How to use Pitch Detector

1

Start listening

Enable microphone access from your browser.

2

Sing or play one note

Hold a single pitch so the detector can lock onto the fundamental.

3

Read the result

Use the note, cents, and frequency readout for tuning, practice, or transcription.

What note am I singing?

The detector converts microphone audio into a waveform, estimates the fundamental pitch, and rounds it to the nearest chromatic note. The cents value shows whether the pitch is above or below that note, which is useful for singers practicing intonation.

Pitch detector vs tuner

A tuner is optimized around a target note or instrument string. A pitch detector is more exploratory: it tells you what note is happening right now and how it changes over time. Vocuno includes both because singers and producers need both workflows.
