No problem at all, and thank you. Keep in mind that the retail price
I'm going after for these audio cards is in the thousands, even for
the economy model. I want a design that's equivalent to tens of
thousands of dollars in pro equipment that we sell for only a few
thousand due to the economy of the open source model.
From the feedback I got on the Linux Audio Developers list I don't
think thats going to happen.
In summary:
High end pro audio stuff costs thousands. Not 10's of thousands. And
most of that is not in the sound card. A pro setup can be produced
with currently available sound cards that range in $600 - $1300.
That said there _was_ interest in a fully open sound card but only in
the same feature/dollar range as whats available.
I think that the best target would be the home audio market -- a card
with the sound quality needed to drive a good audio system or home
theater sound system.
People said they would help but I got very little back in the way of
proposed specs. Low latency seemed important.
That depends on the CPU that you are using for the mixer, you need a
multiply and an add for each input channel X 2 for stereo.
There was specific interest in firewire and some interest in USB2 audio cards.
Perhaps a fire wire box would be better than a card. This does
eliminate part of the EMI pickup problem.
Audio accelerated or "DSP" cards have fallen out of favor in all the
but most specific of apps. A dual Athlon64 or Opteron seup can do
native signal processing fast enough to handle most everything.
The only thing that you really need a DSP for is the 5.1 surround sound
and the output filters.
