Well, I'm trying to work with it. I think I have understood how to use
it (there's some sound going out), but that's not perfectly.
Here's my testing code:
(There's some strange things in it because now I'm trying to use
Producer/Consumer Threads whit it)
private void makeAll(double frequencyLeft, double frequencyRight) {
final double RAD = 6.283185307179586476925286766559;// 2.0 *
Math.PI
int size = android.media.AudioTrack.getMinBufferSize(44100,
AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT) * 2;
AudioTrack oTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
44100,
AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT, size,
AudioTrack.MODE_STREAM);
oTrack.play();
int i = 0;
short[] vai = new short[size * 2];
int j = 0;
for (j = 0; j < vai.length; j++) {
vai[j] = (short) (Math.sin(RAD * frequencyLeft /
44100.0 * i) *
32767.0);
i++;
j++;
vai[j] = (short) (Math.sin(RAD * frequencyRight /
44100.0 * i) *
32767.0);
i++;
}
while (true) {
oTrack.write(vai, 0, vai.length);
i = i * 2;
if (i >= 44100 * 2) {
return;
}
}
}
Maybe this will help you.
