ML4000 consists of two powerful plugins designed for mastering and dynamic control. The ML1 mastering limiter features a brick wall look-ahead design with multiple stages of limiting, ensuring precise peak detection and control. Its unique Knee and Mode controls allow it to adapt to various audio materials, delivering responses that range from clean and transparent to more aggressive, tailored to suit different mastering needs.

The ML4 is a sophisticated multi-band dynamics processor combining a 4-band Gate, Expander, and Compressor, all driven by the same limiter algorithm found in the ML1. Each band can be independently configured or linked for cohesive processing. Steep 24 dB/Oct crossover filters effectively reduce signal bleed between bands, while multiple real-time metering options provide clear visualization of dynamic changes in each frequency band. This detailed control enables precise shaping of the audio signal.

Additional features include a real-time crossover frequency display for monitoring the input, output, and overall dynamic effect, simplifying adjustment and fine-tuning. Output ceiling control, large meters, and level readouts facilitate quick and accurate output management. With analog saturation modeling, double precision processing, and low latency operation, ML4000 delivers high-quality performance in both mono and stereo formats, making it a reliable tool for mastering and dynamic processing tasks.
