How to use the vocal spectrum analyzer
Start the microphone, hold one comfortable note, and watch pitch, harmonics, formant candidates, warnings, captures, and reference examples.
1. Allow microphone access
The audio is processed in your browser. Raw voice audio is not uploaded or stored on a server.
2. Hold a stable note
Start with a 2-3 second note before judging harmonics or formants. Stable pitch makes the graph easier to read.
What to read first
Read Pitch first, then H1/H3/H5, then F1/F2/F3. Capture useful moments and compare them with synthetic reference examples under the same microphone setup.
Open the analyzer and compare your graph with a reference example.
