Additive Synthesis

slide-33
SLIDE 33

Additive Synthesis is the process of creating new sound waves by combining one or more Sine waves together

Beats

slide-38
SLIDE 38

When two waves are very close to the same frequency, they will shift in and out of phase giving the sensation of beats The Beats Per Second can be found by the difference between the 2 frequencies

222Hz - 220Hz = 2 Beats Per Second

Project: Sound Exercise 1: Analog Synthesis

Create a synthesized sound using BEAP . Save the Max patch so that you may present your sound in class.
