How to convert .mp3 audio files to .xml format.
Converting MP3 Audio Files directly to MusicXML Files (.mp3 to .xml conversion) should be possible. It relates to users attempting to transform MP3 audio into MusicXML files, which in most cases use the MXL suffix.
Use a music composition and notation software or (online) conversion tool, such as MuseScore or Harmony Assistant, which should allow users to import MP3 audio files in order to generate XML files.
