Some notes (this goes to LAU only please mirror to LAD if necessary):
Have a look into AVB it seems to become the de-facto standard if that is
possible (don't know about hardware/ethernet interface requirements)
Tim Blechmann has written an alsa driver for the digigram lx6464es card,
which is used in some ethersound products (Tim?)
http://en.wikipedia.org/wiki/EtherSound
Rimas Avizienis at CNMAT and Meyersound built hardware alongside a UDP
protocol to stream many channels of audio to custom built hardware, as
for example used in a 120 channel loudspeaker array:

Recent discussion on LAU morphed into an idea for an
Ethernet driven
sound card, and as this is now becoming a real development the
suggestion was made that it would be better to transfer the discussion
here.
The rationale in brief:
No proprietry hardware soundcard needed.
Almost all modern computers have reasonably fast Ethernet connections.
Potentially up to 20 channels per card - reality will probably be a lot
different!
FOSS drivers to connect Ethernet to whatever audio server is on the
computer - looking at jack right now.
FOSS within the soundcard module so that protocols/algorythings can be
tuned for best results.
FOSH design enabling hardware to be developed and inproved by anyone.
A number of people have shown interest in this, and we are at the stage
of starting to knock together some basic hardware for a feasibility
study.
State of play:

Ok, I should get
starting then.
Regards,
/Karl Would this project plan be ok:
software and hw: Karl
testing and spec's: Folderol
publication via web: anyone??
git repo: git://aspodata.se/openhw.git
mailing list: hopefully this list, else I put one up at my site
web site: ??
intial platforms (both by Atmel):
. ATNGW100 (cheap), and
. AT91SAM9260-EK (expensive)
Next step:
. set up development platform
. simple test with spi and shift registers
Regards,
/Karl
This is all fine by me, but I would make quite clear that if someone
comes along with access to a {loadsamoney} spectrum analyser I'd be
perfectly happy to step back and take a more supporting role.
