Waves is proud to introduce the L4 Ultramaximizer, the next evolution in peak limiting designed to deliver maximum loudness without sacrificing dynamics. Building on the legacy of the L1 and L2, which defined the sound of the ‘90s and 2000s, the L4 brings modern production needs into focus.
Music today features heavier low end, sharper transients, and wider dynamic ranges. Artists and producers want more than sheer loudness – they need flexibility to shape their sound, balance, and genre-specific character. The L4 was designed to meet those demands.

This all-new limiter offers a powerful combination of loudness, control, and versatility:
- Four redesigned limiting algorithms: Modern, Aggressive, Safe, Smooth, plus a bonus L2 mode for classic character
- Adaptive Clipping & Release controls: Shape the color and impact of transients
- Upward compression: Add density and loudness to softer sections of your mix
- Ultra-low latency: Seamless integration into any session
- LUFS metering: Ensure your track is optimized for streaming
- Two interface modes: Graph and Classic
- Additional features: True Peak limiting, Upsampling, Stereo Link, Dithering, Delta Control, and Gain Matching
With the L4, producers can achieve the perfect balance of punch, clarity, and presence in every track, while maintaining the dynamics that make music feel alive.
