Using the audio speed pitch changer

The output samples the original audio at a different speed using linear interpolation. A speed of 2 plays twice as fast and raises pitch by an octave; 0.5 plays half as fast and lowers it by an octave.

A worked example

The 0.1-second example becomes 0.05 seconds at speed 2. Speed and pitch move together.
