Find my octave, then adapt a clip
Measure your comfortable pitch range with the microphone. Upload a short reference (song line or teacher take), see the suggested transpose, and preview it in your octave.
1. Detect your range
Allow microphone access. Hum or sing steadily for 10–20 seconds across low → high notes you can reach comfortably.

2. Adapt a reference clip to your octave
Upload a short audio snippet. We estimate its pitch center and shift playback toward your center (playback-rate transpose — good for practice previews).

Why octave matching for languages?
Shadowing a model that sits far outside your range is exhausting. Matching octave keeps focus on intonation shape — the language skill — not strain.
