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.<div>

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:<br><br><span style="font-family:courier new,monospace">conference <conf name> energy <member_id|all|last|non_moderator> [<newval>]<br>
</span><br>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.<br>

Hi,<br><br>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 (<a href="https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Function_DENOISE" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Function_DENOISE</a>), 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?<br>
