What it is

The L4 Ultramaximizer is an adaptive peak limiter from Waves designed for modern music production. It offers five distinct limiting algorithms - Modern, Aggressive, Smooth, Safe, and the classic L2 mode - to suit a range of styles and loudness targets. True Peak limiting, LUFS metering, and oversampling support make it a technically complete mastering tool.

Who it's for

Producers and mixing/mastering engineers who need competitive streaming loudness without sacrificing low-end clarity, transient punch, or dynamic character.

Key features

• Five limiting algorithms let you dial in anything from transparent glue to hard-hitting loudness
• Adaptive clipping and release controls give you precise command over how peaks are handled
• Upward compression adds body and presence without pushing the ceiling down
• Dual interface modes - graph and classic - let you work visually or with a streamlined layout
