Open DS2 File
The DS2 extension is used primarily as an audio file created in the Digital Speech Standard Pro (DS2) format, which is where the extension stands for.
Digital Speech Standard Pro is an evolved development of the DSS format, which uses the same file compression technology, however DS2 also provides an encryption feature.
File encryption is provided in 128/256-bit AES, allowing user-created files to be protected, which is important for sensitive audio data.
DS2 is a highly compressed audio format developed by Olympus for digital voice recordings.
The DS2 typically contains a recording of human speech that is saved to the memory card of a recording device.
The DS2 is used to store personal and professional notes, often by judges, lawyers, prosecutors, investigators, and doctors.
The DS2 is useful for sending as email attachments due to the highly compressed file size.
The DS2 format supports better sound quality, which in turn improves speech recognition results.
Importantly, DS2 files can be converted to standard WAV files using DSS Player Pro.
DSS Player Pro is a software application that is included with the purchase of some Olympus digital voice recorders.
DS2 files can also be converted with Voelker Software's DSS File Converter.
