MP3val is described as 'small, high-speed, free software tool for checking MPEG audio files' integrity, a free software tool to validate and fix MPEG audio files. It can be useful for finding corrupted files (e.g. incompletely downloaded, truncated, containing garbage)' and is an app in the Video & Movies category. There are six alternatives to MP3val for Windows, Linux and Mac. The best alternative is MP3 Diags, which is both free and Open Source. Other great apps like MP3val are wxMP3val (Free, Open Source), MP3 Stream Editor (Paid), MP3 Check (Free, Open Source) and Checkmate MP3 Checker (Free, Open Source).
MP3 Diags is a GUI-based application that allows end-users to identify issues with their MP3 files, fix some of the issues and make other changes, like adding track information. It also lets you "look inside" an MP3 file.
MP3 Stream Editor is an MP3 cutter/splitter/joiner/editor, an all in one tool for MP3s. Main advantage over other audio editors is that you edit (MPEG - MP3) files without decoding and thus quality loss, graphicaly on a 3D sample display easely with a mouse.
Helps to identify in explicit detail MP3s that do not correctly follow the MP3 format. It also looks for invalid frame headers, missing frames, etc., and generates useful statistics. This can be useful when building a high-quality mp3 archive.
Checkmate MP3 Checker is a free program that checks MP3 files for errors. It scans MP3 files to see if the frames are where they are supposed to be, whether the frame headers are correct and whether the frame headers are consistent throughout the file.
