What Is Clipping in Audio — Causes and How to Fix It

Clipping is one of the most common forms of distortion that beginners and experienced musicians alike run into. Let's break down what it is, where it comes from, how to hear it, and how to keep it out of your final track.

What is clipping

Any sound is a waveform: a series of amplitude values over time. Every system, analog or digital, has a loudness ceiling it can carry. Clipping happens when the signal tries to exceed that ceiling: the peaks of the wave don't fit and get chopped into a flat horizontal line.

In digital audio the ceiling is 0 dBFS. Anything that should have been louder becomes a flat plateau. The waveform goes from smooth to angular — and, to the ear, that angularity is no longer the original sound but added harmonics.

Where the distortion comes from

A chopped waveform peak is mathematically equivalent to adding a swarm of new frequencies — harmonics that weren't in the original. Those are what give you the crackle, fuzz, and grit. The harder the clip, the more parasitic harmonics and the more audible the distortion.

Clipping sounds especially rough on:

• bass and kick — low frequencies carry high energy, so their peaks clip most audibly;
• transients — sharp drum attacks, plucked strings;
• vocals on peak notes.

Types of clipping

• Digital clipping — the signal hits 0 dBFS inside the DAW or on the master bus. The harshest and most unpleasant kind.
• Analog clipping — overdriving a tube or transistor. Sounds softer and is sometimes used deliberately as saturation.
• Intersample clipping (True Peak) — the sneaky one: sample values sit below 0 dBFS, but when the analog waveform is reconstructed, overshoots appear between samples above zero. This is exactly why platforms and standards require not just "peak ≤ 0" but True Peak ≤ −1 dBTP per ITU-R BS.1770-5.

Clipping and limiting are not the same

They're often confused because both keep the signal under the ceiling. The difference is in how they do it.

• Clipping crudely cuts everything above the threshold — instantly and indiscriminately. The result is distortion.
• A limiter "sees" the peak ahead of time (lookahead), gently reduces it with adjustable attack and release and a soft knee. The waveform is preserved and distortion is almost absent.

More on this distinction in Clipping vs. Limiting. In short: a limiter is controlled restraint, clipping is an uncontrolled break in the waveform.

How to tell if a track is clipping

1. Visually. Look at the waveform: flat, chopped peaks are a sure sign.
2. On the meter. Check peak and True Peak levels. If peaks slam into 0 dBFS, the clipping risk is high. Drop the file into the free LUFS analyzer and read the True Peak: per ITU-R BS.1770-5 the safe target is ≤ −1 dBTP.
3. By crest factor. Crest factor is the gap between peak and average (RMS) level. Lively, un-squashed material sits around 14 dB; when it drops toward ~9 dB and the LRA is crushed near zero, that's the signature of a "brick wall" — the material is already over-compressed, and clipping is especially likely.
4. By LUFS and dynamics. Integrated LUFS alongside LRA shows whether you chased loudness at the cost of dynamics — pushing for loudness is a direct path to clipping.
5. By ear. Harshness and crackle specifically on the loudest moments, gone in the quiet parts, is the classic picture of clipping.

How to fix and how to prevent clipping

The best strategy is prevention:

• Mix with peak headroom: keep the master bus around −6…−3 dBFS and don't slap a limiter on it "for loudness."
• Don't chase maximum loudness in the DAW — platforms will just turn it back down with loudness normalization anyway.
• At the final master, cap the output with a real limiter targeting True Peak ≤ −1 dBTP, not a hard chop.

If clipping is already in the file: the clipped information can't be fully restored, but a declipper can reconstruct the peak shapes and smooth the distortion. Similar logic in our piece on recovering over-compressed material: what a limiter or clipper cut off can't be brought back exactly, but the sense of impact and cleanliness can be partly restored.

How to remove the clipping risk in Magic Master — step by step

Online mastering in Magic Master builds the output so that crude clipping never appears on it. Step by step:

1. Upload your track in the browser — WAV, FLAC, or MP3, no DAW and no plugins to install.
2. Pick a preset or platform target. There are 23 presets (17 music genres, speech/podcast, character presets, and AI Unlimiter) and 16 LUFS targets for platforms. For an already-loud, overloaded source, AI Unlimiter — a mode for recovering over-compressed material — is a good fit.
3. What the chain does. Processing runs in 32-bit float, where the signal can briefly exceed 0 dBFS with no loss. Multiband M/S dynamics on Linkwitz-Riley crossovers even out energy across bands, and a final limiter with True Peak control per ITU-R BS.1770-5 gently brings the output to a safe level (≤ −1 dBTP by default) — with no crude chopping of the waveform.
4. Download the result as WAV, MP3, or FLAC. The final track doesn't crackle on peaks and passes streaming-platform checks.

To be honest: if clipping is already baked into the input file, the output limiter won't create new peaks, but it can't restore the chopped information — a declipper only softens the distortion that's already there. That's why prevention at the mix stage beats any post-processing.

In short

• Clipping is the chopping of waveform peaks under overload, generating distortion.
• It's most audible on bass, drums, and transients.
• It differs from limiting: clipping breaks the waveform, a limiter holds it smoothly.
• Check it via the waveform, peak level, and True Peak.
• The best cure is prevention: peak headroom and a limiter targeting True Peak ≤ −1 dBTP.
