For a wearable live performance computer, I am looking into the<br>
options of sending wireless audio from Pd to a PA sound system and<br>
other listeners.<br>
<br>
In a first experiment I've tried a Linex FM transmitter. Audio quality<br>
is good enough, and FM transmitters do not introduce latency. This<br>
option is cheap and flexible, as the signal can be received by simple<br>
radio's, which are even built into cell phones and media players. I<br>
would need to boost the transmission a bit to make it more reliable.<br>
This will of course make the equipment illegal. Even then, the risk<br>
that someone else is transmitting a stronger signal on the channel can<br>
not be excluded.<br>
<br>
Another option could be to send audio over Wifi. This would require<br>
WLAN to be available, and one extra computer (with audio interface) as<br>
a receiver. To avoid extra latency the audio should be sent<br>
uncompressed, like [udpsend~] / [udpreceive~] can do it. This has the<br>
risk of packet loss and serious dropouts.<br>
<br>
I've been searching for 2.4 GHz wireless music receivers and found<br>
things like this:<br>

seem to act like external soundcards for your computer. In Linux<br>
though I've never managed to properly connect multiple soundcards with<br>
Pd (in OSX it's easy using the Aggregate Device Editor from Audio MIDI<br>
Setup). Also I guess these devices introduce huge latency. With audio<br>
over bluetooth headsets I've experienced latencies up to a second.<br>
<br>
Does anyone use a satisfactory method in practice, to send audio from<br>
Pd without wires?<br>
<br>
Thanks,<br>
