L4 Ultramaximizer

L4 Ultramaximizer is Waves’ adaptive limiter built for modern music, where loudness alone isn’t enough. It delivers competitive levels for streaming while preserving musicality: more low end, more transient punch, and more life. Choose from five unique limiting algorithms—Modern, Aggressive, Smooth, Safe, and L2—plus adaptive clipping and release controls, upward compression, and true peak limiting with ultra-low latency. A gain-match button and LUFS metering help you compare before and after without fooling your ears, while oversampling and stereo link ensure clean, reliable results. Two GUI views (graph and classic) suit different workflows. Whether you’re mastering a bass-heavy track, adding punch to drums, or taming peaks on a full mix, L4 enhances rather than squashes. It suits hobby producers and engineers working in FL Studio, Ableton, or Logic who want loud, dynamic masters that translate on any system.
