Digital clipping is incredibly difficult, if not impossible to do in a 32-bit floating point system which is what the majority of DAWs are these days. My point is that almost all clipping you'll experience is from slammed levels being output at the D/A which then, in turn, clips the analogue section. Visa versa for the A/D end.
Try it. I dare anyone here to try and accomplish digital clipping in any 32-bit FP DAW.
And for the record, digital clipping is a lot easier to fix than analogue clipping combined with saturation distortion. If you've ever used the pencil tool in Wavelab, you can actually draw a smoother waveform to lessen its effects. I have successfully "rounded out" clipped waveforms and the result was unnoticeable.
Just saying.
