OTTX: Multiband Upward & Downward Compressor by Rave Generation

Each of the three bands has its own upward compression, which brings up quieter parts, and downward compression, which pushes down louder parts. Both are scalable from 0 to 200 percent, so you can move from subtle control to heavy squashing.

Threshold offset, downward ratio and makeup gain (-40 to +6 dB) are set per band, so the dynamics of each frequency range can be shaped independently. Global attack and release scaling lets you adjust timing for all bands at once.

The crossover frequencies are adjustable: the Low/Mid split ranges from 28 to 148 Hz and the Mid/High split from 2000 to 3000 Hz. Per-band Inflator waveshaping adds harmonic density without traditional clipping, and the developer positions it as an alternative to standard saturation.

The wet/dry mix (0 to 100 percent) supports parallel compression, keeping transients while adding density. A sidechain high-pass filter (0 to 200 Hz) keeps sub-bass from causing pumping, and Smooth Mode switches to RMS detection with soft-knee compression for more transparent results. Smart Clip 0dB holds the output at or below digital full scale.
