The MP3 tag editor is capable of showing technical details about audio files.
To get the details area visible, press "Ctrl" + "I", or check "View" - "Show music info".
mp3Tag is great, by the way. I am a bit of an addict when it comes to music. I download a lot of music files from blogs and many of them are poorly tagged and named. mp3Tag makes the process of making them more useful so very easy. I have hundreds of files from a time before I purchased mp3Tag and am now going through those files to fix them. I simply could not do this without mp3Tag.
Keep up the great work. I look forward to future versions.Randy
