In the ’90s and 2000s, L1 and L2 were loudness. From Red Hot Chili Peppers to Metallica to Timbaland, countless iconic records ran through them – that was how you stood out. But loudness was yesterday’s battle.

Today, music needs more. And L4 delivers.

An adaptive limiter designed for modern music, L4 delivers not just (super) competitive levels for streaming, but also musicality:

More low end. More transient punch. More life.

Today’s sound is deeper. Bigger. More dynamic. Artists grab attention with more than just volume – with nuance, impact and feel. Limiters need to enhance music, not just squash it. L4 adds 5 unique limiting algorithms, adaptive Clipping & Release controls, Upward compression, True Peak, and much more.

5 Unique Limiting Algorithms

Every song is different. We worked hard to create a palette of limiter algorithms to suit whatever you’re working on.

Modern, Aggressive, Smooth, Safe, and of course, we gave you the legendary L2 sound as well.

Adaptive Clipper & Release

We wanted to keep things simple. The Clipping and Release settings are content-dependent – the plugin sets them based on your track.

You then control the relative level of each, as you hear how they’re affecting the transient impact and feel.

Upward Compression

Inspired by the classic MV2 plugin, this module is incredible for bringing forward quieter passages and adding density.

Used together with appropriate limiter settings, you’ll get more loudness AND more dynamic impact.

Ultra-Low Latency

L4 is a workhorse. You can track through it, mix into it, and master heavy sessions back-to-back.

Even use it live – with LV1, SuperRack SoundGrid, SuperRack Performer, or Ableton live sessions.

LUFS Metering

Prepare your track for streaming.

With short-term and long-term LUFS metering, you’ll have accurate levels while working, allowing you to optimize your songs for different streaming services.

Two GUI Views

For those who like to see exactly what’s being limited, you have the ‘Graphical’ view of L4.

For those who like to work old school and mix with your ears, you have the classic view of L4, inspired by the L2 design.
