What this tool is good for
This tool converts audio formats such as MP3, WAV, OGG, AAC, and WMA into .mid files for AI-assisted music transcription. MIDI stores note events rather than raw waveforms, so the exported files are usually very small.
The transcription model runs inside the browser, so your audio file is processed locally instead of being uploaded to a remote server.
Supported formats and output
- Input: common audio files such as MP3, WAV, OGG, AAC, and WMA.
- Output: a standard MIDI file that you can download as .mid.
- Processing time depends mainly on local device performance and the size of the input audio.
How to use it
- Click to select an audio file or drag it into the upload area.
- The conversion starts automatically after the file is loaded.
- Download the generated .mid file when processing finishes.
Conversion notes
- The page may be temporarily non-interactive while the model is working; that is normal.
- A full song can take one to two minutes depending on your device.
- The current implementation significantly reduces UI freezing compared with earlier versions, so long conversions are more stable than before.
