What is a DSS file?
The Digital Speech Standard (DSS) is a proprietary compressed audio file format defined by the International Voice Association (IVA), a joint venture between Olympus, Grundig, and Philips. Released in 1997, it utilizes a lossy compression algorithm optimized specifically for human voice frequencies to enable high compression ratios for digital dictation recorders. The format supports metadata headers for dictation workflow (e.g., author ID, work type) and allows for overwrite/insert recording modes, distinguishing it from standard linear audio formats.
How to open a DSS file
DSS files are designed for proprietary transcription software such as the Olympus DSS Player or Philips SpeechExec. For general playback without purchasing professional dictation software, the VLC media player (v2.0+) offers partial support. However, for full compatibility and metadata access, users often need to convert the file to WAV using the free 'Olympus DSS Player Lite' or similar vendor-supplied utilities.

What is a WMA file?
Windows Media Audio (WMA) refers to a series of audio codecs and their corresponding Microsoft container format, designed as a competitor to MP3 and RealAudio. The standard WMA codec is lossy, but the format family includes WMA Lossless, WMA Pro (multichannel), and WMA Voice. It utilizes the Advanced Systems Format (ASF) container structure and supports digital rights management (DRM), which historically restricted playback to authorized Windows devices.
How to open a WMA file
WMA files are native to the Windows ecosystem and open by default in Windows Media Player and Movies & TV. macOS users require third-party components like Flip4Mac (legacy) or universal players such as VLC Media Player and Elmedia Player to decode the stream. Android and Linux support is generally provided via VLC or by installing ffmpeg-based media libraries.
