Digital Sound System (DSS) is a freeware all-in-one player, converter and audio recorder for DOS created by Sergey Sapelin in June, 1996.

It can play and convert any supported input format to any supported output format (see Supported Formats). Also it supports various audio devices which can be used for playback and recording audio. DSS also can read M3U playlist files.

The newer version uses wavetable synthesis to play MIDI music though it requires Gravis UltraSound GF1 patch files or SF2 SoundFont which are not included.
