The last attachment is not ok.
I will check the device.

Please check this one. It should be 10s audio, But I use vlc play it.
It only 2s noise.

>10 seconds of G722 have to be 4-5 times larger (because of the

>How did you create the sample?
I create the sample by record the stream uploaded by the device through the tcp socket.I make a software listen a port then the device establish a tcp socket to the server and report the stream.I put the second right one in attachment.
