What is this?
Melody Sheet Analyzer is a free, privacy-first web tool that helps musicians, students, and music lovers turn their melodies into readable sheet music.
How to Use
- Click or drag your audio file (.mp3 or .wav, max 100MB) to the upload area above.
- Click "Start Analyzing" to extract the melody notes from your audio. You can preview your audio and see the detected notes in real time.
- Once analysis is complete, click "View Sheet Music" to see your melody as sheet music and download it as SVG.
How it Works
The tool uses the Web Audio API to decode your audio file directly in your browser. It then applies the open-source pitchy library to extract the main melody pitch from your recording. Each detected pitch is converted to a standard note name (e.g., A4, C5) using a logarithmic formula. Finally, the notes are rendered as beautiful sheet music using VexFlow.
