Lossless Audio Checker

Lossless Audio Checker is a utility to check whether a FLAC or WAVE file is truly lossless or not, by detecting cutoff frequencies. It can show you the full frequency range for each file. Nowadays, the process of audio mastering sometimes upconverts, upsamples and upscales songs, resulting in CDs and so-called "lossless" tracks that are in fact, incomplete. Lossless Audio Checker helps you identify these tracks. The goal is to raise awareness on these bad practices from the music industry and pressure them to deliver true lossless music. Help us by testing your music and reporting your results.
