What is a DSS file?
The .DSS file extension primarily stands for Digital Speech Standard. It is a digital audio format used by professional dictation machines from Olympus, Philips, and Grundig. The format stores highly compressed voice audio for efficient medical and legal transcription.
However, a .DSS file can also be a DiskStation Backup Configuration File. These files are created by Synology NAS devices to store critical system settings, users, and network configurations. Less commonly, the extension is used as a hydrologic data storage system file for HEC-DSSVue, an emulator save state for the DraStic DS Emulator, or a digital video surveillance file from AVerMedia.
How to open DSS files?
Because a .DSS file has multiple possible meanings, viewer.online/dss analyzes .DSS files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If you know your file type, you can use dedicated software. For audio formats, install native transcription software like Philips SpeechExec. If you have a Synology backup, you must import the file directly into the Synology DiskStation Manager control panel. Hydrologic time series data requires the HEC-DSSVue application to view.
File conversion
If your file is a dictation audio format, you may need to convert it to play it on standard operating systems. We recommend file conversion to sensible target formats like .MP3 or .WAV on convert.guru. Note that system configuration backups and emulator states cannot be converted.
Summary
viewer.online/dss directly opens and previews .DSS files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
