Is there a way to convert .abc files to .mp3 format?
Converting ABC Music Notations directly to MP3 Audio Files (.abc to .mp3 conversion) is possible and should be quite straightforward.
Use one of several music composition and notation programs, such as MuseScore or Harmony Assistant, which should allow users to import ABC notations and export them in MP3 format.
