Default Question about Digital vs. Analog

If the clipping in an ADC happens after the anti-alias filter (ie
actual numeric digital clipping), you are in trouble, because you now
have high frequency products that are not filtered away, but are right
there and are going to produce alias frequencies in the audio band.
They won't be harmonically related as analogue clipping would be, but
they will instead be dissonant. You really don't want this to happen,
because once they have been produced, there is no DSP capable of
removing them.


Yes, but analogue clipping can produce intermodulation products too.
The effect isn't usually as obvious, but it can be pretty bad.

Still... maybe it's the cool sound that he's looking for on his guitar.
You never know until you try it.
