Tangentially related, I recently had some hand-me-down high-end full tower speakers lose their integrated subwoofer amps. I bypassed them and wired in an external amp but people said the integrated DSP would be missing. That's when I learned about CamillaDSP [1] and CamillaFIR [2]. I got a calibrated UMIK-1 microphone and did a frequency sweep in the room. Then I applied the Camilla-computed FIR filter to my snapcast-sourced music stream on the Raspberry Pi 3 B I have networked into the living room. Now I have room-corrected and loudspeaker corrected fancy DSP and the speakers sound better than ever. Pretty fun, and very cheap. The Pi3 runs it using about 20% of its CPU. Not bad! I did the same process up in my office with some desk speakers and they sound great too (that time using EasyEffects to apply the filter in real-time rather than

Yeah, Sonos is very much the Apple of this space. A solid, user-friendly implementation of several pre-existing concepts into a cohesive product - no small task. I don't think the technologically important parts of this are patentable though, there's both prior art and the obviousness standard to worry about. But very much like Apple's 'rounded corners' case, they've gone after (IMO) obvious UI functionality for such a system to extract money from their competitors. If you are just interested in the synchronized Audio-over-Ethernet part, AES67 is the industry standard, and a pretty complete open-source implementation can be found at https://github.com/bondagit/aes67-linux-daemon , though AES67 is itself a composition of existing standards, fundamentally it is mostly composed of SDP for sessions description, RTP for media, and PTP for cloc
