Where is the sound file that you have to access stored? – Jeff Gortmaker Aug 05 '12 at 19:15 — Jeff Gortmaker, Aug 05 '12 at 19:15

There's no built-in support in Android for directly retrieving the pcm data from an audio file. There's a nice open-source project, ringdroid, that would be a nice starting place for a roll-your-own code to read an mp3 or wav file. You can also look into including a third-party library into your code.
