AudioGuru will be useful especially when you need to quickly access the information hidden inside MP3 files. Speaking of MP3 files, I mean, and a myriad of other formats (more describe them a little further). The program will detect and display the file compression level, bit rate, encoder version. It will be able to calculate the size of the uncompressed file, from which could have made the study. This audio guru knows how to deal with tags all versions, as well as other information that can be hidden in a file - a picture album, the lyrics.
As I already said, is supported by a great number of files compressed variety of algorithms: AC-3 (ac3), Monkey 'Audio (ape), Windows Media Audio / Video (asf, wma, wmv), Free Lossless Audio Codec (flac), Mpeg Audio (mp3, mp2, mp1), Mpeg 4 (mp4, m4a), Musepack (Mpc), OptimFROG (ofr), OGG Vorbis (ogg), Speex (spx), True Audio (tta), Wave (wav), Audio Interchange File Format (aif), WavPack (Wv).
Tags and data of various kinds are displayed quite correctly: APE v1.0 / 2.0, ID3 v1.0 / 1.1 / 2.2 / 2.3 / 2.4, Vorbis Comment, Windos Media Audio, Lyrics3 v2.00, MP4 iTunes Tag.
Program conveniently integrates into the context menu. Well, the main advantage of it - for free.
