The ML4000 is a high-resolution limiter and multi-band dynamics processor designed for music, mastering, post, and live sound. The ML4000 is two plug-ins: ML1 (Master Limiter) and ML4 - (Multi-band Gate, Expander, and Compressor fed into the ML1 mastering limiter).

Perfect Mastering
The Release, Knee, and Mode controls can setup the subjective sound of the limiter. The multi-band dynamics processor can be used to augment or correct the input signal and best prepare it for treatment by the mastering limiter.
Unique EQ
While there is no EQ section in the ML4, the crossovers and the band output gains are the basic controls of a graphic EQ of sorts. The output levels of each band can be altered, and then are recombined in the mastering limiter section.
Use the Real-Time Analyzer to monitor how the frequency spectrum is being affected. The RTA feature is only available for AAX Native, AU, and VST3 plug-in formats.

Multi-Band Compression for Guitars
Although most musical performances need some degree of dynamics, a varying dynamic range can be both a blessing and a curse.
OTT with Multi-Band Expansion
What is OTT, why is it so popular, and most importantly, how do you create it?
Limiter Section
The ML1 mastering limiter uses a flexible brick wall look-ahead design coupled with multiple stages of limiting for superior peak detection.
Simultaneous display of Gate, Expander, and Compressor Dynamic curves in every band in a variety of display modes.
Crossover points are graphically adjustable. A dynamic plot of the input, output, or overall dynamics action can be displayed, and is updated alongside any crossover adjustments.
Multiple real-time metering options. All band metering is shown alongside the band gain sliders.
Knee and Mode
The ML4000 has several Character Mode settings to allow the limiter to respond differently to input signals, while still achieving maximum signal levels that do not exceed the output ceiling.
The expanders in the ML4000 can be set up to be downward or upward expanders. To either reduce or increase signal levels when the input signal falls below the selected threshold.
