A time domain granular pitch shifter. Grains have a triangular amplitude envelope and an overlap of 4:1, and use linear interpolation of the buffer.
The input signal.
The size of the grain window in seconds. This value cannot be modulated. The minimum value is 3 sample periods. If you supply a smaller value, it will be rounded up to the minimum.
The ratio of the pitch shift. Must be from 0 to 4.
The maximum random deviation of the pitch from the
A random offset of from zero to
Output will be multiplied by this value.
This value will be added to the output.
