Question: What are the main features of the Olympus DS-4000 Digital Voice Recorder?
The DS-4000 is a digital voice recorder that records in the Digital Speech Standard (DSS) audio format. It uses xD-Picture Card(tm) Flash memory media as removable storage, so the user never has to leave the recorder with a transcriptionist–just leave the memory card. By using larger capacity xD-Picture Card media, the user has the option to dramatically increase the potential recording time of the DS-4000. The DS-4000 offers the ability to edit files in the recorder. File editing allows appending files, overwriting a section within a file, or inserting new recordings into an existing dictation file. Since the DS-4000 is also a mass storage device, it can also be used as a USBjump” drive to transfer files from one computer to another.

The bundled DSS Player Pro for Windows® and DSS Player for Macintosh(tm) software enables the downloading of dictation files to a computer, where they can be archived and where further file editing can be performed. The optional DSS Player Pro PLUS upgrade (for Windows only) enables file joining and splitting, plus an interface with such voice-to-text applications as Dragon NaturallySpeaking® and IBM ViaVoice®. File joining and splitting functions are native to DSS Player for Macintosh; no upgrade is required.
