android - Change speed of audio by transforming samples NOT the sound card speed (in Java) -

i have application "syncs" multiple devices playing same sound in java. in order need speed up/slow downwards sound playback.

i tried changing sound card's sample rate (via android's audiotrack api or java sound api desktop). unfortunately changing sample rate on sound cards introduces lag , "popping" noise.

so there way remove/add samples bytestream of sound info without making sound sound "weird"? perhaps library can this?
