1. Is this Audio to MIDI converter free?

Yes. You can convert audio to MIDI for free directly in your browser.

2. Do I need to upload my files to a server?

No. Transcription runs in your browser, so your file stays on your device.

3. Which input formats are supported?

You can use common audio formats such as MP3, WAV, OGG and FLAC as input, and the tool outputs a .mid file.

4. How accurate is the transcription?

It works best on clear, monophonic melodies. Dense mixes or heavy polyphony may reduce accuracy.

5. What can I do with the .mid file?

Open the MIDI file in any DAW to change instruments, edit notes, or build a full arrangement.

6. Is there a file size or length limit?

There is no fixed product limit, but longer or larger files may take more time depending on your device.

7. Can I use this on mobile?

Yes. The page works on both desktop and mobile browsers.

8. What if the conversion fails or finds no notes?

Try a clearer, more melodic track, or another file. Corrupted audio may fail to decode.
