Question 4

Sound characteristics of a flanger

Answer 4

Comb filtering-Sounds combined with a very short delay of itself, causing some frequencies to get louder (Because they line up), and some frequencies get quieter (Because they cancel out)

Question 7

How does digital reverb work?

Answer 7

As a signal reaches a reflective surface, it bounces back
This happens on every surface
The reflection then bounce back themselves
Every time the signal is degraded

Question 8
