sound playback rate?

is it possible to change the playback rate of a sound?

i know this is supported on iPhone at least due to apps such as Chippy and Talking Perry, where it just plays it back pitched up (higher=faster, lower=slower)

(i think Talking Carl is a bit different, in that i think it actually pitches the audio up without altering the speed)

thanks
