Secret Sounds

The Consumer Electronics Show doesn't start till next week, but there's already some cool releases starting to roll out. We're especially looking forward to Olympus's LS-10; one of the only digital audio recorders that works with a wireless remote. Place the recorder on a speaker’s podium, for instance, and the infrared remote starts it from across the room.—Lauren Aaronson
