Pazera Free MP4 to MP3 Converter is a free program that converts MP4, M4A, M4B (audiobooks), M4R (ringtones) and AAC files to MP3 or WAV format. In addition, the program lets you copy (extract) original audio tracks without any loss of quality.
The program also allows you to split input files based on chapters (often found in M4B files). Metadata by default are copied from the source files, but the user can add their own tags.
