Here's the information you need:

If during manufacturing of an audio soundtrack there is an analog stage (recording to a tape or to a vinyl disk in an analog mode), an inevitable consequence will be the appearance of a phase shift between stereo-channels. In an uncompressed soundtrack these distortions are inaudible, but only become apparent when stored in a compressed format (for example in MP3 Joint Stereo). These distortions are heard as unpleasant high-frequency sounds. This program allows you to remove the phase distortions in high-quality audio files (WAV, 16-bit Stereo) before encoding to a format MP3.
