Harmonic analysis: key, resonances & tonal character
Harmonic analysis reads the musical and tonal content of your track — its key, its resonant peaks, and the harshness that makes a mix tiring. Unveil detects the key with a chromagram (Krumhansl-Schmuckler), finds narrow resonant peaks and sibilant/harsh build-ups, and tells you where the tonal balance is fighting itself.
What you get
- Musical key detection so your corrective and creative moves stay in key.
- Resonance and harshness detection — narrow peaks and 3–8 kHz build-ups that cause ear fatigue.
- How tonal character ties back to the frequency spectrum and genre curve.
- A free readout of resonances and harshness with the frequencies to tame.
Questions
How is the key detected?
A 12-bin chromagram is correlated against the 24 Krumhansl-Kessler major/minor key profiles. It returns a best-fit key, or nothing when the material is too atonal to be confident.
What causes harshness in a mix?
Usually a build-up in the 3–8 kHz presence region or narrow resonant peaks. Unveil flags these so you can de-ess or dip the specific band instead of dulling the whole top end.
