ARITA
Extraordinary audio player for FreeBSD & GNU/Linux
Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end.
