Tone Projects: UNI-L MASTER LIMITER 1.0.0r1 is Here! [Windows]
Tone Projects UNI-L is a state-of-the-art master limiter for Windows — co-developed with mastering engineer Bob Macc and endorsed by some of the most decorated mastering engineers in the world including multiple GRAMMY-winning engineers. Released in May 2026 as version 1.0.0, UNI-L is built around a unique approach that merges the tonal integrity of wideband limiting with multiband detection — achieving clean, natural loudness even at high gain without the crush. A sophisticated adaptive lookahead and release algorithm continuously responds to complex audio material, while the dual-stage limiting and integrated clipping can be precisely balanced for exceptional control over every stage. UNI-L lets you push loudness as far as you need — while keeping the sonics pure and the music alive. Available as VST3 and AAX on Windows with a free trial available.

Key Features
Frequency-Aware Wideband Limiting
A wideband limiter driven by a unique multiband detection path — frequency-aware limiting without tonal shifts or destructive crossovers. Adaptive lookahead and auto-release adjust continuously to spectral and dynamic content on Windows.
Dual-Stage Limiting + Clipper
A slow limiter for average dynamics, a fast limiter for peaks, and a tightly integrated clipper all working in concert. Focus release on low frequencies, clip just the highs — shape loudness, dynamics, and transients with exceptional precision.
Transient Override
Flexible transient detection gives musically important transients special treatment — clip just the snare for punch while handling the rest of the signal more gently. Separate lookahead times for transients and the main signal.
32x Linear-Phase Oversampling
Pristine clipping with up to 32x linear-phase oversampling — bit-transparent pass-through and no post-filtering overs for maximum sonic integrity on Windows.
Quick Start System
Carefully tuned presets with a single macro slider controlling the entire limiter for instant results. See underlying parameters change as you move the macro — great results in seconds, full control always available on Windows.
Full Creative Control
True Peak mode, EBU R128 LUFS metering, flexible stereo linking, low-band stereo linking, detailed release shaping, Clip Attack, Fast Above and Clip Above crossovers, Low Split, Delta and Gain Match monitoring — complete mastering toolkit.

What GRAMMY-Winning Engineers Say
“Uni-L is probably one of the most flexible and versatile limiters on the market today. The level of reshaping and tone control you can achieve is incredible — it gives you the power to push loudness while still maintaining musicality, depth, and character in a way that feels truly unique.”
GRAMMY-winning Mixing and Mastering Engineer — Skrillex, Drake, Diplo, Madonna, Daft Punk
“With so many limiters claiming to be the best, Uni-L is definitively the best new limiter out there. It gives me the low end, punch, transient shaping and flexibility to inject even more life and energy in my masters.”
2x GRAMMY and Multiple Platinum Winning Mastering Engineer
“Uni-L is more full featured and versatile than any other digital limiter I’ve used. It can be subtle and transparent, or aggressive when needed. In all cases, I was able to obtain a louder master with fewer artifacts than with other limiters that I’ve worked with.”
GRAMMY-winning Mastering Engineer — Author of “Mastering Audio”
“Uni-L has reshaped how I approach limiting. It’s transparent in a way that retains transients without smearing, density increases without sounding compressed, and there’s a gracefulness that feels intentional rather than accidental. It’s the first limiter I reach for, and most of the time it’s the only one.”
GRAMMY-nominated Mastering Engineer — Jon Batiste, Dan Deacon, Blondie, Ice Cube
“Uni-L is the most powerful limiter available and it’s a long way to number two. Mix contours and transient detail survive as the gain goes up. Turns out you can have it all.”

What makes UNI-L different from other master limiters on Windows? ▾
UNI-L’s core differentiator is its frequency-aware wideband limiting architecture — a wideband limiter driven by a unique multiband detection path that achieves frequency-aware limiting without the tonal shifts or destructive crossovers of traditional multiband limiters. This is combined with a dual-stage limiter and integrated clipper that can be independently controlled — including features like Transient Override (separate lookahead for transients), Clip Attack (timing-based clipping to preserve transients), Fast Above and Clip Above crossovers for frequency-specific control, and a Low Split for reduced distortion. The result is a limiter with exceptional transparency at high loudness levels — praised by GRAMMY-winning engineers for preserving transient detail, mix contour, and musical character even at aggressive gain reduction settings.
Is there a free trial of UNI-L for Windows? ▾
Yes — Tone Projects offers a free trial of UNI-L for Windows. The trial can be downloaded directly from toneprojects.com and gives you full access to the plugin so you can evaluate it in your own mastering sessions before purchasing.
