MP3Test – a software to check MP3 files for errors. The software automatically transfers all the damaged music files to the appropriate list and displays the error percentage of each song, their quality, size and path to a file. MP3Test shows the histograms for each song where the percentage of damage and errors is displayed in different colors. The software divides songs into the damaged and error-free file lists that can be sorted by name, duration or percentage of errors. MP3Test allows you to listen to the song in the player by default, move or delete the music file, copy the entire list to the clipboard and view the detailed information about each individual file. The software supports the rename of files in batch mode by taking into account their metadata and tags. MP3Test also contains tools to customize the software for the user needs.
