Longish day, but I did want to post something fun before going to sleep – I just pushed out patches to hook up the WebRTC folks’ analog gain control to PulseAudio. So your mic will automatically adjust the input level based on how loud you’re speaking. It’s quite quick to adapt if you’re too loud, but a bit slow when the input signal is too soft. This isn’t bad, since the former is a much bigger problem than the latter.

Also, we’ve switched to the WebRTC canceller as the default canceller (you can still choose the Speex canceller manually, though). Overall, the quality is pretty good. I’d do a demo, but it’s effectively had zero learning time in my tests, so we’re not too far from a stage where this is a feature that, if we’re doing it right you won’t notice it exists.

There lot’s of things, big and small that need to be added and tweaked, but this does go some way towards bringing a hassle-free VoIP experience on Linux closer to reality. Once again, kudos to the folks at Google for the great work and for opening up this code. Also a shout-out to fellow Collaboran Sjoerd Simons for bouncing ideas and giving me those much-needed respites from talking to myself. :)
