distortion caused by cutting off the peaks of audio signals. Clipping usually occurs in an amplifier when its input signal is too high or when the volume control is turned up too high. A clipped waveform contains a great deal of harmonic distortion and sounds very rough and harsh. Hard clipping results in very sharp edges on the waveform, producing the maximum amount of high-harmonic content. Soft clipping produces rounded edges of the clipped waveform and is much less grating on the ears and tweeters than hard clipping as it contains much less very high-frequency energy. Different amplifiers produce different clipping effects; tube amps often produce soft clipping. See full codedigital black.
