How to record

Take a breath, pick a comfortable pitch, and sustain an open 'ah' for at least 3–5 seconds. Let your natural vibrato engage — don't force a shake. Stay close to the mic in a quiet room.

Why use the Vibrato Analyzer?

Objective vibrato numbers

See your vibrato rate in Hz and depth in cents — the same metrics singers and coaches use — instead of guessing from feel alone.

Consistency and coaching

Get a quality score, a clear band label, and specific tips for slow wobble, fast tremolo, narrow flutter, or a straight tone with no vibrato yet.

Private and free

Frequently Asked Questions

What is vibrato?

Vibrato is a regular, controlled oscillation of pitch on a sustained sung note. Trained classical vibrato often cycles about 5–7 times per second with a moderate depth. It is different from a slow wobble, a nervous bleat, or random pitch shake from weak breath support.

How does the vibrato analyzer work?

You sing and hold a steady note for a few seconds. Our AI listens for pitch oscillation and estimates vibrato rate (Hz), depth (± cents), consistency, and regularity, then returns a score, a band label, and coaching tips.

Is my recording stored or shared?

Your audio is processed securely for analysis and never shared. No account is required to use the tool.

Is it really free?

Yes. The vibrato analyzer is completely free with no signup required. There is a fair-use daily limit to keep the tool responsive for everyone.
