right?

I’m not surprised. Because that’s exactly how I felt…
I Didn’t Figure This Mixing Thing Out Myself
Dan here, founder of the Pro Audio Files.

Flashback to 10 years ago… I probably felt how you feel now.

I wanted nothing more than to produce professional sounding tracks.

And you know what?

I was getting pretty close!

As a musician, I had a good ear for the overall levels of a mix.

And I could hear all the obvious things… Like a deep reverb, or a clearly noticeable delay.

I’d say my mixes were about 80% to the point where I could say, "THIS is what I want it to sound like.”


There were lots of things I had no clue about.

Like the fact that top engineers often use 2, 3, and even up to 5 delays in ONE session!

Some pros don’t even like to use reverb—they prefer to rely on delay entirely.

Now, I didn’t figure this out myself. But more on that in a sec…

Because today I’m going to share this simple approach for mixing with DELAY that a handful of top mixers have been using for years… and how YOU can use it too.

In fact, anyone (...with two ears) can use it to transform their mixes.

And, to my knowledge, no one has shared it before.

But first…
Why a BORING Mix Won’t Cut It in 2020
Listen to your favorite record that’s out right now...

It could be a hip hop track.

It could be a country song.

It could be a pop ballad.

You’ll notice they all have ONE thing in common.

These mixes that reach millions are… exciting!

There’s DEPTH.

There’s DRAMA.

There’s EMOTION.

And there’s always something happening...

A delay throw here.

A crazy distorted vocal repeat there.

A subtle flange or chorus to change the sonic texture.

The average listener may not be aware of what’s going on like you… but they’ll know when it’s missing.

The truth is, interesting sounding mixes have always captured audiences.

But it’s more true now than ever.

(And, frankly, clients and artists expect it.)

Unfortunately, this is also why my mixes never got the reaction I was hoping for… because they just sounded BORING.

The worst part?

No one I knew could tell me how to get it right.

Either they didn’t know… or they didn’t want to tell me!

The GOOD NEWS for you is that the times have changed!

I’ll explain.
Coming Up as a Mixer USED to Take Years
While I started building this site over a decade ago…

…Matthew Weiss was rising through the ranks as a mixer:

Matthew Weiss with Akon

"Ever since I got electrocuted running sound in high-school I knew... I want to do this for the rest of my life!" — Matthew Weiss (Grammy-nominated mixer; Akon, Ozuna, Becky G, Anitta, Chris Brown, Rick Ross, Swae Lee, Nico & Vinz, CADE, Damian Marley, SisQo' and many more)
Continually getting more clients… raising his rates… getting more clients… raising his rates again...

From an unpaid intern, still working his day job at a pizza shop...

…to becoming the head engineer at Akon’s KONVICT studios in Los Angeles.

Today, Matt is an in-demand engineer with the luxury to TURN DOWN clients.

It took almost 10 years... but here’s what’s important:

At each stage of his career, Matt had experienced mentors who were willing to share their secrets.

In his interview on Pensado’s Place he jokes, “I’m the last living intern."

So, trusted mentors are even harder to come by now than a few years ago.


Now there’s a way to soak up all those years of experience... in a matter of days!

And you don’t have to wash dishes or get coffee once!

You see, when Matt and I linked up, we decided to create mix tutorials for people who can’t afford a really good engineer, but have talent and drive and want their music to be heard in the right way. As well as for engineers who want to continually learn and get better.

In other words… for people like me and you.

And things took off...

Over 9,462 engineers, producers, and songwriters have joined Matt's training courses.

Today I’m PUMPED to announce a brand NEW course.

A course I wish I had ten years ago!
How Top Engineers Mix With Delay Today
So how do you give YOUR mixes that professional sound?

The truth is:

Great engineers do things you FEEL more than hear.

That’s why it’s so hard to pin-point just by listening. You’ll just know “something” is missing in your mix if it’s not there.

Now, Matt’s secret method…. is actually not revolutionary at all. Legendary mixers have used it for years.

It doesn’t require any special talent.

Or special gear.

It has just never been shared and explained before.

You see, when you hear delay you’re probably thinking rhythmic echoes, slap backs, delay throws...

…and that’s part of it. Matt calls this MACRO delay.

But then there’s also MICRO delay...

This is when a delay happens within an extremely short time… and it completely changes the game:

Micro delay almost functions like a different tool… and puts a whole new world of effects at your fingertips: Chorusing, "stereo-izing", changing the tone and texture of instruments…

Matt even has a micro delay he uses on his mix bus!

Sounds crazy but... there's actually a scientific reason it works.
How to Take Advantage the Psychoacoustic Phenomenon Known as the "Haas Effect"
I won’t get too technical, and Matt explains it better than I can.

In short...

These short delays are too quick for our brain to register as distinct repeats.

But a psychoacoustic phenomenon known as the Haas Effect changes our perception of sounds that are even slightly delayed. 

When Matt breaks it down in simple terms (for drummers, like me)... end up with a powerful way to use MICRO and MACRO delays in your mixes.

Because the real “magic” happens when you COMBINE micro and macro delays, and add in distortion, EQ, compression, and automation…

And that’s exactly what Matt will show you inside his all-new course:

If You Think You Know Delay… Think Again!
Delay is an ESSENTIAL mixing tool, and this course will completely change the way you use it, so you can create remarkable mixes that leave your friends and clients speechless.

You get 3+ hours of in-studio video mix training with Matthew Weiss as your personal mixing mentor. You’ll see everything that’s covered below…

In short:

Matt walks you through his complete process and shows you step-by-step how to use the power of DELAY to transform your mixes… from boring to STUNNING.

Just Imagine…

Listening to your favorite tracks, comparing YOUR mixes, and thinking, “mine sound just as good!"
You’ll Be Crafting Remarkable Mixes—
With the Gear You Already Have!
In fact, all you need is a computer, your DAW stock plugins, and a pair of headphones.

It doesn’t matter which DAW you use, either.

Because everything Matt teaches applies to any mixing software. You could use Pro Tools, Logic, Reason, Ableton, Fruity Loops, you name it…
Testimonial 1
This is a big reason people love Matt as their mixing mentor.
Do you need special Delay plugins to get results?


Look… If your mixes are “stuck” at a certain level, and it feels like you’ve tried everything to get better... It’s NOT your fault.

The plugin industry makes BILLIONS by making you believe that you need the latest and greatest audio gear to create remarkable mixes. Nothing could be further from the truth…

More plugins will often just send you down another the rabbit hole…. instead of doing the one thing that’s proven to work: investing in your skills as an engineer.

Just like buying a nicer pen won’t make you a better writer, spending more on plugins won’t make you a better mixer.


These days every DAWs stock plugins are incredibly powerful. So you’ll be fine.
You Get Lifetime Access... So Watch the Videos Whenever It Fits Your Schedule
Maybe you’re wondering if you’ll have enough time to go through this training.

I get it. Life gets busy...

How Much Does It Cost To Get Access Today?

That’s why almost 10,000 engineers, producers, and musicians have joined Matt’s courses.

And it changes the way they approach their mixes forever!
Testimonial 2

Chances are, you’ve already spent between $500 to $5,000 or more for plugins, speakers, headphones, interfaces, mics etc.
