Audio Processing Units

Which loudness tool should I use?

The tools share measurements and a similar interface, but suit different ways of working.

Leveler ↗

Keep a vocal or spoken recording at a steadier level.

Set a target and let it ride the gain as the level changes.

Compressor ↗

Shape the dynamics of a vocal, bass part, or mix.

Choose how compression or expansion responds, using loudness or peak detection.

Limiter ↗

Limit output loudness and catch peaks.

Set separate limits for loudness and peaks, with control over the gain response.

Optimizer ↗

Adjust the dynamics of a complete recording.

Analyze the file, reshape its loudness range, then listen and export.

Compressor, Leveler, and Optimizer already include peak limiting. The separate Limiter is for more detailed control over loudness and peak limits.
