The L3 Peak Limiter is a sophisticated mastering tool comprised of two plug-ins: the Multimaximizer and the Ultramaximizer. It utilizes a unique Peak Limiting Mixer (PLMixer) engine that separates the audio spectrum into five linear phase bands, ensuring minimal inter-modulation and maximum loudness while maintaining brick-wall limiting. This approach differs from traditional wide band and multi-band limiters by intelligently controlling gain across bands without requiring an additional wide band limiter to catch overshoots.

Users can shape the tonal character of their audio through the L3's Priority control, which adjusts the relative limiting of each band, as well as a 12dB boost or cut per band that functions like a Linear Phase EQ ahead of the limiting stage. The plug-in features selectable crossover points and offers transparent processing with the option to emulate vintage limiter characteristics via controls such as Separation and Master Release. These features allow the L3 to deliver a broad range of sonic textures while preserving clarity and punch.

Completing the L3's capabilities is an integrated dithering and noise shaping section, ensuring high-quality sound after quantization. Available as the full-featured Multimaximizer or the more streamlined Ultramaximizer, the L3 provides precise loudness control and tonal flexibility that make it suitable as an all-in-one mastering processor. Its combination of transparency, tonal shaping, and peak limiting makes it a reliable choice for achieving polished, professional final mixes.
