The problem with agc is thatit changed levels a lot within the same speaker and thus lessened the sound quality when I was using it. William King <william.king@quentustech.com> wrote:

I think the best way to solve this is by doing AGC first. This should make sure audio level is similar for all participants.

There is also the preprocess app which uses a media bug in the core for a variety of things but is incomplete it's using a bit of code from speex so we can certainly improve that as well.

If you wanted to implement something like this you could do so as a media bug, it does not need to touch mod_conference in any way. Take a look at mod_ladspa for an example of a similar module that modifies audio using a media bug. Give it a try and see if you can get something working.

While I don't have a problem with the concept of noise filtering I have to point out that each member of the conference can have his or her own noise level setting. From fs_cli:
conference <conf name> energy <member_id|all|last|non_moderator> [<newval>]
You only need to apply it to the person who is in the noisy location. In fact, in the example configuration the user can dial 9 to increase the energy threshold (for when he's in a noisy environment) or press 7 to decrease the threshold. Pressing 8 will reset the energy to normal, which I believe is 200.

Hi,
I talked about this a while back on the channel, the way how energy-level is implemented in mod_conference isn't the right way to handle noise in my opinion because the participants that get bridged would have a different noise floor depending on where they are located, so if I set the value of energy-level too high to accommodate one participant, any other participant in a quite sitting would never get bridged, I proposed we should tackle this the way Asterisk does using a denoise dialplan function (https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Function_DENOISE), we can use libav for noise filtering on the muxed audio. I'm willing to contribute if one of the devs would help me out regarding implementation. Any comments?
