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.

At almost every step along the way of your business pracitices and production process you will need to consider, plan for and execute some type of data management. 

Any component you create in a digital format must be considered volatile and unsafe if it has not been duplicated, copied or backed up in at least two places. Three copies at all times is actually preferred. 

Consider all of your files and raw data. Everything from outlines, scripts and storyboards to images, video and audio that was captured into digital formats as well as any graphical elements along with the project files for their manipulation programs. 

We can never stress this enough: BACK-UP EVERYTHING DIGITAL IN TWO PLACES AT ALL TIMES

No hard drive is bulletproof. Never consider a single copy of a digital file to be safe from data loss.
