    Hi,<br>
    <br>
    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.<br>
    It&#39;s rather common to use wireless between an ENG mixer and a
    camera.<br>
    <br>
    Hope this helps<br>
    Cheers<br>

      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.<br>
      <br>
      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&#39;s filming. For this purpose it is ideal. Then I thought
      it would be good to use the computer in it&#39;s wearable mode for
      public performance. I figured that one of the many wireless
      solutions would suit the purpose, but didn&#39;t reckon with the
      unusual requirements.<br>
      <br>
      Further searching brought me to a new technology &#39;PurePath&#39; from
      Texas Instruments. It has a range comparable with WiFi (30m),
      while it seems to work with paired devices as in Bluetooth. I
      haven&#39;t seen consumer products with this technology, but
      development kits are available. A rather convincing demo is here:<br>

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

                          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&#39;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&#39;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&#39;ve been searching for 2.4 GHz wireless music
                          receivers and found<br>
                          things like this:<br>
                          <a href="http://www.sitecom.com/en/wireless-music-streamer/wl-061/p/203" target="_blank">http://www.sitecom.com/en/wireless-music-streamer/wl-061/p/203</a>.
                          They<br>
                          seem to act like external soundcards for your
                          computer. In Linux<br>
                          though I&#39;ve never managed to properly connect
                          multiple soundcards with<br>
                          Pd (in OSX it&#39;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&#39;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>
