Clipping

What Is Clipping?

Clipping happens when an audio signal is pushed too hard. Think of a sound wave as a smooth, rolling hill. When the sound gets too loud, it hits a ceiling. The top of the hill gets chopped off and becomes flat. This flat part is called clipping. It changes the shape of the sound wave. This change makes the sound harsh and rough.

What Does Clipping Sound Like?

Clipping sounds like a buzz or a crunch. It is usually not a pleasant sound. If you listen to a singer and their voice clips, it will sound fuzzy and scratchy on the loud notes. It sounds like a broken speaker.

When a drum sound clips, it loses its punch and sounds flat and messy. It is a harsh noise that hurts your ears if it is too loud.

How Do You Prevent Clipping When Recording?

The best way to stop clipping is to turn down the gain before you record. This is called leaving headroom.

When you set up a microphone, ask the musician to play their loudest part. Watch the volume meter on your screen. Set the gain so that the signal is well below the red zone. It is always better to record a little quiet rather than risk clipping.

You can easily make a quiet recording louder later. But if you record too loud and it clips, it is very hard to fix.

Does Clipping Happen When a Sound Is Recorded Or When It Is Played Back?

The answer is both. Clipping can happen when you record a sound, and it can also happen when you play it back.

When you record a song, the microphone might get a signal that is too loud for it to handle. This means the sound clips before it even reaches the computer. The file itself is saved with the chopped sound wave. Even if you play it back quietly, it will still sound clipped.

On the other hand, the recording might be perfectly clean. But if you turn your speakers or headphones up way too loud, those devices will hit their limit. The speaker will clip the sound as it plays it. This means the file is not clipped, but the speaker is creating the clipping. If you turn the speaker down, the sound will be clean again.

How Do You Fix a Clipped Audio File?

Fixing a clipped file is very difficult. Once the top of the sound wave is chopped off, that piece of sound is gone forever. You cannot put it back.

However, there are some computer programs that can help. These tools guess what the missing part of the wave looked like. They try to draw it back in. This can make the sound a little better. It takes away some of the harsh fuzz. But it will never sound as good as a clean recording. The best fix is to just record the part again.
