We have at least two 'problem scenarios' here. One large outdoor in

_If_ the aim is multi-loudspeaker, wireless audio ... then one possibilty
is to physically distribute it.
This presumes one has the repetoire and are not using streaming from radio
or Internet (or 'live').

One can get a large repetoire (I won't say everything you have on your PC,
but it must be the case for some users) on an SD card.
So decode the piece(s) to speaker feeds ('D-format').
Put one channel (for each piece) on each SD card.
Distribute cards by hand ....

(SD cards must be comparable to XLR leads in price ... ? )

You just then need a master signal to:
-synchronise
-adjust volume
-select track
- ... ?

If you're outdoors then you can use GPS time for synchronization. In which case you can just program everything to start at a certain time and forget about communication.


and a large team of 'men in black' with hammers for disciplining wayward
loudspeakers.

Patentable?

Always.
