Audio Archive Toolbox is a Windows based suite of tools to compress audio files from 16 or 24 bit wav format, to mp3, aac (m4a), ogg, opus, and flac formats. It can also add ID3V2 tags to compressed audio files, create playlists, create md5 checksum files for all compression formats, and create ffp checksums for FLAC files. AATB can also delete redundant wav files after compression, saving space for archiving.
