Clipping is what happens when a signal is pushed past the highest level a system can handle. The tops of the waveform get chopped flat against that ceiling, which adds new harmonics and makes the sound break up and distort. In the digital world it usually sounds harsh and nasty, and it is one of the most common ways a mix gets spoiled.
This is about clipping on any system, in any DAW, on any interface. The idea is the same whether you are talking about a track, a plugin, the master, or the input of a converter. Levels here are written in dBFS, decibels below the point where digital audio clips.
Clipping is what happens when a signal is pushed past the maximum level a system can handle, so the peaks of the waveform get chopped off flat and the sound distorts. Every part of the signal path has a ceiling, a loudest level it can pass cleanly. When the signal tries to go louder than that, it cannot, so anything that would have risen above the ceiling gets flattened against it instead.
A clean sound swings smoothly up and down. Clipping shears the tops and bottoms off those swings and leaves flat plateaus where the rounded peaks used to be. Those flat edges were not in the original sound, and the sharp corners they create throw off a burst of new high harmonics. That is what you hear as the harsh, broken, crackly edge on a signal that is clipping.
You can usually catch it before you even hear it. Most meters have a clip light or an overload indicator, often a small red mark at the top that lights up and stays lit the moment the signal goes over. On the sound itself, clipping shows up as a crackle, a fuzzy grit, or a broken edge that rides on the loudest peaks and vanishes in the quiet parts. If a meter is showing red and the loud moments sound ragged, that is clipping.
In digital audio the ceiling is 0 dBFS, the loudest level a sample can hold. Push a signal above it and there is nowhere for the peaks to go, so they clip flat. Every level below that is written as a negative number, so a peak at -6 dBFS has 6 dB of room left before it clips. Leaving room below 0 dBFS is called headroom, and it is the single best defence against clipping.
Digital clipping happens when a signal goes over 0 dBFS, the ceiling in digital audio, and it chops the peaks off hard and flat, which almost always sounds harsh and nasty. Analog clipping happens when an analog circuit is driven past its limit, and it tends to round the peaks off more gently, which can sound warm rather than broken.
| Clipping | What happens to the peaks | How it tends to sound |
|---|---|---|
| Digital, over 0 dBFS | Chopped off flat at a hard ceiling, with sharp square corners | Harsh, brittle and nasty, the kind you want to avoid |
| Analog, a circuit pushed hard | Rounded and squeezed down more gradually as it nears the limit | Softer and warmer, and in small amounts can be pleasant |
Digital clipping is abrupt. The signal is fine right up to 0 dBFS and then hits a wall, so the corner it puts on the waveform is sharp and square. Sharp corners are full of high harmonics, and a lot of them land as harsh, unmusical frequencies, so hard digital clipping usually sounds brittle and ugly. There is no softness to it, which is exactly why it is the kind of clipping to keep out of your mixes.
Analog clipping is gentler because a real circuit does not switch off at a hard line. As you push it, it runs out of room gradually and rounds the peaks off, easing them down rather than shearing them flat. That softer corner leans on lower, warmer harmonics, which is why a pushed analog circuit can sound thick and pleasant instead of broken. At that gentle end it starts to overlap with saturation, and our guide on distortion and saturation covers that warmer, on purpose side of the same idea.
You stop unwanted clipping by leaving headroom and keeping your levels sensible, so nothing is ever close enough to the ceiling to hit it. If something is already clipping, the fix is almost always to turn a level down rather than up, until the red goes away.
None of this is fussy. Give yourself a little headroom, feed sensible levels in, and glance at your meters as you go, and unwanted clipping mostly takes care of itself. It is far easier than trying to rescue a signal that has already broken up.
Turning a clipped signal down does not fix it. Once the peaks have been chopped flat, the missing information is gone, so lowering the level afterwards only gives you a quieter version of the same distortion. Clipping is a thing to prevent going in, not repair later, which is why headroom matters more than any plugin you could add at the end.
Yes. Used deliberately and in small amounts, a clipper is a normal mixing and mastering tool. It shaves the very tops off the tallest, shortest peaks in a signal so you can raise the overall level and gain loudness, which is a world away from letting a whole mix clip by accident.
The trick works because the loudest peaks in music are often brief transients, the initial spike of a drum hit for example, that you barely register as loudness even though they eat up your headroom. A clipper trims just those spikes off, gently and on purpose, which frees up room to push the rest of the signal louder. Mastering and mix engineers use clippers exactly this way, often alongside a limiter, to get a track loud without it feeling squashed.
The difference from accidental clipping is control and amount. A clipper is aimed at a few short peaks, in tiny amounts, by choice. Accidental clipping is a whole signal running past the ceiling because the levels were too hot, chopping everything without care. Same underlying behaviour, completely different outcome, because one is measured and one is an overload.
When people say a track is clipping, they nearly always mean the bad kind, an overload where the signal has run past the ceiling and broken up. That is not the same as saturation or distortion, which you add on purpose for colour and warmth, even though the gentle end of clipping shades into them. If you are after character rather than trying to avoid an overload, reach for distortion and saturation, not a signal that is too hot.
Most clipping is a levels problem, and levels problems are easier to dodge than to repair. The less often a signal arrives too hot, the less time you spend chasing red lights, and a lot of that comes down to what you feed in at the start.
The Collection is our three instruments together, ARGISH, SILT and REHEAT, with three separate licence keys. This page is about keeping signals clear of the red, and that job starts easier when the sound going in is already sensible: our instruments output at a clean, controlled level with headroom to spare, so you start well below the ceiling instead of fighting a signal that is already too hot. ARGISH is a self-playing chord synth, SILT is a tape-loop instrument, and REHEAT writes acid lines, and whatever you make with them is yours to release. Each one ships as AU, VST3, AAX and a standalone app on macOS, signed and notarized, and a VST3 on Windows.
