Yate

Yate was developed for people who want complete control over their tagging experience. Supports audio in AIFF, DFF, DSF, FLAC, OGG OPUS, OGG VORBIS, M4A, M4B, MP3, MP2, MP4, STEM.MP4 and WAV files. Supports video in M4V and MP4.

Yate has a long list of features; most importantly, an innovative scripting system called actions. Actions can be used to update all of an album’s tags with a single operation. Yate also supports integration with AcouticBrainz, AcoustID, Beatport, Discogs, iTunes, MusicBrainz and TMDb. All changes can be easily reverted and individual changes can be undone in any order. Whether you want to automatically or manually tag your files, Yate can do it all!

Compatibility: OS X 10.9 or later, 64 bit
