How can I read and then write .pcm files using Java on Android, which I just recorded using the microphone at different frequencies?

// TODO Auto-generated method stub
File fileForSaving = new File(Environment.
                    getExternalStorageDirectory(),recordings/" + name + ".pcm"); 
File file = new  File(Environment.getExternalStorageDirectory(),"test.pcm");
int sampleFreq = (Integer)freqset[SELECTED_INDEX];

I want to save the file to fileForSaving with different frequency rates.

audioTrack = new AudioTrack( AudioManager.STREAM_MUSIC, sampleFreq, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufferSizeInBytes, AudioTrack.MODE_STREAM); – hanif s May 08 '13 at 04:59
here the sampleFreq is changing accordingly – hanif s May 08 '13 at 05:00
also i want to make changes to the track like entering the echo sound to this recorded track – hanif s May 16 '13 at 07:00
