Real-time vocal pitch detector and singing game — practice singing, train your ear, detect notes and frequencies, all in the browser. Free, private, works offline.
A fun, browser-based singing practice app. Use your microphone to see what note you're singing in real time — or play a game where you sing through the musical scale.
Singing Experience is a small web app that listens to your voice through your device's microphone and tells you what musical note you're singing. It's designed for anyone who wants to explore their voice, warm up before singing, or just have fun with music — no musical training required.
Sing or hum into your microphone and instantly see:
- The note you're singing (like C, D, E, etc.)
- How in-tune you are (are you a little sharp or flat?)
- The frequency of your voice in real time
🎙️ Singing & voice practice
Warm up your voice and verify you're landing on target pitches. Use the voice range presets (Soprano, Alto, Tenor, Baritone, Bass, and more) to focus the display on your register. The cents deviation and pitch history chart reveal whether your intonation is solid or drifting over time.
👂 Ear training
Sing or hum an interval, then check whether you matched the pitch you intended. The pitch history chart gives a visual trace of your pitch over time — a flat line close to zero cents means you held the note rock-steady.
🎼 Music education
Demonstrate acoustics live: play a note and show students its frequency in Hz and its name on the musical scale. The visual feedback makes abstract concepts like "sharp" and "flat" immediately concrete.
🎵 Composition & transcription
Hum a melody fragment and read off the notes one by one. Useful for sketching out ideas when you don't have an instrument to hand or can't read sheet music on the fly.
🎸 Instrument tuning
Play a note on any acoustic instrument — guitar, ukulele, violin, piano, flute, recorder — and the app instantly shows the note name and how many cents off you are. A visual sharp/flat bar makes it easy to nudge the string or breath pressure until you land exactly on pitch.
A step-by-step singing game that walks you through the classic musical scale — DO, RE, MI, FA, SO, LA, TI, DO.
- The app shows you which note to sing next

Everything happens on your device. This is a static app — there is no server and no backend.
- Your microphone audio is never recorded
- Your voice data is never sent anywhere
- No data leaves your browser — everything runs 100% locally on your device
- The app simply analyzes your voice in real time and shows you the result on screen
You will be asked to allow microphone access when you start a program. This is a standard browser permission — the app needs it to hear your voice. You can revoke this permission at any time in your browser settings.

The app is deployed to GitHub Pages and updates automatically on every push to main.
To run the app on your own computer, you need Node.js installed (version 24 or later is recommended).
-
Download or clone the project
git clone https://github.com/kunukn/singing-experience.git cd singing-experience -
Install dependencies
npm install
-
Start the app
npm run dev
-
Open your browser and go to the address shown in the terminal (usually
http://localhost:5555)
That's it! The app runs entirely in your browser.
iPhones and iPads have a silent mode switch. When silent mode is on, the browser cannot play any audio — even if the in-app volume is fine.
Fix:
- Older models — flip the physical silent switch off (so no orange is visible).
- Newer iPhones and iPads — open Control Center and tap the Silent Mode button to turn it off.
- Also check that Do Not Disturb is off (Control Center → Focus → Do Not Disturb), as it can suppress audio too.
- Make sure your device volume is turned up — use the physical volume buttons.
- Check that Do Not Disturb mode is off (it can suppress audio on some devices).
- If you're connected to Bluetooth headphones or a speaker, audio may be routed there instead of the device speaker.
If audio seems to play but you can't hear it, your device may be routing sound to a Bluetooth device, HDMI display, or AirPlay receiver. Disconnect external audio devices or switch the output in your device's audio settings.
If you accidentally blocked microphone access, the browser remembers your choice and won't ask again. The app needs microphone permission to hear your voice — without it, nothing will work.
