David A.Roth:
I have another question/concern. When the sound files
are extracted as WAV,
most of them will be 30k mono samples. If I wanted to also burn an audio CD
of some of these WAV files, wouldn't they be converted to 44.1K stereo? I'm
using Toast and Jam on the Mac.
Depending on your CD burning application, you might have to do this
manually beforehand.
It's been years since I even thought about this,
but would allowing the
translation of it from 30K to 44.1K introduce some artifacts into the
sound?
This is quite likely. Sample rate conversion is a surprisingly difficult
thing to get right, and there are fairly well documented cases of very
expensive, supposedly "professional" software if not quite making a right
mess of it, at least not doing it as well as possible.
Must an audio CD be at 44.1k stereo because of its
standard?
Yes.
Perhaps I would be better off to burn them to CD-ROM
in ISO 9660 format
only for portability and long term archive purposes?
If you wanted to keep reusing the samples, that would be far better than
recording them as an audio CD. As for long-term archiving, who knows
how reliable CD-R media really is? I'd certainly still burn them to CD-R
or DVD-R, but I'd also keep multiple copies. 200 floppies' worth of
samples actually won't take up that much space on modern hard drives.
You could even fit them all on a USB key, unless my arithmetic is right
out.
Cheers,
Bernie
