Audio Overview
Audio in media consists of spoken dialog, off-screen narration (voice-over) sounds effects, environmental or background noise and music.
Audio is often considered secondary to the importance of the moving image. Making the assumption that audio is not important is a grave mistake. An old adage challenges you to watch TV with the sound turned down; this would quickly prove the importance of all types of audio from dialog to music and sound effects.
One of the easiest ways to either retain or increase production value in your media projects is to consider, provide for and capture high quality audio.
