* This news release is only for the Japanese Market.
Olympus Optical Co., Ltd. (President Masatoshi Kishimoto) is pleased to announce the new Voice-Trek DM-1 Digital Voice Recorder. The Voice-Trek DM-1 features a convenient USB interface for PC, as well as a SmartMedia card that can store up to 128MB of voice data, providing a maximum of 44 hours and 40 minutes of recording. It also features MP3 music playback. In fact, it's the world's first MP3 player to feature WOW 3D sound technology from SRS Labs, Inc., which lets users enjoy high-fidelity, three-dimensional stereo sound. The Voice-Trek DM-1will go on sale on June 22, 2001.
As the pioneer of microcassette recorders, Olympus has led the industry in the development of voice recording technologies over the years. These advanced technologies have now been ported to our new IC recorders and other digital recording systems for a variety of applications including recording at business meetings, personal voice memos, converting voice data into text using a personal computer, and others.

Now, with the new Voice-Trek DM-1, Olympus has added the convenience of high-fidelity music playback. Without compromising the recording features that have been essential to business applications, Olympus has created a new product that goes beyond the confines of the business world. It is a personal communications tool fully adaptable to both business and pleasure.

The Voice-Trek DM-1, like its predecessor the Voice-Trek DS-1, employs SmartMedia cards for recording media. As voice data is recorded, it is digitally converted to highly compressed DSS format and written to the SmartMedia card. The Voice-Trek DM-1 comes standard with a 32MB SmartMedia card, which allows for up to 11 hours of recording. Heavy users can use a 128MB SmartMedia card for a maximum of 44 hours and 40 minutes of voice recording. (In both cases, the device is set to Long Play (LP) mode.)

With the bundled USB connection kit, linking the Voice-Trek DM-1 to a personal computer is fast and easy. Voice data files are easily transferred between the two, and voice files can then be conveniently stored and played back on the PC.

The software bundled with the USB connection kit includes DSS Player 4 for DM-1. When used in conjunction with optional voice recognition software (such as IBM's ViaVoice for Windows V8, or Just Systems' "VoiceIchitaro11"), users can convert digital voice files to Japanese text.

But the Voice-Trek DM-1 is not just a voice recorder. Users can also transfer MP3 and WMA- files from their PC to the DM-1 to enjoy music playback. The DM-1 is the world's first MP3 player to incorporate WOW technology from SRS Labs, Inc. This, along with its full-range digital equalizer feature, enables listeners to enjoy high fidelity stereo sound.

Main Features
Digital voice recorder features
Single 128MB SmartMedia card records up to 44 hours and 40 minutes of voice data
The Voice-Trek DM-1 uses high-performance 3V (3.3V) SmartMedia cards to securely store voice data. Adding to the 4MB - 64MB range of the previous model the DS-1, it is compatible with the optional 128MB cards, and delivers a maximum of 44 hours and 40 minutes* of continuous recording performance. The chart below indicates the maximum recording capacity for each of the available SmartMedia cards (4MB - 128MB).

Memory capacity SP mode LP mode
4MB 30 minutes 1 hour 10 minutes
8MB 1 hour 10 minutes 2 hours 35 minutes
16MB 2 hours 30 minutes 5 hours 20 minutes
32MB (included) 5 hours 05 minutes 11 hours 00 minutes
64MB 10 hours 20 minutes 22 hours 10 minutes
128MB 20 hours 50 minutes 44 hours 40 minutes

* 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.

Digital music player features
Maximum 4 hours of MP3 or WMA-formatted music file recording
Users will appreciate the DM-1's ability to play popular compressed file formats such as MP3 and WMA. Download files from the Web, or use the included MusicMatch Jukebox software to copy from your favorite CDs--either way, the DM-1 is ready to play. The standard 32MB SmartMedia card can hold between 25 and 60 minutes of music data, and the optional 128MB card can store up to 4 hours of music.
* Please note that recording capacity varies with the bit rate at which music data is encoded. For the same file format, sound quality improves with higher bit rates, but file size increases, with better sound quality. SmartMedia cards hold less music data when it is encoded at high bit rates.

Memory capacity 160kbps 128kbps 96kbps 64kbps
16MB 12 min 15 min 20 min 30 min
32MB (included) 25 min 30 min 42 min 1 hr
64MB 50 min 1 hr 1 hr 20 min 2 hr
128MB 1 hr 40 min 2 hr 2 hr 40 min 4 hr

Vibrant sound reproduction with WOW technology: a first for MP3 players
Rich, vibrant stereo performance from an MP3 player is made possible by WOW technology from SRS Labs, Inc. of the US--and the DM-1 is the first MP3 player in the world to incorporate it.* Match your type of music or your style of listening with four levels each of surround effects (SRS 3D) and bass effects (TruBass). Natural, three-dimensional stereo, rich bass, and clear high tones are yours to enjoy.
* As of May 31, 2001
When you're playing your music, choose from one of four digital equalizer settings (Rock, Pop, Jazz, or Flat), or set up custom equalizer settings to hear your music the way you want it to sound.

Stereo earphone included
Use the included stereo earphone, which plugs into the DM-1's earphone jack, to enjoy high-quality stereo music wherever you go. (Note: voice recordings can only be played back in monaural mode.)

Other useful features
Alarm functionality
The DM-1 features an alarm that can be set, just like a watch alarm, to ring at a pre-set time. Or, set a voice data file or music track to play when you press any button while the alarm is ringing. Use this handy feature to remind you of scheduled events, or as a stand-in for a trusty alarm clock.

External power source available
The two alkaline batteries provide roughly 11 hours of continuous voice recording. For voice or music playback, battery life is approximately 8 hours. (These figures are derived from Olympus lab tests.) The optional A324 AC adapter allows you to record long events, or enjoy continuous playback without replacing batteries.
