What shall we do with analog audio? Sample at 44.1KHz
/ 16-bit PCM
and call it done?
No! Please! Not for archival purposes! For audio, you
probably could get away with capping it at a few GHz
sample rate - I'm not sure air can carry frequences that high -
Well, maybe
I'm wrong, but "audio" would assume "audible"... as in
you need to be able to hear it. Standards say that would be 20Hz->20KHz, but
I'd say DC->25KHz would
be better...
It would. Certainly go down to the DC. I understand that a small but
decent percentage of the population (mostly children) can hear as high
as 25KHz, and I'd definitely want a good deal of headroom above that.
