The 6 Critical Frequency Bands

Your mix's frequency spectrum is divided into 6 bands. MixDiagnose scores each one — no band should be more than 6-8 dB louder than its neighbors.

20-60 Hz

Felt, not heard. Kick drum body, sub-bass energy.

Target: Controlled

60-250 Hz

Bass, kick punch, guitar warmth. #1 problem zone.

Target: Balanced

250 Hz-2 kHz

Vocals, guitars, snare, piano. The heart of the mix.

Target: Even

2-6 kHz

Presence, attack, harshness zone. Where ears fatigue.

Target: Controlled

6-12 kHz

Cymbals, air, sibilance. Brightness and clarity.

Target: Present
