Why dual limiting?
Clamp
Control the limiter stage to hold peaks in place.
Release
Set how quickly the CLAMP limiter recovers after controlling peaks.
Warm
Add subtle analogue-style glue, body and smoother tone.
Shortcuts
Finally, shortcuts inside a plugin. Move through your session faster.
CPU friendly
Built for big sessions, keeping things smooth even when the plugin count gets ridiculous.
The various flavours you can impart before it gets limited mean this has so many more uses than first meets the eye: kick drums, drum buses, keys and BV stacks.
Sounds different than my typical digital limiter: thicker and very punchy. In fact it enhances the bass punch when it reduces peaks, giving your signal an analog feel.
I am soooooo blown away by all of the fedDSP plugs I've added to my arsenal. Your plugs sound insane, warmth and depth for days! I am FULLY IN with fedDSP, straight fire!

FAQ
leONE is a dual-stage limiter designed for creative loudness maximisation and reliable peak control. It combines a colour stage, independent high-pass and low-pass filters, a primary limiter called CLAMP, and a final bypassable safety limiter.
Release changes how fast the limiter lets go after gain reduction. Slower settings recover smoothly for natural, transparent limiting. Ultra-fast settings can create intermodulation distortion on purpose, effectively turning the limiter into an additional saturation stage for extra aggression and density.
