Olympus DS-2300 Voice Recorder
The DS-2300 is a digital voice recorder that records in the Digital Speech Standard (DSS) audio format. It was created to emulate most of the features of a professional dictation device at a lower cost. It uses xD-Picture Card? 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-2300. The DS-2300 offers a chance 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-2300 is also a mass storage device, it can also be used as an USB “jump” drive to transfer files from one computer to another.
The bundled DSS Player software enables the downloading of dictation files to a computer, where they may be archived and where further file editing can be carried out. The PLUS upgrade enables file joining and splitting, plus an interface with such voice-to-text applications as Dragon NaturallySpeaking? and IBM ViaVoice?
Digital Speech Standard (DSS) is a proprietary audio compression format jointly developed by Olympus, Philips, and Grundig. DSS compresses audio files approximately twelve times, therefore it is an ideal format for transferring files by email. The DSS compression format also extends the length of recording time on the DM-20s’ Flash memory due to the smaller file sizes.
The DS-2300 was created to emulate the features of Olympus Professional Dictation Devices, whose primary function is to record dictation files for transcription. Dictation recordings do not require a wide frequency response because the audio signals they usually are meant to reconstruct (tones produced by a human voice) fall within a relatively narrow band of frequencies.
Accordingly, the DS-2300 makes files that contain only as much audio detail as is necessary to re-create the original signal. By restricting the frequency response, the DS-2300 can create smaller files, which has the advantage of maximizing memory capacity (recording time).
The DS-2300 is not recommended for recording music or interviews intended for broadcast where a broad frequency response would be desirable.
