Does clipping noise colour the spectrum

Clipping is a non-linear operation and it introduces new frequencies, so it will change the spectrum's shape.

What is noise clipping?

Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its power rating.

What is the spectrum of white noise?

White noise refers to noise that contains all of the frequencies across the audible sound spectrum, which are those in the range of 20–20,000 Hertz (Hz) .

Is clipping a harmonic distortion?

This is the key difference between clipping and harmonic distortion—while clipping indiscriminately hacks away at anything that exceeds an amplitude level, harmonic distortion adds frequency content in a way that's musically meaningful.

How do you know if a signal is clipped?

Clipping can be detected by viewing the signal (on an oscilloscope, for example), and observing that the tops and bottoms of waves aren't smooth anymore.
