We live in a world dominated by our visual and auditory senses. There is no question that we respond to motion and sound much more readily than static text and images.
Audio/Video production is a large component of most successful multimedia, web, CD/DVD, and video projects. Regardless of the final output-and even if the audio/video project is stand-alone-nothing can hold attention or bring to life your message as effectively. Music and sound effects are the driving force behind the personality of any given multimedia work. If you want to create an emotion in the user, sound is the most powerful influence.
