There are many free programs to play audio and video files. MrViewer however, is a special case. Although the program does not support an extremely large number of file formats (the most commonly used), it can do a number of things that will please the enthusiast. This way you can view detailed technical information for every open file, which is also updated during playback. You can synchronize or even completely replace an audio track, you can save open files in a different format and adjust all kinds of color parameters during playback.
