Hi Andy,

Pitch Shifting is the ability to change the key of a song after it's composed (eg. if a song key doesn't suit the vocalist you can change it to a more suitable key).

I use Tempo stretching mainly to speed up or slow down a song after it's composed eg. if the vocalist wants to sing it faster or slower. I've also used it to change tempo of songs to suit dancers where song needs to be to specific beats per minute tempo.

Vocal Pitch correction is a different ball game and would work on the vocal track after recording to correct any imperfections in the vocalist's pitching (eg corrections where he/she might go sharp or flat)

Hope this helps.

Kev.
