Four years

Four years and what seems like a lifetime ago, I jumped aboard the ship Collabora Multimedia, and set sail for adventure and lands unknown. We sailed through strange new seas, to exotic lands, defeated many monsters, and, I feel, had some positive impact on the world around us. Last Friday, on my request, I got […]

Androidifying your autotools build the easy way

Derek Foreman has finally written up a nice blog post about his Androgenizer tool, which we’ve used for porting PulseAudio, GStreamer, Wayland, Telepathy and most of their dependencies to Android.

i’m in yur analog gain, controlling it

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 […]
