Nowadays, of course, they can be independent (but don’t have to be). You can adjust pitch while maintaining speed, and adjust speed while maintaining pitch.

Here are some quick notes to myself on pitch and time shifting in Ardour, based on experiments I did yesterday. Read the rest of this entry »
