Many studies have proven that online video is much more popular than audio files, even if the video is simply still images. Plus, video is more likely to be shared.
Video can have a dramatic effect on spreading your message, increasing tune-in, and driving ratings. That's especially true in a PPM market. Listening to encoded audio results in rating credit.
AudioLogger's audio to video feature adds a waveform element to give the video movement. Other online services charge a premium just to provide this service, but it is included as a feature for Gold subscribers.
