Pitch (key) : Changes the sound pitch or key, without affecting the sound tempo or speed. Playback Rate : Changes both the sound tempo and pitch, as if an LP disc was played at wrong RPM rate. See here for example sound clips of each control mode: http://www.surina.net/soundtouch/soundstretch.html#examples The SoundTouch library is suited for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects - See here for a list of applications that use SoundTouch library: http://www.surina.net/soundtouch/applications.html
