Purpose and user

The Olympus DM-720 is a 4GB digital voice recorder built for professionals who need reliable capture in meetings, interviews and field work. Its Tresmic three-microphone system combines directional and omnidirectional elements to record a wide frequency range with depth and fullness. The linear PCM option at 48 kHz / 16 bit preserves detail for demanding audio tasks.

Build and daily use

A smart metal body houses the controls and microphones in a compact form that fits a pocket or bag. The zoom microphone function lets you expand or contract the pickup range using the plus and minus buttons, which helps in noisy rooms or when the source is at a distance. An easy-to-use interface and extended editing operations support quick review and marking on the device.

Limits of the format

Internal storage is fixed at 4GB, so long sessions in high-quality linear PCM will fill the memory faster than compressed modes. There is no card slot mentioned, so you cannot expand capacity or swap media in the field. File transfer requires a wired connection to a computer, which adds a step before sharing or archiving recordings.
