Audio::BunnyMusicFile is a Perl module for working with a music collection in a high-level way. It supports the decoding and encoding of music files, tag editing, and naming based on file properties. The behaviour of the module is controlled through a flexible configuration file, allowing consistant behaviour between user applications.
musutil includes several utilities for working with a music collection. The principle one is musview, which generates a number of "Views". Each View, analogous to a database view, is an alternative presenation of the original files. The View can selectively include only some files (based on their properties) or have files processed into into a different format, with audio filters applied, adjusted tag data, or a different filename.
