Huh?
Doesn't resampling involve recreating the analog waveform and slicing it at
a different interval? Except for having no (potentially lossy) travel during

No, it creates a *model* of a waveform. But that's what sound is; a
waveform. There is no other real way to express it. There is no such thing
as a digital sound.
This is because of the fact
I asked,

What counts is that there's still conversion from discrete to continuous and
back to discrete. If, because the
My question, again, is this: isn't resampling equivalent, except for there
being no analog travel in the middle, to DAC+ADC?
no. resampling to a higher sampling rate (eg 32kHz-44.1, or 44.1-48) can
be done with almost no degradation of quality. assuming a sound with no
sound components above

Thank you. Unluckily, the stuff there was way over my head.

that's basically correct. the biggest difference is that whenever you're

Thanks to Peter, Timothy, and Chad for clearing it up for me.

Hello everyone. As most of you may know, 44.1 kHz is the standard
sampling frequency for CD and MD recording. Also note that 32 kHz is
used in satellite and digital radio broadcasts, as well as employed in
long play modes for DAT recorders. We are expanding our business very
soon to include
