Meta helps you manage your ever-growing digital music collection. Use it to easily edit information such as a song's artist, title, album, album cover, etc. It supports editing of most audio formats such as MP3, MP4, M4A, FLAC, Ogg, OGA, SPX, WAV, AIFF, and a variety of metadata formats including ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, Vorbis comments, and APE tags.

Features:

• A polished, intuitive user interface that adopts OS X's standards
• Write metadata to multiple files at once (Batch Tag Editing)
• Remove all metadata from files (Strip Tags)
• Change typecase (capitalise, upper/lowercase, titlecase), strip underscores
• Rename files based on their metadata or instead, convert filenames to metadata
• Find and Replace characters, words, or strings in metadata, with support for regular expressions (patterns)
• Add selected tracks to iTunes, or refresh their metadata using a simple keyboard shortcut
• Automatically generate track numbers
• Benefit from built in file management operations (Move, Delete, Reveal in Finder)
• Interface is compatible with Retina displays

Album covers can easily be set or exported via drag-and-drop, and it is possible to configure Meta so that it scales, crops, and compresses images each time a new image is set, so as to keep your audio files' size to a minimum.
