going there.
Nah, i'm not depressed. I expected something like that though not quite as
high.
From my POV a more interesting idea would be to do an external sound
device, probably 1394 based since that will work for more people.
Please remember that a PCI card is almost useless for laptop users
unless we're trying to put this into a cardbus formal also. That adds
money.
If it was 1394 based then you can put a 1394 adapter in your PC for
$20 and then everyone uses the same audio unit. We control how it
works, so we can follow specs or do it in our own standard. You get
the advantage of probably more channels and better SNR, but you do
have to package the unit in a box or some type to be of general use.
Anyway, those are some ideas for you to chew on. Hope I haven't poked
a balloon with a pin here...
No, i find the alternative of a 1394 device completely acceptable, too. But
how much cheaper would it be? I suppose the logic for talking to the 1394 bus
[?? i don't know anything about firewire, except for 1. serial, 2. faster
than USB] can be put into a FPGA again, right?
For the sake of an example, let's choose a stereo full duplex device with
48khz only samplerate, and with medium to good quality AD/DA's. So we got
like 15-30 bucks for the DA/AD's. What's the rest? How expensive is the FPGA
to control all this? What else is needed? Ok, a case mustn't be pretty, so i
suppose anything will do -> 2-3$ :)
