  • DJ usage where it is very useful to be able to control playback speed and pitch independently.
  • Language learning where adjusting speed without affecting pitch is very useful.
  • Audio book devices where speed control without affecting pitch is convenient.
  • Karaoke devices where pitch control can be used to match the range of the karaoke singer.

The Pitch / Speed Shifter can be downloaded from the VSDSP Forum.
