§ 01   Modules

Three modules.
One app.

Each module targets a distinct aspect of classical vocal technique. They share a single calibration and a common session architecture.

01 In testing

Squillo Meter

Measures singer's formant resonance — the high-frequency ring (~2.5–3.5 kHz) that gives operatic voices carrying power. Real-time SFB ratio display, calibrated to your voice, scored against your own baseline.

02 Planned

Pitch Tracer

Pitch accuracy tracking across sessions. Visualise intonation tendencies, compare across repertoire, identify patterns over time. Designed for the singer who already has strong ears and wants objective data.

03 Planned

Target Tuner

Guided training against a specific acoustic target — set the parameter, work toward it in real time. Builds on the calibration and resonance analysis from Squillo Meter with structured practice sessions.
