Clipping: What It Means in Music Production
Clipping occurs when an audio signal exceeds the maximum level a system can reproduce, causing the waveform to be flattened at the ceiling and introducing harsh, non-musical distortion. In digital audio, clipping happens when the signal exceeds 0 dBFS.
Full Explanation
When a signal is clipped, the peaks of the waveform that exceed the maximum level are literally cut off, creating a flat-topped waveform. This introduces harmonic and intermodulation distortion that sounds harsh and unpleasant. The severity depends on how far and how often the signal exceeds the ceiling: a single sample over 0 dBFS may be inaudible, but sustained clipping is immediately noticeable as crackle, buzz, or harshness.
Hard clipping happens instantaneously at the ceiling and creates the harshest distortion. Soft clipping applies a gradual curve as the signal approaches the ceiling, creating a more musical form of saturation. Many analog emulation plugins and console models use soft clipping by design, which is why analog-style processing is often described as having a warm, forgiving character.
Intentional clipping (or "clipping" via a hard clipper plugin) is sometimes used as a mixing technique to shave off transient peaks before a limiter, allowing for louder masters with less limiting artifacts. This is different from accidental clipping caused by poor gain staging.
In Electronic Music
In electronic music, clipping is both a hazard and a tool. Accidental clipping from poor gain staging sounds terrible and must be avoided. But intentional soft clipping on drum buses, bass channels, or the master bus is a common technique in genres like techno and dubstep to add density and controlled saturation. Some producers use a hard clipper before the final limiter to handle transient peaks, allowing 1-2 dB of louder mastering with fewer pumping artifacts.
