[Speex-dev] Proposed AGC additions
Fri Jul 2 20:11:34 PDT 2004
You're right. The AGC gain does not max out when using VAD
(via the preprocessor). So instead of not transmitting when
the AGC max gain is reached, I now do this instead:
Start the call with VAD enabled and AGC disabled. When speech
is detected, disable VAD (if 100% continuous transmission is
desired for the call) and enable AGC. This seems to be working
reliably so far.
However, I forgot to mention before another reason why it's
good to be able to set the max AGC gain. One of my users
reminded me of it tonight: he wanted to be able to limit the
max AGC gain so that when he's not speaking, the AGC doesn't
pick up on other sounds from the room.
