Harmonic resonances, in writing.
How the grid places related bells, when a stock EQ is still the right tool, and how to plant a root on the graph.
What is a harmonic-grid EQ — and why a parametric EQ fights you
A parametric EQ treats every frequency as an isolated decision. A harmonic-grid EQ treats a note as a family of related overtones. That difference is the whole product.
GuideWhy boosting 80 Hz made the bass boomier — not bigger
The search is usually 'how to EQ bass so it cuts through.' The mistake is almost always boosting the fundamental when the mix needed the harmonics.
ReferenceFundamentals vs overtones: the mixing distinction that actually pays rent
Pitch lives in the family. Weight lives in the root. Confusing the two is how bright vocals get harsh and fat kicks get small.
ReferenceOctaves, odd harmonics, and why RootEQ uses primes instead of a 12-note scale
Prime 2 is octaves. Prime 3 and 5 walk into the odd-harmonic world where guitars get boxy and square waves get their teeth. It is not a tuner.
GuideHow to add presence without turning the vocal into a whistle
The Google query is 'vocal presence EQ 3k 5k.' The useful version is: which partial of this voice is doing the work, and which one is the blade.
GuideWhen a standard parametric EQ is the better tool than RootEQ
RootEQ is not a Pro-Q replacement. Here is the honest split, so you do not buy the wrong object — or blame the right one.
ReferenceZero-latency peaking filters: what RootEQ does to phase, and what it does not
Every analog-style bell rotates phase. Linear-phase EQs delay the whole signal to avoid that. RootEQ picks the first camp on purpose.
GuideHow to place a root by ear (using the analyzer without worshipping it)
Double-click the graph. That is the whole onboarding. The analyzer is a hint, not a verdict — especially on notes that move.
GuideTreat a resonance as a family, not a spike — the case for branching
Boxy guitars, ringing toms, and 'honky' synths are often a partial plus its relatives. Cutting one spike leaves the cousins.
