Hi,
I have a rather old pair of Sennheiser e500 wireless systems (ENG type,
portable on both ends). On the transmitter, there is an option for line
level. I guess the newer versions keep that option. At least this does
work for balanced line levels with the appropriate cable and the
gain/sensitivity set to its lowest setting.
It's rather common to use wireless between an ENG mixer and a camera.
Hope this helps
Cheers

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.

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
