MPC Spectral Compressor: Multiband Dynamics Plugin by Harrison Consoles

The plugin divides its 18 compressor bands across a selectable frequency range, from Full Range (16 Hz to 20 kHz) to narrower areas such as Low, Mid or High. Choosing a narrower range concentrates all 18 bands on that region for more precise control.

Six Depth sliders set the maximum gain reduction for groups of three bands each. Depth runs from -24 to 0 dB, and setting a slider to 0 dB stops attenuation in its range. The Threshold, which can be set from -60 to 0 dB, determines where compression starts, while Knee (1 to 30) controls whether it engages abruptly or gradually. A Gain Reduction graph shows the applied reduction across the spectrum, and Output Trim adjusts the output from -10 to +10 dB.

The developer describes the plugin as usable as a de-esser for taming harsh frequencies, as a flexible drum bus processor, and as a subtle enhancer for vocals and instruments. Because each band can be set independently, it can target one problem area, such as a sibilant region, without affecting the rest of the spectrum.

The global controls allow overall tonal adjustments to a mix, such as smoothing harsh highs or boosting low end. The developer states it is suitable across genres, though the controls suit users who want precise, frequency-specific dynamics processing.
