By using the Voice Playback function, you can skip non-voice parts during playback, and only play parts of the file where there is voice. This feature makes transcribing meeting minutes efficient. For example, if 70% of the recorded file contains speech, you can finish listening to a 1-hour recording in about 40 minutes. Once you finish recording, use Voice Playback to save time and improve playback for transcription.
The recorder also comes with a handy clip stand attachment that can be attached to the rear of the recorder body. The clip stand can be attached to your pocket or notebook, or can be used as a stand to face the recorder towards the audio source, to reduce noise when the recorder is placed directly on a tabletop.
A feature unique to high-end OLYMPUS audio recorders is the advanced TRESMIC 3 microphone system – for the most accurate stereo sound capture possible. It uses two directional microphones for recording high-quality stereo sound, and a third omni-directional centre microphone that picks up the lower frequency bass sound. It increases the frequency response range to 20Hz–20kHz while achieving a natural stereo feeling.
Sla eenvoudig gegevens op dankzij de ingebouwde USB-aansluiting. U hoeft 'm alleen maar in een pc of Mac te steken om de opgenomen spraakbestanden over te zetten van de recorder naar een externe harde schijf. U kunt 'm ook als USB-stick gebruiken om documenten te delen.
