Thinking a bit more about this, there is another challenge closely related to the delay issue. If the speaker input is analog, you'll have a DA converter in each receiver. This needs to get its sample clock *from the received data* unless you're prepared to resample the signal after decoding. Since there can and will be significant jitter on the wireless data timing, reconstructing a stable clock from this won't be easy. If the speaker input is digital that same problem is shifted into the speaker - the question is then how much clock jitter it is prepared to accept. One solution is to distribute the word clock by cable, but this again puts the wireless interface into question - the same cable could as well carry the audio data. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
