HarmoniQ is an automatic EQ that analyzes audio, detects the fundamental and removes inharmonic frequencies with up to 50 precision filters.

An Effect Amount knob scales the cuts, up to -18 dB per filter, and a Delta mode lets you hear what is removed. It costs €34.99 (about $39.73).

Best for: Vocals, Acoustic Instruments, Guitars, Mix Bus. Genres: all genres.

Keywords: vocals, AUv3/iOS, dynamic, A/B compare, acoustic guitar, bus processing, corrective, electric guitar, full mix, mix bus, mixing, resizable UI.

What it does

HarmoniQ is HoRNet's "automatic equalizer designed to effortlessly clean up your sound." It uses FFT analysis to find the fundamental of the source and cuts frequencies that don't belong to its harmonic series.

Analysis: real-time detection of the fundamental and of inharmonic frequencies.
Filters: up to 50 filters at once; the Effect Amount control scales each cut from -9 dB to -18 dB.
Learn modes: Auto stops detection once the filters have been stable for 10 seconds; On Stop ends learning when DAW playback stops.
Frequency range: Lower Limit and Upper Limit controls keep the processing to the band you choose.
Delta: audition only what is being removed, plus bypass for A/B comparison.
Workflow: a Reset button to restart detection, preset load and save, and a resizable UI.

The current version is 1.1.5. HoRNet offers a 15-day money-back guarantee, and the demo silences periodically and does not save settings or respond to automation.

When to use it

HarmoniQ is the pick for cleaning up a single tonal source by what doesn't fit its harmonics, rather than by what is loud or harsh. Compared with soothe3, it does not chase resonances dynamically across a dense mix; it learns a set of filters from the note's harmonic series and then holds them. Unlike TDR Arbiter or OD Finesse, it needs almost no setup beyond the amount and frequency limits. It is also far cheaper than soothe3, though users warn it can leave a source sounding sterile if pushed.

Best for: muddy vocals, boxy acoustic guitars, hum on guitar tracks and cluttered tonal parts.
Genres: any style, particularly acoustic and vocal-led music.
Look elsewhere if: you need to tame harsh resonances across busy mixes (soothe3) or want to set the key yourself; one forum user found Scaler EQ more configurable for that.
Tip: use the Delta function to hear what is being cut, and lower the Effect Amount if the result starts to sound thin.

What producers say

Feedback from iOS users is mixed: useful for problem tracks, but some find the result sterile.

Loopy Pro forum (iOS version) users found it useful on guitars, including for "reducing some unwanted hum", and one used it in mastering alongside compression and limiting.
Comparison: one user's test against Scaler EQ found HarmoniQ sometimes gave better results on vocal timbre, though Scaler EQ is more configurable.
Criticisms: one user said it "sounds super sterile", another warned of taking out too much harmonic content, and some found the CPU use high on iOS.
