What Is a DSS File?

Overview: DSS File

DSS is short for Digital Speech Standard and is a digital version of an audio file format presented by the International Voice Association. This file format saves and stores the voice audio data in a highly compressed file format.

Compared to standard WAV or MP3 files, a DSS file is up to 20 times smaller. Therefore, it is the perfect file format for transcription files, dictation, and audio voice data in a highly compressed format.

Best Tools for Opening DSS Files

While DSS files may not be as popular as other commonly used audio formats like WAV or MP3, many software apps can open these files. To open a DSS file on your computer, you'll need a specialized media player like Player Standard R2, DSS Player Lite, or Olympus DSS Player.

Here are the best tools to open DSS files on Windows, Mac, and Linux:
