Hello All
I'm accessing speex via jni, I have successfully
decoded and encoded data and capture and play it back in java. Now my
challenge is speex's echo canceller.
My capture and playback are not synchronized, so i got to use the method from
1.2beta2 right?
What's
the proper way to fit speex_echo_capture() and speex_echo_playback()
into the following procedures, assuming they were already wrapped by
jni properly?
speexInit();
final PcmRecorder r = new PcmRecorder();
final PcmPlayer p = new PcmPlayer();
r.setListener(new RecorderListener() {
public void recorded(Object source, byte[] bytes, int length) {
// WHEN A FRAME IS CAPTURED, THIS CALLBACK WILL BE TRIGGERED
int c = speexEncode(bytes);
// this is just for local playback, a demo only
speexDecode(bytes, c);
p.write(bytes, 0, length); // THIS IS WHERE A FRAME WAS
WRITTEN FOR PLAYBACK
}
});
p.start();
r.start();
Runtime.getRuntime().addShutdownHook(new Thread() {
public void run() {
speexDestroy();
}
});
