If during manufacturing of an audio soundtrack there is an analog stage (recording to a tape or to a gramophone 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.
Advanced audio corrector allows to remove the phase distortions in high-quality audio files (WAV, 16-bit Stereo) before coding to a format MP3. The program works in a batch mode.
