This surround sound is also known as 5.1 channel surround sound and also commonly referred to as “AC-3.” This is one of many surround sounds created by Dolby Laboratories (AKA: Dolby Labs; Dolby).
This was a major milestone when this was created because it took Dolby Pro-Logic to a whole new level and is still considered to be the industry standard as a minimum surround sound used in all modern films despite being created in 1992.
What you need for this:
- A Dolby Digital Receiver
- 5 speakers (left front, right front, center, left rear and right rear)
- For even better sound a powered subwoofer is strongly suggested to enhance the bass tones.
