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.
| in |
The input signal. |
| windowSize |
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. |
| pitchRatio |
The ratio of the pitch shift. Must be from 0 to 4. |
| pitchDispersion |
The maximum random deviation of the pitch from the
|
| timeDispersion |
A random offset of from zero to
|
| mul |
Output will be multiplied by this value. |
| add |
This value will be added to the output. |
