Hello,
every cheap systems I've tested to send data (video or sound) wireless don't work when the emitter moves to have a robust connection with a professional sound quality, you should use a professional emitter like Shure UR1 with appropriate receiver. Those can be found in any good audio hire.

For a wearable live performance computer, I am looking into the options of sending wireless audio from Pd to a PA sound system and other listeners.
In a first experiment I've tried a Linex FM transmitter. Audio quality is good enough, and FM transmitters do not introduce latency. This option is cheap and flexible, as the signal can be received by simple radio's, which are even built into cell phones and media players. I would need to boost the transmission a bit to make it more reliable. This will of course make the equipment illegal. Even then, the risk that someone else is transmitting a stronger signal on the channel can not be excluded.
Another option could be to send audio over Wifi. This would require WLAN to be available, and one extra computer (with audio interface) as a receiver. To avoid extra latency the audio should be sent uncompressed, like [udpsend~] / [udpreceive~] can do it. This has the risk of packet loss and serious dropouts.
I've been searching for 2.4 GHz wireless music receivers and found things like this: http://www.sitecom.com/en/wireless-music-streamer/wl-061/p/203. They seem to act like external soundcards for your computer. In Linux though I've never managed to properly connect multiple soundcards with Pd (in OSX it's easy using the Aggregate Device Editor from Audio MIDI Setup). Also I guess these devices introduce huge latency. With audio over bluetooth headsets I've experienced latencies up to a second.
Does anyone use a satisfactory method in practice, to send audio from Pd without wires?
Thanks, Katja
