Free vocal tuner

Sing a steady note and see where your pitch lands. Real-time note detection and a simple pitch trail turn listening into focused practice.

Use the vocal tuner as a practice mirror, not a score. Match a reference tone, sustain a comfortable note and watch how it moves around center. Natural vibrato will move the display; a perfectly flat line is not the goal.

See how a held note settles

Enable your microphone on this free vocal tuner and sing a comfortable held note while watching the note name, cents reading, and recent pitch trace. The feedback helps you notice whether you tend to drift sharp or flat as a phrase continues. For instruments, use the free tuner instead. Keep listening to your voice as well as watching the display.

Listen first, then sing it back

Choose a reference note, listen carefully, and sing it back in a comfortable part of your range. Reference playback pauses pitch detection, so let the tone finish or stop it before checking your own voice. When a phrase is steady, take it into a music video template. This is feedback for ear training, not automatic pitch correction.

Use the vocal tuner

Three steps. Straight to the music.

  1. Get comfortable

    Use a quiet room and a comfortable singing volume. Allow microphone access only when you are ready to practice.

  2. Hear a reference

    Play a reference tone, listen, then sing it back. The detector pauses during the reference to avoid listening to its own speaker output.

  3. Watch your pitch settle

    Follow the note, cents and recent pitch trail. Center the note gently and take breaks rather than forcing your voice.

A few things worth knowing

No. This is a live pitch monitor for practice. It shows the note you sing and your distance from it; it does not apply Auto-Tune, change your voice or export processed audio.
