When Should I Use An Audio Limiter?

By Kevin Graham

When it comes to your video’s final mix, its overall loudness level is one of the most important things. Whether you’re delivering for web or broadcast, there will likely be at least some loudness guidelines you’ll want to follow.

An audio limiter is a great tool to help you control your video’s loudness.

Basically, an audio limiter is a compressor with an extreme ratio setting that is used to not allow any audio to exceed a certain volume.

Most commonly, after the limiter is applied, the input gain is then adjusted to make your video louder, without any clipping.

You may be familiar with the music production terms mixing and mastering. In the mastering stage of music production, a limiter is the most important effect. This is what ensures that the loudness level of the song will match everything else on the radio and on streaming services.

Of course, there is a limit (no pun intended) to how far you can push this before you start to hear distortion, especially if your mix has lots of low end.

But you can get a much louder video this way, without overdoing it.

You always want to get your initial mix as close to your target volume as possible. But when you’re finishing a video and preparing to send it out to the world, a limiter is an essential audio tool to fine-tune your video’s loudness to the perfect level.
