EARLY PRACTICE · 18+
Your song. Your practice.
Load an audio file, put on headphones, and sing along. Repeat the part you want to work on while watching your voice’s pitch.
Stays on this device · MP3, M4A, WAV and other browser-supported audio · up to 100 MB. Use audio you have permission to use.
No file? Play your music separately through headphones, then start the microphone here. Other apps may interrupt microphone access; keep this page visible.
Use headphones. A recording playing through speakers can be mistaken for your voice. The app does not remove the original singer.
Estimated microphone pitch
—Waiting for a clear pitch
This mode shows the pitch it hears. It cannot tell whether you sang the song correctly without a target melody. The detector can miss singing or return a wrong pitch; gaps are not a judgment of your voice.
Microphone off
Your file, its name, and microphone audio stay on this device. No recording, upload, or automatic practice tracking. Stop, switch modes, or hide the page to turn off the microphone.

YOUR NEXT SONG
Which song do you want to sing?
Pick a YouTube video or Spotify track and tell us the part that gets you stuck. Your requests will help us choose what to build next.
Song requests are research, not automatic song analysis. You can sing with a local audio file today. Matching its melody automatically is not available yet.
