Open the tuner, allow microphone access, and play or sing one steady note. Vocuno shows the nearest target note, frequency, and cents sharp or flat in real time.
Switch between chromatic tuning, standard guitar, drop D, bass, ukulele, and violin.
See exactly how sharp or flat the note is instead of guessing from a blinking light.
Audio stays in the browser. The tuner does not upload recordings or use a backend service.
Tune instruments or vocals with real-time note and cents detection.

Workflow
Pick chromatic mode or the instrument preset that matches your strings.
Grant browser microphone permission and play one clean note at a time.
Adjust until the cents needle sits near zero and the note display turns stable.
The tuner listens to the microphone through the Web Audio API, estimates the fundamental frequency of the incoming sound, and maps that frequency to the nearest musical note. For instrument presets, Vocuno compares the detected pitch to the target strings instead of only using chromatic notes.
Use a quiet room, play one string or sing one note at a time, and keep the note steady for a moment. Like any tuner, it is designed for monophonic pitch. Full chords, loud background noise, and heavy effects can make pitch detection less stable.
Yes. The tuner runs in your browser and does not require signup, credits, or a download.
No. Pitch detection happens locally with the Web Audio API. The audio stream is not sent to Vocuno servers.
Yes. Use chromatic mode to see the closest sung note, frequency, and cents offset.
Most jumping comes from noisy rooms, chords, short notes, or very quiet input. Play one sustained note and move closer to the microphone.
Keep creative AI tools, pitch and tempo checks, stems, voice conversion, and the Studio editor in one production workflow.
