Experience versatile recording with the built-in stereo microphones, providing Beamforming noise reduction, Dictation and Conference modes. Tailor your recording experience further by selecting from three microphone sensitivity options. Opt for High sensitivity for crisp conference recordings, choose Mid for effective dictation, or select Low for optimal up-close recording.

Low-noise microphone unit

The DS-9100 incorporates low noise omni-directional microphones. The built-in shock absorber covers the microphone unit, reducing handling noise from the body.

Studio grade pop-filter

The microphone housing includes a triple layered pop-filter, which helps block the wind noise and plosive sounds when speaking into the microphones.

Beamforming noise cancellation mode

The Intelligent Two-microphone System utilizes the omni-directional microphones, analyzing phase differences from sound sources. Using our unique Audio Beamforming algorithms, the DS-9100 suppresses sound from specific directions, reducing noise from the back and sides significantly, focusing on the speaker during dictation. This dramatically improves sound quality for speech recognition, even in challenging environments.

Dictation mode

For classic dictation of your notes or reports, the main microphone will be recording in an omni-directionality mode so that the recorder can be held in various positions.

Conference mode

Designed for interviews and small meetings, conference recording controls the directionally of the 2 microphones into a 90° layout, which enables high quality recording in a realistic stereo capture. Regardless of where the person speaking is located or the direction of speech, you can clearly capture the information.

Supported audio formats

The DSS format promises effective compression without compromising quality in digital voice capture. . The digital speech standard (DSS) allows for quick file editing (insert, overwrite, append, erase/cut) and uses meta information (index, verbal comments, worktypes, etc.) to facilitate collaboration and automatic processing. PCM format, with its minimal compression, ensures exceptional quality as well as compatibility with a variety of playback tools. Simultaneously, the widely utilized MP3 format serves as an excellent choice for storing consumer audio and enables easy transfer/playback of music on digital audio players.

Noise activated recording with VCVA

The VCVA function efficiently manages memory by pausing recording during quiet intervals and automatically restarting when it detects sound exceeding a preset threshold. This feature optimizes playback efficiency and prolongs recording time.

Index Marks

While recording or playing back, you have the flexibility to insert up to 32 Index Marks into an audio file. These marks act as handy indicators, helping you identify crucial or noteworthy segments of your dictation.

Insert and Overwrite recording modes

Unlock different recording options with the DS-9100. Use Insert mode to seamlessly add recordings into existing audio files without the need for additional addendums. Overwrite mode enables you to record over previous dictation at any chosen point. Lastly, Append mode effortlessly adds a new recording to the end of an existing file. With the addition of the New File creation button, you don’t need to start a new recording until you are ready.


Audio file security is crucial for medical and legal industries due to the sensitive nature of the information they handle. In healthcare, patient confidentiality is paramount to comply with HIPAA regulations, safeguarding patient data from unauthorized access. Legal industries require secure handling of client communications and evidence to maintain attorney-client privilege and uphold the integrity of legal proceedings. Ensuring audio file security protects sensitive information, maintains trust, and prevents legal liabilities.


The DS-9100 provides added security with 256-BIT AES encryption* when utilized alongside the DSS Pro file format, ensuring user data remains protected from unauthorized access, enhancing confidentiality, and complying with industry standards for secure audio recording.
*When used in combination with ODMS Cloud or ODMS R8 On-Premise solutions.
