MP3Test is a tool to validate your MP3 files and detect the ones that contain errors. The program can scan an entire directory, with optional sub-folders and lists all files, indicating their quality and error status as well as the severity of the error. It uses color coding to easily identify the "bad seeds". MP3Test can also perform CRC test (if the file supports it) and verify the integrity using the CRC value as an additional measurement. You can also launch any file in your default player right from the interface. damaged or bad files can be moved to specified directories or deleted.
