True, USB audio works wonderfully under windows and OS X. Sub 6ms
glitch free latency. But... Mark googling around I found discussions
you and I have had about USB/Firewire audio more than a year ago, then
resumed next year and now again for the third year:
Here's why I'm sadly of the opinion something like a custom 1394 card
More than two years pass and USB is still useless for low latency work
under linux. Anyone out there have a different experience?
USB audio is ubiquitous in the windows/mac world and is pretty damn
common umong linux users I'm guessing. (How many laptop users out
there?) USB audio is a perfectly reasonable technology despite whatever
predjudices people may have.
I'm left to believe that there is 1) not enough developer/user interest
to make USB audio work well or 2) linux is not up to the task of running
USB audio interfaces 3) (less likely) a strong bias against USB by
Now if 1 or 2 are true for USB, I'm guessing they'll be true for
FireWire, if 3 is the reason for USB audio err... "not working so good"
on linux well... there may be hope for FireWire.
Either way, I'm sorry but if we can't even have functional low-latency
USB audio, how could it possibly be that FireWire will be supported, now
add to it the task of developing the hardware?
Even were it to be supported, the USB user base must be absolutely HUGE
compared to any potential FireWire base.

I'm sure the generic 1394 drivers are approaching the performance of
windows now. But I'm operating under the assumption the audio end of
things are going to require a bit more coding.

Ah, Mark but we've tried for years haven't we ;-)

Mark it's a knoble cause and I support your efforts, but... well I just
can't believe we could develop a FireWire Audio interface and
software/drivers to run it when exponentially more popular USB audio is
still languishing if not completely ignored.
It's a horse before the carriage issue, the support will need to be
there before $$$ is invested in hardware, it's like designing and
building a car from scratch with no road to drive it on.
