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: http://cnmat.berkeley.edu/publication/compact_120_independent_element_spherical_loudspeaker_array_progr regards, Peter Folderol wrote: > 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: > > On Mon, 23 Nov 2009 14:39:48 +0100 (CET) > karl@xxxxxxxxxxx (Karl Hammar) wrote: > >> Folderol: >>> On Sat, 21 Nov 2009 12:25:36 +0100 (CET) >>> karl@xxxxxxxxxxx (Karl Hammar) wrote: >>> >>> <snip> >>> >>>> 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): >>>> .
