60% Overtone Dominance Discrepancy & fโ‚€ Extractor

CORPUS AUDIT: 213/354 FLAGGED
Commercial Sample Platform Tagging
Naive Loudest FFT Peak Finder (False C4)

Detects peak amplitude at 258.4 Hz. Tags sample as Key "C", creating a dissonant clash when used in F major.

THIRI Acoustic Engine
Sub-Harmonic Fundamental Extractor (True F2)

Isolates true acoustic root at 86.1 Hz. Correctly classifies 258.4 Hz as the 3rd partial (perfect 5th overtone).

HARMONIC SERIES LADDER: Crystal Singing Bowl in F (Fundamental fโ‚€ = 86.1 Hz) TAGGED KEY: C4 (DISCREPANCY DETECTED)
Sample Selection: Acoustic sources prone to overtone dominance
Sub-Harmonic Search Depth: Depth of sub-harmonic root candidate evaluation
Harmonic Tolerance Window: ±25 Cents Acoustic inharmonicity tolerance band

The Producer's "Bassline Trainwreck" Test

Everyday Analogy: Imagine a wine bottle labeled "Sweet Vanilla" when it is actually "Spicy Chili" because the label scanner only read the brightest color on the cap. When a musician trusts the AI's wrong key label (C instead of F) and plays a bassline underneath, the song clashes terribly. Click below to hear both basslines against the singing bowl!
