Introduction

With the arrival of DVD the interest in Dolby Digital 5.1 and later DTS has increased significantly. In this series of articles we will cover a variety of topics including what’s required to take full advantage of the multi-channel soundtracks when using headphones, 2, 4, 5.1 and 6.1 speaker systems with the clear focus being on using the PC as your entertainment center. We will also be going through the more well known virtual surround sound technologies available. In this article we will in some detail cover the surround sound formats available for DVD movies as well as DVD audio discs.

The other articles in the DVD series are DVD Buyer's Guide, Virtual Surround Sound Technologies, Stereo to 4 or 5.1 Expansion and The Advantages of the Center and LFE channels. We will not cover the image aspects of the DVDs.
