MP3Info is an MP3 technical info viewer and ID3 1.x tag editor. It has an interactive mode (using curses) and a command line mode. A separate executable includes a GTK-based GUI version. MP3Info can display ID3 tag information as well as various technical aspects of an MP3 file including playing time, bit-rate, sampling frequency, and other attributes. It can output this information in a pre-defined or user-specified format.
