Anyone can help me by giving advice for full duplex auido recording and playback.There exist two approach for audio playback.One using datasource+sourcestream and another one using inputstream.Using which approach i can get the full duplex audio.  Again,which handset exactly support full duplex audio.I am using blackberry bold 9000.

Both will work. I am using a circularbytebuffer.

Just remember to modify the read to feed the player the correct header.

The 9000, 8900 and 9700 are the devices I've tried it on.

The biggest problem is the buffering delay on the incoming audio when using OS 5.0....

have you used two application one in background and another in foreground??

at last solved::

Not sure if background or foreground matters and not sure if 2 processes or 2 threads matter.

CMDA or GSM may show differences. I am curious how come the phone application itself can fulfill full duplex. Maybe it's a little on the J2ME audio manager for CMDA devices. It seems ok on GSM devices.

The phone application is a native app, not a java app.

@ava: Have you tried full duplex in storm2 9520 or in strom series phone?.

yes there is a buffering delay on the incoming audio when using os 5.0, have to give a try on os 6.0 and above.
