The L3-16 Multimaximizer Native, from Waves, is a plug-in that performs multi-band peak limiting. The plug-in divides the audio source into sixteen variable bands and utilizes a patent-pending "Peak Limiting Mixer" (PLMixer) engine.
Unlike most wide band limiters, the L3-16 uses linear phase crossover filters to divide the audio spectrum into the sixteen bands. The PLMixer then uses psychoacoustic criteria to intelligently decide how much attenuation to apply to each band so that all available headroom is used.
The result is that inter-modulation is minimized and overall loudness is maximized, while brick-wall limiting is still maintained. Also included in the package are the L3 Multimaximizer and Ultramaximizer, and the low latency L3LL Multimaximizer and Ultramaximizer versions.
