Video duration: 0s 3h 5m Appropriate for all Updated Jan 24, 2014


This installment of Foundations of Audio explains one of the most essential ingredients in audio mixing, reverb—the time it takes for sound to bounce, echo, and decay during a live performance or recording. Reverb gives a natural richness to your recordings, which is possible to reproduce. Producer and audio engineer Alex U. Case covers the acoustic, mechanical, and digital means for creating reverb, and charts the parameters (room size, density, etc.) you'll need to know to take advantage of the original recording space and enhance it in post. He then shows how to simulate reverb digitally with effects, adding timbre, texture, and contrast, and improve the sound of your mixes with a sense of space and depth.

These techniques can be practiced with the free Get in the Mix sessions, currently available for Pro Tools and Logic Pro.

Topics include:
  • What is reverb?
  • Understanding how acoustic reverb works in rooms
  • Working with the signal flow, effects loops, and available CPU resources
  • Understanding core parameters, like reverb time and pre-delay
  • Simulating space
  • Creating nonlinear reverb
  • Building pre-delay effects
  • Using reverse reverb
  • Using convolution correctly
Audio + Music


I'm Alex Case. Welcome to Foundations of Audio: Reverb. From caves to cathedrals, amphitheatres to amplifiers, humans have used reverberation or reverb to augment sound and music for millennia. Whether it occurs naturally, designed into the architecture of a space, or is artificially manufactured in the studio, reverb is a special effect we find very appealing sonically. There are many types of reverb that produce a wide variety of sounds and in this course we'll look at the most common ones, as well as some of the more advanced reverb effects.

I'll start by covering the fundamentals of reverb, including the devices that make it and how they work. (music playing) Then I'll break down the common controls of a reverb effect, showing you how to set the Reverb Time, pre-delay, wet dry mix, diffusion, density, and other parameters. I'll demonstrate how to use digital Reverbs to simulate realistic space on your studio tracks. (music playing) I'll then explain how to use springs, plates, and chambers to modify the timbre of your tracks.

We'll take a look at how convolution Reverbs work so that there's no mystery even with the newest reverb technology to hit our studio. (music playing) I'll show you how to use gates on your reverb returns and your room tracks for that obvious '80s flair or for more subtle track enhancement. Throughout this course I'll also provide you with guided exercise content in the form of Get in the Mix demonstration sessions that you can open up in your own digital audio workstation. Watch the video about Getting the Mix content to learn more about this unique learning experience.

Now, join me in this high-end professional recording studio as we continue the Foundations of Audio Series with Foundations of Audio: Reverb.
