DIY Ethernet Audio Receiver

Posted by michael on from the fly-by-wire dept.

geo writes "I created this site to describe my latest toy: a digital audio multicast receiver. LANPipe receives 16-bit, 44.1 kHz audio multicast from a PC based server. The server uses a Winamp plug-in, so LANPipe can play almost any source format (mp3, ogg, uncompressed). It even has a digital audio output. The receiver uses a custom CPU written in VHDL and implemented on a Xilinx FPGA. This was a fun project that is best appreciated by fellow hardware geeks."

  1. Very slick.. by Garion911 · · Score: 5, Interesting

    I like this.. This would solve many of the problems I have with putting a computer near my stereo.. I don't have any space near it... SOmething small like this would be very very cool..

    One feature I would like to see is the possiblilty of "multiple channels", so that I could stream several channels at once.. So my GF, who likes country, can listen in the livingroom, and I can listen to my stuff in the basement, without having a computer at each location...

    Network Audio System has been around for as long as I remember.. Some pretty good pages here and here. In the case of NAS the hardware decoder is in the workstation.

    This is a pretty elegant solution for how to get your MP3 collection from your computer to your stereo(s). Think about it -- you can have your own radio station at your house. Add a wireless uplink, and you can carry it around with you. All for only $100! Made into a commercial product with an ASIC instead of an FPGA, you could probably put it on the commercial market for well under $200.


    Slashdotters, before you slam this thing, please consider the following facts:

    • not everyone has a spare PC or two lying around the house
    • some people DON'T have their PC sitting in the middle of their family room, right next to the stereo.
    • people value elegance

      If the geek value is not the main point, you can hook a small FM transmitter to your sound card and use standard FM receiver all around the house.
      I'm quite sure that with sufficiently low power, it can be used unlicenced all over the world(check your local legislation).

      It is not high-tech, but it could do the job for cheap, reusing existing infrastructure (the stereo). And if your Os can manage many souncards, you can transmit using different frequencies, for different music programs.
