Bass Management + Sub Enhancement · macOS AU / VST3

Own the low end.

A Linkwitz-Riley crossover splits your signal, sums the bass to mono for club systems, and hands you surgical control below the divider — harmonics, saturation, envelope, sidechain, and stereo width up top. Everything above stays untouched.

The signature

See your bass health in real time.

The Freezer display tracks ice integrity, phase correlation, tuning, and a live sub oscilloscope — so you know exactly what's happening below the crossover. RIG CHECK folds to mono to confirm your low end survives a club system before you send it.

Under the hood

Everything the low band needs, in one split.

Mono-safe bass management, sub enhancement, and forensic monitoring — with the top band left clean unless you touch it.

Crossover + bass shaping

  • Linkwitz-Riley crossover at 24 or 48 dB/oct with a draggable divider
  • Mono bass summing below the crossover for club-safe playback
  • Warm, Punch and Grind saturation modes for the low band
  • Envelope shaper with independent attack and sustain

Sub enhancement

  • Octave-down sine harmonics from autocorrelation pitch detection
  • Bass Key locks sub harmonics to a musical note
  • Sidechain pulse ducks the bass on internal transients
  • SUB DROP triggers an instant sub-bass drop

Top band

  • Mid/Side width control above the crossover
  • Bitcrush and dropout texture on the side channel
  • Low band stays mono while the top keeps its stereo image

Monitoring + workflow

  • Freezer display with Ice Score, phase correlation and sub scope
  • Tuning indicator with detected note and sharp/flat deviation
  • RIG CHECK mono fold and THAW dry A/B toggle
  • A/B two full states, randomize, and share settings via Frequency Seed
