Question: What is the DSS audio format?
Digital Speech Standard (DSS) is a proprietary audio compression format jointly developed by Olympus, Philips, and Grundig. DSS compresses files approximately 12 times, so it is an ideal format for transferring files by e-mail. The DSS compression format also extends the recording capacity of the xD-Picture Card(tm) removable storage media due to the smaller files it creates.
