That seems dubious. How many bits do you need? 18? 20? 22?
What sample rate is the minimum required for perfect sound?

I just report what I find. For perfect sound, you need more than 44.1
kHz sample frequency, as the human ear can be affected by frequencies
higher than are consciously audible or available at that sample frequency.

I was, however, using a different ADC and analogue chain for playing
back the CD.

I'm not convinced by that argument for a purely replay medium. For signal
processing you will need ideally higher sampling rates.

To e-mail, change noise into sound.

That depends on who you ask from what i can tell. as the samples go up
accuracy drops.
