Hello everyone,
I am working on MacOSX, and on the android emulator.
I am trying to use AudioRecord, which put the recorded audio data into
a ByteBuffer. However this buffer is filled with 0 at the end of
recording.
Here is the code:
public class AudioAcquisition {
private AudioRecord ar;
private ByteBuffer bb;
private int bufferSize = 200000;
public AudioAcquisition() {
bb = ByteBuffer.allocateDirect(bufferSize);
ar = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);
ar.read(bb, bufferSize);
}
public void start() {
bb.clear();
ar.startRecording();
}
public void stop() {
ar.stop();
ar.release();
}
}
Since I want to work on the audio data for signal processing, this
class seems promising. Could anyone help with it?
Thanks a lot!
