Subject: Re: [PD] wireless audio from Pd to PA system (katja)
Found more info about TI's PurePath wireless. Latency of wireless transmission is 768 samples minimum. Added to this must be the latencies of ad/da conversion.

Forget about it, this concept is only useful for home entertainment.

Thanks everyone for your answers.
The case is unconventional because a stereo line signal must be sent from the computer. Professional wireless systems assume mic or instrument. Consumer systems do transmit stereo signal, but without bothering too much about latency.
Frankly, I did not expect the difficulty to find a good solution. Initially I wanted the wearable computer for a music video which is to be recorded live with sounds from natural objects. I bought the FM transmitter so my cameraman will be able to hear the music while he's filming. For this purpose it is ideal. Then I thought it would be good to use the computer in it's wearable mode for public performance. I figured that one of the many wireless solutions would suit the purpose, but didn't reckon with the unusual requirements.
Further searching brought me to a new technology 'PurePath' from Texas Instruments. It has a range comparable with WiFi (30m), while it seems to work with paired devices as in Bluetooth. I haven't seen consumer products with this technology, but development kits are available. A rather convincing demo is here:

If this system can work with low latency it could be perfect for wireless Pd.

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
