One other idea would be to use a separate A/D convertor and audio
interface

Sounds good until you realise the A/D has to talk to the interface, and
that
part of the technology can change too unfortunately. I wonder if the ADAT
interface used on many multi-track A/D's will outlast USB for example. I
wouldn't want to bet on it.

There are AES and IEC standards for digital interfacing that will help
here. They won't last forever, but will probably be of value for as long
as you want to use the hardware. ADAT optical isn't one of them though
stereo through Toslink optical is covered. AES50 covers multichannel audio
using Ethernet hardware.

Right, but that severely limits the choice of affordable hardware at
present.


USB is a computer communication protocol which is used to send data
between an A/D converter to a computer but isn't really applicable to
passing data from an A/D converter to a computer interface.

But my reply was to the suggestion it would be cheaper to buy a seperate
interface and converter so only one would have to change when standards do.
I'm still unconvinced at this point in time. And unlike firewire, I'm
betting on USB ports for a while longer at least.
