i’m in yur analog gain, controlling it

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, […]

PulseAudio 1.1 (the echo release?)

Yep, if we keep this up, it could even become a habit! PulseAudio 1.1 is out. It’s mostly a bunch of bug fixes on top of 1.0. Most important of these are fixes for: a libpulse dependency on libsamplerate (if enabled) which would make our LGPL license invalid, broken Skype audio capture (because we changed […]

Alternate sample rates

I’ve just pushed a bunch of patches by Pierre-Louis Bossart that can have a pretty decent CPU/power impact. These introduce the concept of an “alternate sample rate”. Currently, PulseAudio runs all your devices at a default sample rate, which is set to 44.1 kHz on most systems (this can be configured). All streams running at […]

The week after that, we have the Kernel Summit, GStreamer Conference, Embedded Linux Conference Europe and LinuxCon Europe. I’m going to be at the last 3, and there’s some great […]

Well done, Adobe!

In an unsurprising turn of events, Adobe completely fails to play well with modern Linux systems. Well done, guys. Well done, indeed. p.s.: I was quite happy to see that the Google Talk plugin has proper PulseAudio support (thanks to the WebRTC née GIPS code, it looks like).

Hello … hello … hello!

I have a secret to confess. I’ve spent a great deal of time over the last few months talking to myself. I can’t say I haven’t enjoyed it — it turns out my capacity to entertain myself is far greater than initially suspected. But I hear you ask … why? Here at Collabora, I’ve been […]
