Audio Specification

1. Stereo

   One-dimensional, sound comes from (left/right) the physical location of speakers.

2. Surround

   Filters the existing stereo signal to fill area around the speakers and in front of the listener with sound. Sound sources appear to come from beyond physical locations of the speakers.

3. Multi-Speaker Surround (Dolby Pro Logic or Digital AC-3)

   Uses five speakers instead of two to surround the listener; hence, sound emanates from five directions and creates an engaging audio experience. This audio surround effect is pre-recorded and does not interactive environment.
