Make Your Video Sound OutSkip the built-in microphones to get better audio quality.

YouTube has helped act as the great leveler between large and small businesses when it comes to distributing thought leadership and viral marketing videos online. Anyone can start up a channel and upload a video for mass consumption, and these days it seems as if everyone is, with more than 20 hours of video reportedly being uploaded every minute to YouTube. But not all videos are created equally.

With the advent of cheaper and more powerful consumer video cameras, many improvised videos created by enterprising small businesses offer excellent visual results. Sound quality, however, is an entirely different story. One of the biggest mistakes amateurs make when producing videos for online consumption is sticking with the built-in microphone on the video camera. The results can vary, but they're usually bad: full of echoes, too-quiet voices, distracting background noise and garbled speech.
