Three simple steps
How to convert audio to MIDI
- 01
Choose an audio file or isolated stem from your device. Your audio stays in the browser and is not uploaded to ToolYogi.
- 02
Start conversion. The browser decodes the audio and uses an AI transcription model to detect note pitch, timing and dynamics.
- 03
Review the detected note count and download the resulting standard MIDI file for use in FL Studio, Ableton, Logic, Cubase or another DAW.
What kind of audio works best?
Audio-to-MIDI transcription works best when one pitched instrument or voice is prominent, such as a vocal melody, bassline, piano, guitar or isolated stem. A full mastered song with many instruments can produce extra or incorrect notes because several pitches overlap.
What does the MIDI contain?
The generated MIDI represents detected musical notes, their timing, duration and velocity-like intensity. It does not contain the original audio sound. When you import it into a DAW, choose any virtual instrument or synthesizer to play those notes.
Does ToolYogi upload my audio?
No. Audio decoding, note transcription and MIDI preparation run locally in your browser. ToolYogi does not create an upload endpoint, cloud history or server-side copy of the selected audio for this tool.
Why can the MIDI differ from the recording?
Automatic transcription is an estimate. Reverb, bends, chords, overlapping instruments, background noise and very fast notes can affect detection. Use the MIDI as an editable starting point and correct individual notes in your DAW when needed.

Frequently asked questions
Is the Audio to MIDI Converter free?
Yes. The current ToolYogi converter runs in your browser without an account.
Which audio formats can I use?
The tool accepts common browser-decodable formats including MP3, WAV, M4A, AAC, OGG, FLAC and WebM. Actual codec support depends on your browser.
Does my audio leave my device?
No. The selected audio is decoded and transcribed locally in your browser. Only the transcription model and application code are downloaded from the web.
Can I convert a complete song to MIDI?
You can try, but results are usually better with an isolated instrument or stem. For a full song, separate the track into stems first and convert the pitched stem you need.
Can it convert vocals to MIDI?
Yes. A relatively clean solo vocal melody can be transcribed into MIDI notes. Expressive slides and ornamentation may still need editing afterward.
Can it convert drums to MIDI?
This tool is intended primarily for pitched notes. Dedicated drum transcription that maps kick, snare and hi-hat to drum MIDI notes is better handled by a separate drum-to-MIDI tool.
Powered by open-source transcription
Audio-to-MIDI transcription uses Spotify Basic Pitch through a browser-first integration. Basic Pitch is Apache-2.0 licensed and is designed for polyphonic pitch transcription, with best results when one instrument is analyzed at a time.
