PC still playing Amiga catchup

[ejstans]

As I said numerous times, what difference does it make if I sample audio at 22Khz or 44Khz-- not much but logically there's a difference if you know there can be frequency components that won't get captured at 22Khz.

What exactly is this difference?

The highest audio  tone that can be captured is very slightly less than one-half the sampling rate of an analog-to-digital convertor.
So the 22khz rate will not save sounds much above 10kHz and will result in music missing the highest harmonics,whereas 44(actually 44.1kHz) sampling will save all the sounds even the best human ears can hear,that is up to 22kHz.Most people  lose the hearing of higher pitched sounds as the person ages,especially if exposed to lots of loud sounds.

Bzzt, but thanks for playing even though the question was addressed to a different person...
