This estimator collapses every voice into one of six broad buckets from F0 alone. The full Suede Sing iOS app classifies across the complete Fach spectrum using a per-singer logistic-regression model fit to your calibration samples, with acoustic markers per fach — tessitura range in semitones, expected H1−H2 distribution per register, spectral tilt baseline, F1/F2/F3 formant signature, singer’s formant cluster intensity, characteristic passaggio MIDI:

• Soprano family — F0 working range C4–C6+, lyric / spinto / dramatic / coloratura / soubrette. F1 baseline 700–900 Hz, characteristic high singer’s formant cluster, passaggio typically C5–E5 depending on subtype.
• Mezzo-soprano family — F0 working range A3–A5, lyric / dramatic / coloratura. Distinctive F2/F3 cluster at 2.4–2.8 kHz, passaggio typically A4–C5.
• Contralto / countertenor — cross-fach M1/M2 inversion patterns. Sopranist, mezzo, alto subtypes. Reads like a soprano above the break with a chest baseline below.
• Tenor family — F0 working range C3–C5+, lyric / spinto / dramatic / Heldentenor. Singer’s formant ~2.8 kHz, distinctive H1−H2 chest signature, passaggio typically E4–G4.
• Baritone family — F0 working range G2–G4, lyric / Verdi / dramatic / bass-baritone. F1 baseline 500–650 Hz, passaggio typically B3–D4.
• Bass family — F0 working range E2–E4, basso cantante / basso profondo. Low spectral centroid, characteristic F2 plateau, passaggio typically G3–A3.

Plus non-binary tessitura mapping and CCM-specific belt categorization that doesn’t fit cleanly inside the operatic Fach taxonomy.

In short: this tab gives you F0 min and F0 max. The iOS app gives you the full feature vector, longitudinal trajectories, register classification, compensation diagnostics, and the targeted drill set.
