Thank you Mark for the reply.
I am here uptil now.
int bufferSize =
AudioRecord.getMinBufferSize(8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
AudioRecord recorder = new
AudioRecord(MediaRecorder.AudioSource.MIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,bufferSize*4);
recorder.startRecording();
al.length(4000);
byte[] tempBuffer = new byte[bufferSize];
bufferRead = recorder.read(tempBuffer, 0, bufferSize);
for (int idxBuffer = 0; idxBuffer < bufferRead;
++idxBuffer) {
Log.i(""+idxBuffer, ""+tempBuffer[idxBuffer]);
}
recorder.stop();
return tempBuffer;
which is uptil step 7 in my above post. I dont know how to proceed
from here. I tried to pass this byte array on to the server (which
accepts above format), and the server responded me with incorrect
format error.
Do you have any idea how to proceed from here?
