• 🎤 Vibrato Rate Analyzer

    Sing a sustained note into your computer microphone and measure your vocal vibrato rate, pitch, vibrato width, and consistency in real time.

    Click "Start Singing" and allow microphone access. Then sustain one comfortable note for several seconds.

    🎵 What is this measuring?

    The analyzer tracks changes in the fundamental frequency of your voice. When you sustain a note with vibrato, your pitch repeatedly moves above and below a central pitch.

    The estimated vibrato rate tells you how many of those oscillations occur each second. For example, 6 Hz means approximately six complete pitch oscillations per second.

    Vibrato width estimates how far your pitch moves from the center pitch and is displayed in cents.

    For the best result, sustain one comfortable vowel for at least 3–5 seconds. Avoid intentionally speeding up or slowing down your vibrato.
    ⚠️ Important:

    This is an educational microphone-based estimator, not a professional pitch-analysis system. Background noise, room acoustics, microphone quality, breath noise, harmonics, vocal onset, and changes in pitch can affect the result.

    A singer may also have natural changes in vibrato rate throughout a note. Don't treat one measurement as a "correct" or "incorrect" vibrato rate.
