Recording duration may exceed battery life in some cases. To ensure uninterrupted performance, use of the optional A324 AC adapter is suggested. Also, the recording capacity given here was measured with continuous recording. When recording is done intermittently, maximum recording times may be shorter than the figures given here. |

Bundled USB connection kit links to PCs quickly and easily
The DM-1 is fully compatible with the industry-standard USB interface. With the included USB cable and DSS Player 4 for DM-1 (abbreviated below as DSS Player) utility software, users enjoy high-speed data transfer to and from their PCs. Once voice recordings have been transferred to it's easy to send voice files to friends and colleagues as e-mail attachments. * What's more, the USB connection also complies with storage-class, users can also use the DM-1 as an external storage device.

This product does not come with any e-mail software. Digital sound files from the DM-1 can be played back using DSS Player-Lite, which is available as a free download at the Olympus web site. DSS Player-Lite must be installed in the PC on the receiving end as well, in order to exchange voice mail. |

Lightweight, compact design features superior ease-of-use
The DM-1 has the large operation buttons and simple button layout . A new, large backlit LCD enhances the user experience. Each of the most commonly accessed functions, such as record mode switching, microphone sensitivity setting, and button lock (Hold) , works independently. This makes operation truly simple. The stylish metallic green casing enhances the DM-1's form factor. Incorporating newest DSP from Texas Instruments Japan inside of the body, the DM-1 also realizes lightweight and compact design without sacrificing multi-function performance.

High-fidelity recording (digital voice format delivers high quality in a highly compressed package)
In Standard Play (SP) mode, the DM-1 captures the 300-5,000Hz frequency range. The DSS* digital voice file format allows for the same recording quality and length** as a comparable WAVE file at approximately one-twelfth the file size. And, because the format is all-digital, the user has instant access to any stored file at the touch of a button.
| * |
DSS stands for Digital Speech Standard, an industry-standard file format created through the collaborative efforts of Olympus Optical Co., Inc., Philips (Netherlands), and Grundig (Germany). |
| ** |
At the same level of recording quality, an uncompressed WAVE file is roughly 12 times larger than the corresponding DSS file in Standard Play mode (when measured in KB). In Long Play mode, the WAVE file is approximately 20 times larger. |
|
Automated transcription of voice files (using voice recognition software)
With the bundled USB connection kit, and optional voice recognition software (such as IBM's ViaVoice for Windows V8, or Just Systems' "VoiceIchitaro11"), users can efficiently convert sound files captured in Standard Play mode into a written document format.
| * |
Please note that voice recognition software requires enrollment with an individual's speaking patterns. Current technology in speech recognition software is, as a rule, not suited to the accurate transcription of meetings in which multiple speakers converse using widely varying modes of expression. In such situations, background noise can also hamper attempts at accurate software transcription. |
|
Index marking
By manually entering index marks into a voice file as it records or plays back, users can easily revisit portions of particular interest. Index marks can also be removed from a file at the user's discretion.
|
Voice activated recording (VCVA)
The DM-1 features VCVA (Variable Control Voice Actuator) technology, which can be set to start recording at the sound of a speaker's voice, and to stop recording after the speaker has finished talking. This allows users to maximize storage space and to minimize playback time, contributing to more efficient usage. The digital mechanism that starts recording is extremely sensitive, so losing the first few words of a speaker's voice is virtually a thing of the past.
|
Convenient three-folder file storage
Recorded voice files can be stored in any one of the DM-1's three convenient folders. Because folder names can be modified directly from the DM-1, or by using the DSS Player software on an attached PC, organizing files either by work type, by importance, or by other criteria is a straightforward task. Each folder can store up to 199 individual data files.
| * |
Please note that file names entered directly in the DM-1 may consists of up to 8 English letters/numbers and spaces only. Entry with the DSS Player allows for these and Japanese katakana entry as well. |
|
Fast playback functionality
By depressing the playback button continuously for more than 1 second during normal playback, users can listen to recorded files at 1.5 times faster than the normal playback speed. Digital processing allows to play back files at high speed with zero distortion, so this is convenient to check the content of a recorded file quickly.
