I produced several songs with voice and piano or guitar chords. I am looking for software, ideally open source in Python, that takes a WAV or MP3 file and produces a MIDI file, which I can then convert to sheet music. I am OK with 70% accuracy, as I can produce the voice and instrument tracks independently and clean up afterwards. My question is similar to Looking for a Transcription Program but for macOS and ideally open-source. I believe the recent progress in neural networks would have made significant impact in this field.
What automatic music transcription software do you recommend?
