HarmonEQ is a harmonic exciter EQ that adds musical harmonics and saturation to your audio instead of simply boosting or cutting frequencies. Featuring three parallel harmonic bands with six selectable saturation types per band, dual-channel Stereo/Mid-Side processing, per-band dynamics shaping, and up to 4× oversampling, it creates perceived loudness and presence without significant peak level increase. A modern harmonic tool for mixing, mastering, and sound design.
LO 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.
Six Per-Band Saturation Types
MAIN (signature smooth inflator curve), TUBE (valve-style even harmonics), WARM (darker softer tube), SOLID (transistor-style odd harmonics), TAPE (magnetic compression feel), and CLEAN (pure EQ, no coloration). Mix and match across bands for endless tonal combinations.
Dual-Channel Stereo/Mid-Side Processing
Process 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 Dynamics
Expand, 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 Quality
Normal (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 Mode
Subtracts the clean EQ boost component, leaving only the added harmonic saturation. Creates a subtle harmonic enhancer effect without changing the overall tonal balance.
Automatic Scoop
Reduces low-mid muddiness proportional to your boost settings. At 0% disabled, 50% default standard depth, 100% double depth—keeps mixes clean when driving bands hard.
Clip 0dB Protection
Soft-clipping followed by hard-limiting at 0dB prevents digital overs when driving input or boosting bands aggressively. Essential for hot mixes and mastering chains.
Channel Controls
Input (dB) – Input gain before processing (−20 to +20 dB). Higher values drive the saturation harder for more harmonic content.
Output (dB) – Output gain after processing (−20 to +20 dB). Use to compensate for level changes.
In/Out – Channel bypass switch. When Off, the channel passes signal unprocessed.
LO Freq (Hz) – Low shelf frequency (20–420 Hz). Default: 100 Hz. Sets where low-frequency saturation begins.
LO Level (dB) – Low band harmonic intensity (−10 to +10 dB). Positive values add warm bass harmonics, negative values reduce low-end content.
LO In – Enables/disables the LO band processing.
MID Freq (Hz) – Mid peak center frequency (200–6200 Hz). Default: 1500 Hz. Wide Q provides musical presence adjustment.
MID Level (dB) – Mid band harmonic intensity (−10 to +10 dB). Generates progressively rising harmonics for exciter-style presence.
MID In – Enables/disables the MID band processing.
HI Freq (kHz) – High shelf frequency (5–25 kHz). Default: 12 kHz. Controls the air and brilliance region.
HI Level (dB) – High band harmonic intensity (−10 to +10 dB). Adds smooth saturation for air and shimmer without harshness.
HI In – Enables/disables the HI band processing.
Saturation Type (per band) – Selects harmonic character: MAIN, TUBE, WARM, SOLID, TAPE, or CLEAN.
Lo Cut (Hz) – High-pass filter frequency (18–180 Hz). Progressive slope removes sub-bass content.
Lo Cut In – Enables/disables the low cut filter.
Hi Cut (kHz) – Low-pass filter frequency (8–40 kHz). Progressive slope removes high frequencies.
Hi Cut In – Enables/disables the high cut filter.
Expand (%) – Widens dynamic range (0–100%). Louder parts get gently boosted while quiet parts stay untouched.
Compress (%) – Tightens dynamic range (0–100%). Gently reduces peaks above −12 dB threshold for smooth, transparent leveling.
Transient (%) – Reshapes attack character (−100 to +100%). Positive enhances punch and snap, negative softens attacks.
Dyn Lo / Dyn Mid / Dyn Hi – Per-band enable toggles for selective dynamics routing.
Global Controls
Mode (Stereo / M-S) – Selects Stereo (linked L/R) or Mid-Side (independent mid and side) processing.
Mix (%) – Wet/dry blend (0–100%). Phase-aligned delay compensation keeps the dry signal in phase at all settings.
Quality (Normal / Medium / Best) – Oversampling factor: 1×, 2×, or 4×. Higher quality produces cleaner harmonics at increased CPU cost.
Scoop (%) – Automatic low-mid scoop amount (0–100%). Reduces muddiness proportional to band boost levels.
Clip 0dB (On/Off) – Enables soft-clipping followed by hard-limiting at 0dB to prevent digital overs.
De-Emphasis (On/Off) – Isolates only the added harmonic content for subtle enhancement without tonal shift.
x2 (On/Off) – Doubles internal band intensity for more aggressive harmonic content.
