About MIDIFLOW
Converts audio recordings into editable MIDI data including note timing, velocity, and pitch bends. The tool processes files entirely on the user’s device without sending audio to external servers. Supported formats include MP3, WAV, M4A, FLAC, and OGG. It uses Spotify’s Basic Pitch model for transcription, which estimates note onsets, pitches, and contours locally in the browser. The output is a standard .mid file compatible with digital audio workstations like Ableton Live, Logic Pro, and FL Studio. Sensitivity controls allow adjustment to balance missed quiet notes against false positives. The tool is designed for musicians and producers who need to extract MIDI data from audio for editing or arrangement purposes.

Frequently asked questions about MIDIFLOW
Does MIDIFLOW upload my audio anywhere?
No. The recording is decoded and transcribed entirely within the user's browser. MIDIFLOW only downloads the transcription model and does not send the audio file to any external servers.
Which audio formats can I convert to MIDI?
The tool accepts MP3, WAV, M4A, FLAC, and OGG files. Browser codec support may vary, so standard formats like MP3 or WAV are recommended for reliability.
Can audio with chords become MIDI?
Yes, the tool supports polyphonic transcription. Clean piano or guitar chords can work, but dense arrangements are less reliable than a single melodic line.
Why did the converter add notes I cannot hear?
Strong harmonics, reverb tails, or overlapping instruments can be misinterpreted as separate pitches by the model. Adjusting sensitivity or using a cleaner solo track can help.
What information is included in the MIDI download?
The MIDI file includes detected note pitches, start times, durations, velocity, and pitch bends where they can be safely written without affecting overlapping notes.
Can I use MIDIFLOW without creating an account?
Yes. There is no requirement to sign up, pay, or provide personal information. Processing is done locally on the user's device without watermarks.
