Pitch Shifter

A pitch shifter is a type of effects pedal  that changes the pitch of an audio signal. Pitch shifting is the process of raising or lowering the pitch of a sound by a certain number of musical intervals. This can be used to create a variety of effects, such as harmonies, octave shifts, and more.

There are several types of pitch shifters available. Some allow you to set the amount of pitch shift and the interval of the shift, while others offer more advanced controls, such as the ability to create harmonies or shift the pitch of individual notes within a chord.
