Convert audio and backup files (DSS) online for free
The converter easily converts your DSS files to various formats - free and online. No Philips SpeechExec or or other Audio software needed.
To convert other file formats to the "Voice Dictation Audio File" file type, you need software like Philips SpeechExec or a similar tool.
The .DSS file primarily functions as a Digital Speech Standard audio file. It is a highly compressed, proprietary audio format developed jointly by Olympus, Philips, and Grundig for digital dictation recorders. Professionals in legal and medical fields use it to record voice notes, interviews, and dictations.
To open these files natively, users typically need expensive, specialized transcription software like Philips SpeechExec or Olympus Dictation Management System.
The main disadvantage of the .DSS format is its proprietary lock-in. You cannot play .DSS files in standard media players, web browsers, or mobile devices without installing specific audio codecs. Sending a .DSS file to a client or colleague often causes frustration because they will lack the $100+ software required to open it. Furthermore, the format uses heavy compression optimized only for human speech frequencies, making it completely unsuitable for general audio or music.
To make these recordings accessible, you must convert them. For universal playback on any device or web browser, convert the file to MP3 or M4A. If you need an uncompressed format for forensic transcription or long-term archiving, convert to WAV. Drop your file here to view and convert it securely right in your browser with convert.guru.
Note: A small number of .DSS files are Synology NAS Configuration Backups created by Synology DSM, or Hydrologic time series data files for HEC-DSSVue. These are system data files and cannot be converted to audio formats.
Use Convert.Guru to open and convert your DSS file.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DSS converter.
