This command adds phase-shifted high-frequency distortion to each selected Sound to create new upper harmonics, and can be used to enhance dull recordings and to improve speech clarity and intelligibility.
Soft clipping distortion generates only low-order harmonics, and asymmetric clipping generates both odd and even harmonics.
The resulting new Sound(s) will appear selected in the list of objects.
