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.

Topics include:

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
