Our take on the Olympus DS-40

by Ralph Graves
Olympus

The Olympus DS-40 voice recorder features a detachable stereo microphone that ensures you'll get great on-the-go voice recordings in any situation. And it includes a built-in MP3 player so you can enjoy your favorite music, podcasts, and even audio books from Audible.com. The recorder's 512-megabyte embedded memory can hold over five and half days' worth of voice recordings.

Recording and playback options
The DS-40 has a built-in mono microphone in addition to its detachable stereo microphone. You can adjust the sensitivity of either mic to adapt to different recording conditions. A low cut filter minimizes the rumbling of air conditioners and machinery while you're recording. Choose the voice-activated recording mode for convenient hands-free operation. For playback, you can either use the recorder's built-in speaker, or plug in the supplied earbud headphones for more discreet listening. The Voice Filter function enhances voice quality by reducing high- and low-frequency noise during playback. And you can vary the speed of the playback, too — great for transcribing.

Smart software helps you manage your recordings
The included DSS Player software lets you manage your voice recordings on your PC. With the software you can transfer recordings from the DS-40 onto your computer, edit them, and organize them for archiving. The software also lets you subscribe to audio podcasts and automatically transfers them to your player when you connect it to your PC.
