It's easier to upgrade than downgrade! ... Ok. ****** I then propose that this project (for the moment) consentrates on the analog and ad/da part. I.e.: . design a 16bit 44.1/48kHz, line-in block . design a 16bit 44.1/48kHz, line-out block . design a 24bit 192kHz, line-in block . design a 24bit 192kHz, line-out block All with spi, without any consideration about multichannel, usb/ ethernet/whatever -- do the analog part good, then we can use it together with "any" cpucard. ****** Would that be something which could move this project forward ? In meantime while we are working on this, the thoughts about processor, usb/adat/firewire/ethernet etc. may have its time to mature. Those of you more interested about other parts of a future system can work out thoose details so that they are clear when the analog/ad/da blocks matures.
