What it is

L4 Ultramaximizer is Waves' newest adaptive peak limiter and loudness maximizer, the fourth generation of the brand's long-running L-Series that started with the original L1 and L2 Ultramaximizers. It runs a real-time adaptive engine that reads transient density and crest factor to adjust attack, release, and lookahead on the fly, aiming for competitive streaming-ready loudness without flattening the mix. A dedicated L2 mode recreates the sound of the original L2 limiter for anyone who wants that classic character inside the newer plugin.

Who it's for

Mixing and mastering engineers who need a final-stage limiter for streaming-ready masters, plus producers who want more punch and density on a mix bus without resorting to a brickwall sound. Also a fit for anyone who grew up on the original L2 Ultramaximizer and wants that same tone with modern loudness tools built around it.

Key features

• Five limiting algorithms - Modern, Aggressive, Smooth, Safe, and a dedicated L2 mode that reproduces the original L2 Ultramaximizer's sound
• True Peak limiting with oversampling keeps masters within streaming platform peak specs
• Built-in LUFS metering and a Gain-Match function let you A/B processed and unprocessed audio at matched loudness
• Upward Compression, inspired by Waves MV2, adds density to quieter passages without pushing peak levels any higher
