MIDIFLOW
MIDIFLOW converts audio recordings into editable MIDI files for further work in music software.
What MIDIFLOW is
MIDIFLOW converts audio recordings into editable MIDI files for further work in music software. It accepts MP3, WAV, M4A, FLAC, and OGG files, then uses Spotify’s open-source Basic Pitch model in the browser to transcribe them on your device rather than upload them to an audio-processing server. You can compare the recording with a synthesized MIDI preview and adjust the note threshold to omit quieter notes. Downloads can include note pitches, start times, durations, velocity, and eligible pitch-bend events. The site provides import instructions for Ableton Live, Logic Pro, and FL Studio. MIDIFLOW is free forever at no cost, with no signup, watermark, payment, or credit system. Its maker presents the result as a starting point for editing, noting that dense arrangements are less reliable than a single melodic line. Very large files may exceed available device memory, particularly on phones. The policy says the service currently has no advertising, behavioral tracking, or first-party analytics.
