The Sony's 10 Hz to 22 kHz - looks like acceptable bandwidth for everyday live stage stuff. Unless you're expecting analogue pro-audio 40kHz & above (most pro-audio) or analogue 80kHz - 120 kHz (nice pro-audio Neve etc.)
There's SM Pro's 'TRANz' wireless DI box too - in living stereo no less:

I think contemporary wireless systems are expected to perform to more high-fidelity
specs than their bandwidth-challenged cousins of yore (Nady et al). The forums GearSlutz or TapeOp might turn up some answers too as the users are very knowledgable and come from many different pro audio backgrounds. My mate worked on The Wall and he showed me the wireless systems that they were using and introduced me to the 'wireless manager'. These systems were not 'reduced bandwith' - unless you're talking about transmitting HD about the place, and I've no idea how you would do that - i'm sure there's some gruesomely expensive system that would do it :) Rich

hello,
those are good for what they have been designed for and it depends on what you mean by "exellent sound quality"
I've made few tests on those few years ago and the bandwidth could be good enough to transmit guitar/bass signal but nothing else for me

Hi Katja one of these would do it - check with Thomann tech support for gain issues (these are Instrument Level input) They should be fine however as active guitar pickups (like heavy style EMG pickups) output quite high levels. These type of wireless systems tend to be very rugged, have excellent sound quality and long battery life - and you'll want these things.

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

Thanks for the links, Rich. The Tranz system comes close, with their stereo channels. It's a pity they don't have a body pack. Oddly, the manufacturer doesn't supply any technical specs for these devices.
