While a PC won't make a good scope, it certainly does a superb job as
a distortion analyzer, sig gen, and SNR meter.

For most audio purposes, a PC with a 24/96 or 24/192 sound card is a "good
enough": scope. IME a 22 KHz scope (44 KHz sampling) is a bit lame, but a
100 KHz scope (200 KHz sampling) can get a lot of jobs done.

I have found that a
good scope along with some software and a good sound card, I can
measure the specs of nearly any amp or preamp made and do it with
greater accuracy.

You can even do a complete tech test of an amp or preamp nearly hands-off
with the freebie Audio Rightmark software.
