What is an "omni" microphone and can it improve my camcorder's sound quality?
An omni-directional microphone really is the most general of all microphones. It takes in sound from every direction, omni-directional. It's great for crowd noise, it's great for just general recording, but it may not be the right choice. There will be other microphones that you're going to have to choose from as well. But if you're looking for just a good general microphone something to have around that's going to outperform the microphone that might have been built into your camera an omni-directional might be the choice. One of your other choices for microphones is a hand held. And you'll see this alot especially in movies. If you have a reporter it's one microphone typically shared between more than one person. And a hand held mic allows that sound to move around. So if you've got an interview with two or three people they can all take the microphone. It's the best way to get sound probably in a situation where you have very little control over what's going to happen with the sound. You giveyour reporter or you give the person that's on the camera the microphone they can pass it from person to person and you don't have to worry about having them all miked up individually.
