This may be impossible but is there any way that I can get a smaller
buffer size
for AudioTrack than what is provided by getMinBufferSize method?
This is how I am instantiating AudioTrack right now:
SR = 44100;
bufSize = AudioTrack.getMinBufferSize(SR,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SR,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufSize,
AudioTrack.MODE_STREAM);
With sample rate of 44100, getMinBufferSize always returns 4800.
If I try to make the buffer size smaller than 4800 then I get the
following error message:
E/AudioTrack( 318): Invalid buffer size: minFrameCount 1200,
frameCount 600
E/AudioTrack-JNI( 318): Error initializing AudioTrack
E/AudioTrack-Java( 318): [ android.media.AudioTrack ] Error code -20
when initializing AudioTrack.
D/AndroidRuntime( 318): Shutting down VM

I/CheckinService( 59): From server: Intent
{ action=android.server.checkin.FOTA_CANCEL }
E/AndroidRuntime( 318): java.lang.RuntimeException: Unable to start
activity
Does anyone has any ideas how to over come this problem?
