After Me

a patient singing examiner · it sings first, you reply

BEFORE WE BEGIN

Good day. I am your examiner. The procedure is simple: I sing a short phrase; you sing it back whenever you're ready — the notes, and the timing between them. You set the moment, I follow. We start gently and the material grows with you, one musical idea at a time. First, where does your voice live?
Sing in whatever octave suits your voice — octaves are always forgiven.
Headphones recommended (so I don't hear myself and neither do you, twice).
Audio is analysed locally and never leaves your device. The microphone requires a secure context — use localhost or https.
Everything runs in this page: the phrases are generated, the voice is synthesised, and your singing is pitch-tracked and marked locally. Scores measure three things separately: the notes you hit (pitch), the intervals between them (shape), and when you sang them (rhythm). Sibling of Fortissimo, the notepad that knows how hard you typed, and Pen, which draws what you meant, not what your mouse did — all at tools.j11y.io.
