What is the difference between .dss and .oga?

Description: Digital Speech Standard (DSS) is a proprietary compressed digital audio file format defined by the International Voice Association, a co-operative venture by Olympus, Philips and Grundig. DSS was originally developed in 1994 by Grundig with the University of Nuremberg. In 1997, the digital speech standard was released, which was based on the previous codec. It is commonly used on digital dictation recorders. Modern phycoacoustical codecs that perform nearly as well at only slightly higher bitrates have led to this speech coding standard being less used in modern voice recording equipment.; OGA is an audio file format that can be created using various compression algorithms such as Ogg FLAC, Ghost, and Ogg PCM. Ogg Vorbis or Speex compression can also be used but it is not recommended by Xiph.Org.
