This program checks the origin of APE, FLAC, SHN, WAV and LPAC files. In most cases, it will be able to determine whether or not a lossy encoding has been applied (i.e. converted from other lossy encoding formats, such as MP3). Files can be added from a directory, as individual files or as tracks from an audio CD, and the results appear in a summary panel and a detailed event log.
The program uses a method called auCDtect developed by True-Audio Software. The result obtained by Audiochecker is the result of their software. The package already includes the console decoders it needs (Monkey's Audio, FLAC, Shorten, LPAC) together with auCDtect, and it runs without installation. Audiochecker is freeware, version 2.0 beta is the last release, and the program is no longer developed.
Audiochecker helps users find out whether lossless audio files were made from a lossy source such as MP3.
