MP3s are among the most accessible audio file types across the Internet, and are commonly used with car CD players, discs, file sharing programs and various media players. Another, less common file type is the RSN or Reason Project File format, which is a type of audio production that is used by synthesizer and music creating programs. You can convert your RSNs to MP3 in just seconds with the right online tools.
