Hi, I have capture a pcap through wire-shark , which contain data of G729 payload type . Now I saved it in .raw file and decode it in .pcm using the decoder and finally got the .au file . But when I am playing that file it is generating noise. Plz tell me why it is generating noise. asked 27 May '11, 00:32  rahulgupta |
One Answer:
Probably it depends on the G.729 converter you are using. I have a lot of problems with Asterisk file convert function and free Intel g729 lib. If the noise is small then it could be the comfort noise. Have you compered the end-to-end quality and captured quality? answered 27 May '11, 02:45  jakan |
