Internet music dealers currently sell "CD-Quality" tracks, or even better ("Studio-Master"), thanks to lossless audio coding formats (FLAC, ALAC). However, a lossless format does not guarantee that the audio content is what it seems to be. The audio signal may have been upscaled (increasing the resolution), upsampled (increasing the sampling rate) or even transcoded from a lossy to a lossless format. Lossless Audio Checker analyzes lossless audio tracks and detects upscaling, upsampling and transcoding.
Lossless Audio Checker 2.0 was presented on October 30th, 2015 at the 139th Audio Engineering Society (AES) Convention in New York. More information about our paper is available here.
