I’m looking for technical advice.
I’m working on a sound installation that involves broadcasting sounds in 12 Loudspeakers, dispatched in a room.
Each loudspeaker need to play an audio loop for a while, and then switch to another loop.
Just “playing” recorded material is not an option because after each loop it needs to pick up a random next loop, and all speakers need to change at the same time (after the current loop has reached its end).
The space of the room should be around 40 squared meters so the speakers don’t need to be super powerful.
I started with the idea of having one “big” computer with a 12 channel soundcard. But I realize that it makes a lot of wires from the sound card to the speakers.
Wireless audio seems to be complicated and very expensive.
So I’m exploring another route :
1 Raspberry Pi 3 running a Pure Data patch that tells (via WiFi) which file each of the receivers (Rasp Zero W) should play. Each “receiver” would run a PD patch with the file players.
Does it sound ok for you ?
Things that I might have overlooked :
- cheap wireless multichannel audio transmission
- ad hoc wifi on rasperries
- other platforms (bela ?)
- Any chance of making this battery powered ?
Thanks for your thoughts !
