Sandeep,
SoundPool leverages MediaPlayer service to decode the compressed audio into
a raw 16-bit PCM stream, which I thought you could refer to its
implementation.

Freepine,
I have looked at Soundpool, it does not solve my problem. To further
clarify, I need to implement the following (pseudo code) api for my
application. I do not need to play the sound.
public short[] getPcmData(String audioFilename, int
seekPositionInSeconds, int durationInSeconds);
Whe
You might want to take a look at SoundPool class and its corresponding
implementation in native layer, which could be a good reference if the class
itself doesn't satisfy your needs:)

Can you be more precise about what your application does? On quite a
few devices (and especially on the Dream/G1) Android fits tightly with
little room to spare, so it's unclear that we'd be accepting
contributions for entirely new applications.

Hi Sandeep,
You can put the if condition in the parser to read only till 10 sec
and take the PCM samples from decoder output to a file

My application needs to extract a 10 second portion of a audio file in
PCM format and store it.
On other platforms I have been doing this in Java using Jlayer
decoder, but once I ported that to Android, it ran extremely slowly.
It takes almost 50 seconds to decode a 10 second sample !
