[IDEA] Multiroom Audio

[maartin]

Just found this, not exactly an request:

Bark!

Quote "Low latency multi-receiver synchronised audio streaming for local networks."

Sounds interesting to me, but i am not a software dev. Maybe somebody will check if this is of interest for moode.

A quick glance at the specs suggests this isn't much different to the multiroom already in moOde, unless I've missed something?

On the surface it's similar to what is used currently in moOde which is the TRX Realtime audio over IP toolset written by Mark Hills plus some enhancements I added to support integration into moOde. The repo is maintained by @bitlab https://github.com/bitkeeper/trx and the enhancements are in release 0.6.

The main differences between TRX and Bark are below:

Code:

--------------------TRX------------------------------Bark-----------------------------
Audio format        Compressed (Opus) 16/48K PCM     Uncompressed 16/48K PCM
Clock sync          No                               Yes
ALSA output         Yes                              No (only Pipewire and Pulseaudio)

TRX does not use clock sync to maintain to-the-ear sound synchronization but rather relies on low network latency (few milliseconds) and packet drop recovery in the Opus CODEC.

Bark includes clock synchronization which is needed to maintain to-the-ear sound synchronization on higher latency (> few milliseconds), inconsistent latency networks or when sender/receiver throughput is inconsistent.

I might ping the dev to see about ALSA support and whether native sample rates can be supported.
