Speex dev - Aug 2005 - comfort noise generation

hi,

when VAD is enabled, can i make the decoder simply produce comfort noise in the
event that no voice was detected?

i'm working on a p2p voice app. when no voice is detected, i'm thinking
that i can make the transmiting endpoint send a signal to notify the remote
endpoint that VAD is in effect, instead of having to send the whole packet that
doesn't have voice anyway. on the receiving endpoint i would like to play
comfort noise.

how can i do this with speex?

thanks,
ronald

I think (haven't played with that in a while) all you have to do is
enable VAD and DTX.
