Internal Name:

pitch_shift

Plugin Type:

effect

Description:

The pitch shift effect modifies the signal by changing the speed of the content, but with keeping the original length. You can select the relative speed either by factor from 1/10 to x5, or as a percentage from 1% to 400% of the original speed.

A speed factor below 1.0 pitches the signal down (lower voice, makes voices sound older), factor 1.0 does no change and a factor above 1.0 pitches the signal up (higher voice, mickey mouse effect).

The implementation is based on the work of Jeff Tranter and Stefan Westerfeld

Parameters:
speed

Factor for changing the speed, has to be a floating point number between 0.001 and 4.0.

frequency

Frequency internally used by the filter in Hz, has to be between 2.0 and 10.0.
