Foundations of Audio: Delay and Modulation
In this installment of Foundations of Audio, author Alex U. Case explains the fundamentals of delay and modulation effects and how to apply these effects, technically and creatively, to improve the sound of a mix. The course covers adjusting individual parameters such as delay time, level, and feedback; working with long delays to create echoes, enhance groove, and add support; using delay modulation for chorus and doubling effects; and dialing-in spectral effects from delay, such as flanging. This course also includes Get in the Mix (GITM) sessions for both Avid Pro Tools and Apple Logic Pro. Exercise files are also included with the course.
- Adjusting the delay time, level, and feedback parameters
- Utilizing a low-pass filter and polarity reverse
- Setting up an effects loop
- Setting the delay time by tempo or by ear
- Understanding the distinct uses of short, medium, and long delays
- Adjusting modulation rate, depth, and shape
- Adding double tracking and spreader effects
- Manipulating tone with constructive or destructive interference
- Creating a comb filter and flange effect
- Hey, I'm Alex Case, and welcome to Foundations of Audio: Delay and Modulation. In this course, we'll look at the most common delay and modulation effects, including echo, slapback echo, double tracking, chorus, flanger and comb filter effects. You may not have heard of all of these effects by name, but I'm certain you've heard all these effects in the music you listen to. I'll start by covering the fundamentals of delay, including the devices that make it and how they make it. Then, I'll break down the common controls of a delay effect, showing you how to set the delay time, level and feedback parameters.
I'll demonstrate how to utilize long delay times for specific effects, such as delaying single words, creating groove delays on guitar tracks, and making use of slapback echo. I'll then explain how to utilize modulation rate, depth, and shape to create chorus, double tracking, and spreader effects. I'll then cover techniques for making use of constructive and destructive interference to create effects that manipulate tone, such as flanger and comb filter effects.
Lastly, I'll integrate all of this and discuss how to use several types of delay in one full mix. (pop music with several instruments overlayed) Throughout the 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 work station. Now, let's get started with Foundations of Audio: Delay and Modulation.
