You should take into account the buffersize you passed along into the AudioTrack creation.

final int minBufSize = AudioTrack.getMinBufferSize(Application.PLAYRATE,
AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT);

out=new AudioTrack(AudioManager.STREAM_MUSIC, Application.PLAYRATE, 
AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT, minBufSize, 
AudioTrack.MODE_STREAM);

extraLatencyFrames = minBufSize/4;
