PulseAudio & Compress Offload: A Linux Audio Journey 🎧

While PulseAudio has been a standard component in desktop and embedded Linux for a decade now, it was always written with uncompressed audio data in mind.

To save power. modern SoCs often support "compress offload", where an efficient DSP can receive compressed MP3/AAC/... data, decode and render it to be played out.

In this talk, I'll describe how this was implemented in PulseAudio, what challenges and tradeoffs were involved, and what the future might hold for this work.

linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
