The DM-720 from Olympus is a digital recording device capable of storing files in Linear PCM (WAV) formats as well as MP3. It can operate at sample rates up to 48 kHz and resolutions up to 16-bit. Lightweight at 2.5 oz, it's a compact and portable recorder with a Tresmic three-microphone system for capturing a full and detailed stereo sound. An included USB cable allows you to connect to computers directly and recharge a NiMH AAA battery sitting within its enclosure—should you opt for a rechargeable battery over its included alkaline one. Lastly, its transcription, voice-balancing, and voice-playback modes render the unit quite useful in note-taking situations, such as business meetings or interviews.
