01Overview

L2 Ultramaximizer is a limiter from Waves built around level maximization and high-resolution processing. It works on stereo signals, so it fits buses, mix outputs and mastering chains rather than individual tracks. Look-ahead limiting is designed to prevent overshoot while keeping attack fast. Release can be set manually or handled by the plugin's Auto-Release Control, which responds to the program's dynamics. The interface is kept to a small set of controls, and output dithering options are included for converting to lower bit depths.

Limiting Character and Release Control

The L2 uses look-ahead processing, which lets the limiter react before a peak arrives. According to Waves, this gives an overshoot-free response and fast attack.

Release can be chosen as Manual or as ARC (Auto-Release Control). ARC is described as responding sensitively to dynamics, so the release adjusts with the material instead of staying fixed. Manual mode gives you direct control when you want a set release time.

Mastering and Bus Workflow

Because the L2 is stereo-only, it is intended for bus and master positions, where a single stereo signal passes through. The control set is simplified to keep the workflow fast.

For delivery, the output dithering and noise-shaping options help when converting to lower bit depths. The plugin uses 48-bit, double-precision math internally, and its IDR (Increased Digital Resolution) stage handles bit re-quantization with dithering.

Low latency makes the L2 suitable for live sound and tracking as well as offline mastering.

05FAQ

Questions, answered

What formats and operating systems does the L2 Ultramaximizer support?

The L2 Ultramaximizer is available in VST2, AU and AAX formats. It runs on Windows and macOS.

What is the difference between Manual and ARC release?

Manual release lets you set the release time yourself. ARC (Auto-Release Control) adjusts release automatically and responds sensitively to the dynamics of the material.
