This vocal pitch analyzer plots your fundamental frequency in real time from the mic — see intonation, vibrato width, and stability as you sing. No app install: open the page, allow the mic, and use it for warmups, phrase work, or passaggio checks.

See exactly where your voice goes flat or sharp

The trace shows pitch drift through a line or phrase so you can spot sharp entrances, flat releases, and unstable vowels — adjust technique and sing the same line again to compare.

How singers use the pitch graph for intonation practice

Sing scales, arpeggios, or song fragments while watching the graph: aim for a smooth line on sustained notes and consistent peaks on repeated patterns.

Warm up your voice and track pitch stability over time

Use short sessions before rehearsals or gigs: lip trills, sirens, and long tones — the display helps you notice when your warmup has “settled” versus when you are still straining.

Works for all voice types — soprano, alto, tenor, bass

The detector follows the fundamental of whatever you sing; work in the part of your range you are training that day, from chest to head voice and mix.

How to Use Pitch Visualization

The graph shows estimated fundamental frequency over time. The vertical axis is logarithmic so equal musical distances (semitones) look evenly spaced whether you sing low or high.

Before you see a trace

Turn on the microphone from the control strip and allow access. If the readout says the sound is too quiet, open Settings (gear) and raise Microphone Sensitivity, or sing/play closer to the mic.
Pitch points only appear when the detector finds a stable tone above the sensitivity threshold; noisy or very soft passages may show gaps.

Recording vs playback

While recording, new points are added along the timeline in real time.
When you stop, the curve stays so you can review the take. Starting a new recording clears the previous trace for a new session (depending on app reset behavior).
During playback, the chart can follow the playhead and show the note name and frequency at the current time.

Chart interaction

Auto-follow (default): the time window scrolls so recent audio stays in view.
Click and drag on the plot to pan along time or frequency; this usually pauses auto-follow until you re-enable it.
Double-click the chart to reset zoom and re-enable auto-follow (behavior shown in on-canvas hints).
If you dragged the time axis earlier, use playback reset or a new recording so the window is not stuck off-screen on mobile.

Good use cases

Vocal intonation, interval practice, and seeing vibrato width over time.
Instrument tuning and comparing long tones across registers.
Pair with the Vocal Recorder page for gain, monitoring, file export, and precise scrubbing on the progress bar.

Vocal practice ideas

Spot flat or sharp moments in a phrase while you sing — adjust vowels and support, then repeat.
Observe vibrato width and steadiness on sustained notes.
Compare pitch stability before and after a warmup routine.
Check intonation at the top and bottom of your comfortable range.
