Tone Projects Uni-L – True Peak Mastering Limiter, Now 73% Off

The last plugin in your mastering chain has one unforgivable job: let nothing clip, anywhere, ever — including the overshoots that only appear after a streaming encoder gets hold of your file. Tone Projects Uni-L was built around exactly that responsibility, and today it sits on the board at $39.99 instead of $149. That is 73% off a professional true peak limiter, the kind of specialist tool that normally asks mastering money, here priced like a utility. If your masters are still riding a stock limiter, this is the upgrade shouting your name.

Loud, Without the Usual Damage

Most limiters sell volume and quietly charge you transients for it. Uni-L’s reputation rests on the opposite trade: engineers reach for it because it focuses on transparency and musicality instead of simply making mixes louder. It is designed to preserve transients while controlling peaks naturally, holding competitive loudness while keeping clarity, punch, stereo width, dynamic balance, low-end control and high-frequency detail intact. Push it for a subtle final polish or lean on it for aggressive loudness processing — the character of the mix survives either way, which is precisely what separates a mastering limiter from a loudness hammer.

Multiple Limiting Modes, One Workflow

Rather than one fixed behaviour, Uni-L offers a collection of limiting styles so the engineer chooses the tool’s temperament per record: transparent limiting when the mix must not change colour, modern loudness processing for commercial targets, dynamic preservation when the performance breathes, punch enhancement when the drums need their attack defended, peak protection for safety-critical delivery, and streaming optimization for platform-ready files. That flexibility means the same plugin serves an EDM master chasing impact, a rock record protecting its snare, a hip-hop mix guarding its low end, and a cinematic score that must stay elegant at any volume.

Built for the Streaming Era’s Rules

Modern delivery is unforgiving: masters are prepared for Spotify, Apple Music, YouTube and other streaming platforms, each transcoding your file and each capable of exposing inter-sample peaks your DAW meter never showed you. True peak protection exists for exactly this. Uni-L helps you increase perceived loudness, prevent clipping, control transient peaks, meet streaming platform standards and keep final masters consistent from release to release. Put it where it belongs — as the final processor in the mastering chain, or on the mix bus when a production needs its ceiling defined early — and the guesswork leaves the room.

Meters You Can Trust, Controls That Stay Out of the Way

The interface is designed to simplify professional mastering tasks while keeping advanced control available: easy loudness adjustment, visual gain reduction monitoring and real-time peak metering keep you informed without burying the music under data. You see what the limiter is doing, you hear that it is barely doing anything at all, and you move on to the next record. That speed matters in commercial work, where consistency across an album or a catalogue is the actual product being sold.

Equally at Home Before the Master

Although Uni-L was built for the final stage, plenty of engineers also run it on the mix bus, where defining the ceiling early keeps every later decision honest, and broadcast work leans on its true peak discipline for delivery that cannot afford surprises. The through-line is consistency: commercial releases live or die on whether a catalogue sounds like one artist and one standard, record after record, and a limiter this transparent makes that standard repeatable whether the material is EDM, pop, rock, hip-hop or a cinematic score. Set the behaviour, trust the meters, print the master — the tool’s job is to make the loudest decision in your chain also the calmest one.

The Deal

Run the numbers: $149 down to $39.99, 73% off, $109.01 saved on the final link of your mastering chain. This is the cheapest step up from a stock limiter most producers will ever be offered, and it is a step up in the exact place listeners hear quality — the last processor before the world does. Board it now, set your ceiling once, and stop wondering what the encoder will do to your masters.
