Limiter

A limiter is a compressor with an effectively absolute ceiling, guaranteeing audio never exceeds a set peak level — the last safety device before export.

Mastering chains end with a limiter set just under full scale (commonly −1 dBFS true peak) so nothing downstream clips. Pushed hard, limiting trades dynamics for loudness — the historical 'loudness war' — which streaming loudness normalization has made pointless.

What is Limiter?

A limiter is a compressor with an effectively absolute ceiling, guaranteeing audio never exceeds a set peak level — the last safety device before export.

Why does Limiter matter?

Mastering chains end with a limiter set just under full scale (commonly −1 dBFS true peak) so nothing downstream clips. Pushed hard, limiting trades dynamics for loudness — the historical 'loudness war' — which streaming loudness normalization has made pointless.
