LimitOne

The deal

$149.40 at KVR Marketplace (down from $249). Sale ends June 3, 2026.

What it is

LimitOne is a mastering limiter from Leapwing Audio that replaces the traditional envelope-following approach with a hybrid spectral algorithm. It uses two distinct processors - Pufferfish handles frequency domain adaptive dynamics, and Hedgehog handles time domain transient shaping - giving it a different character from every other limiter on the market. Grammy-winning mastering engineer Bob Katz calls it his favorite mastering limiter.

Who it's for

Mastering engineers who want maximum loudness without the artifacts that come with traditional brick-wall limiting. It also works well for mix bus limiting when you need transparency at high levels.

Key features

• Hybrid spectral algorithm combines frequency and time domain processing for results traditional limiters can't achieve
• Variable balance between soft limiting and hard clipping lets you dial in exactly how transients behave
• True peak control ensures no overshoot on any playback system
• Available in AAX-Native, VST3, and AU formats with native Apple Silicon support
