The ML4000 from McDSP is a mastering plug-in that consists of two parts. The ML1 is a broadband stereo mastering limiter with multiple stages of limiting for superior peak detection. A continuous knee control allows the ML1 to sound transparent or aggressive.

The ML4 is a multi-band mastering limiter with each band having a gate, expander and compressor. Each band's gate, expander and compressor can be configured separately or linked together. Steep 24dB/octave crossover filters minimize signal leakage into adjacent bands.

The individual plug-ins function in multiple formats, including TDM, RTAS and AudioSuite.

Two mastering limiter plug-ins

ML1 is a broadband stereo mastering limiter with a brick wall design and knee control

ML4 is a multi-band mastering limiter

Each band's gate, expander and compressor can be configured separately, or linked together

Multiple real-time metering options in each band allow quick visualization of all signal dynamics

The ML4 crossover page shows the overall frequency response in real-time of the input, output, or total dynamics effect, on top of the graphically adjustable crossover frequencies
