Rave Generation: HarmonEQ

Harmonic EQ
Rave Generation: HarmonEQ
Harmonic exciter EQ where boost and cut are generated by saturation rather than a gain stage. Three parallel bands, five saturation types per band, Stereo/Mid-Side processing. Tone shaping and harmonic content move together.

Features

  • A Different Harmonic Profile Per BandMAIN runs its own harmonic balance in each band rather than one curve everywhere: mostly 2nd harmonic in LO, an even/odd mix in MID, soft and strongly 2nd harmonic in HI.
  • Three Parallel Harmonic BandsLO shelf, MID peak, and HI shelf bands each extract their frequency content, apply harmonic generation, then sum back with the dry signal. The parallel architecture means bands interact musically rather than cascading, preserving natural tonal balance.
  • Five Per-Band Saturation TypesMAIN (a different harmonic profile in each band), TUBE (valve-style, mostly 2nd harmonic), SOLID (transistor-style, mostly 3rd harmonic), TAPE (magnetic saturation, mostly 3rd harmonic), and CLEAN (pure EQ, no coloration). Mix and match across bands.
  • Dual-Channel Stereo / Mid-Side ProcessingProcess linked stereo with a single set of controls, or switch to Mid-Side mode for independent shaping of mono and stereo content. Add warmth to Mid, air to Side. Each channel has its own full set of controls.
  • Per-Band DynamicsExpand, Compress, and Transient shaping applied post-EQ as finishing touches. Selectively route dynamics to LO, MID, or HI frequency bands using the Dyn Lo / Dyn Mid / Dyn Hi toggles for surgical control.
  • Selectable Oversampling QualityNormal (1×) for low CPU, Medium (2×) for cleaner harmonics, Best (4×) for maximum quality. Kaiser-windowed FIR anti-alias filtering ensures pristine saturation at any drive level.
  • De-Emphasis ModeSubtracts the clean EQ boost component, leaving only the added harmonic saturation. Creates a subtle harmonic enhancer effect without changing the overall tonal balance.
  • Automatic ScoopReduces low-mid muddiness proportional to your boost settings. At 0% disabled, 50% default standard depth, 100% double depth, which keeps mixes clean when driving bands hard.
  • Clip 0dB ProtectionSoft-clipping followed by hard-limiting at 0dB prevents digital overs when driving input or boosting bands aggressively. On by default, and only active above -0.18 dBFS.
