Product details
Every master ends at the limiter, and every limiter leaves a fingerprint. The question is whether that fingerprint is musical or destructive. Tone Projects Uni-L is engineered for the former: a true peak limiter that pursues loudness through transparency — preserving transients, punch and depth while keeping peaks exactly where streaming platforms and broadcast standards require.

Transparency as a design discipline
Limiting is inherently violent — it is gain reduction at the extreme. Uni-L’s achievement is making that violence inaudible: transients survive, stereo depth stays intact, and the low end keeps its weight. Instead of the flattened, fatiguing sound of aggressive limiting, you get masters that feel loud because they are dense and controlled, not because they have been crushed. For acoustic music, dynamic genres and anything where musicality matters, this is the difference between a master you are proud of and one you apologize for.
Modes for every mastering scenario
One limiter character cannot serve every master. Uni-L’s multiple limiting modes cover the realistic range: transparent peak control for delicate material, modern loudness modes for competitive pop and electronic releases, dynamic preservation for when the performance’s natural ebb and flow must survive, and strict peak protection for broadcast delivery. Switch modes instead of switching plugins — your mastering chain stays consistent and your recall stays simple.
Streaming-era compliance
Modern delivery is a technical gauntlet: true peak limits, loudness normalization, codec transcoding. A master that clips on upload gets turned down and sounds worse than a properly limited one. Uni-L is built for this reality — true peak limiting that survives conversion to Spotify, Apple Music, YouTube and broadcast chains, with loudness optimization that keeps your music competitive after normalization does its work. Keep a final Uni-L instance on your monitoring chain while mastering and you will hear exactly what the platforms will do to your dynamics.

Why creators buy from AudioTools
AudioTools is built for producers and creators who want their releases to sound professional everywhere.

At 73% off, Uni-L is the final 2% your masters have been missing — browse the shop for more, or explore the Mix & Master Plugins category for finishing tools.
Dialing it in
Start with the transparent mode and increase gain reduction until you hear the limiter working, then back off slightly — that is your loudness ceiling for the track. A/B against your unmastered mix at matched loudness to make sure you are gaining punch, not just volume. For streaming releases, verify true peak readings stay within platform specs before export. These habits, combined with Uni-L’s transparency, produce masters that sound intentional rather than squeezed.
Frequently asked questions
Why does true peak matter for streaming?
Codecs and sample-rate conversion create inter-sample peaks above 0 dBFS — true peak limiting catches what sample-peak meters miss, preventing distortion on platforms.
Will it work for my genre?
The multiple modes cover everything from transparent acoustic mastering to aggressive electronic loudness.
Can I use it on the mix bus too?
Yes — Uni-L works for mix bus peak control and loudness as well as final mastering.
Does it color the sound?
Transparency is the design goal; the limiter aims to be inaudible, preserving your mix’s character.
How do I receive it?
A secure download link is sent to your email, usually within minutes of checkout.
