Everyone wants to hear true-to-life sound when they’re enjoying the latest blockbuster, but how can you tell what sound format will give you ear-splitting, jaw-dropping, mind-blowing audio? Along with the advent of HD video came a whole host of HD audio to match. Blu-Ray discs and players offer special audio formats like surround sound and THX-certified sound. If you find yourself scratching your head when trying to decipher the difference between sound formats, read on.
There are some basic differences between all of the sound formats available for home theaters. Some require, for the best sound, multiple speakers. Others require at least five or seven, which make them surround sound. The two main audio companies that produce the majority of the sound formats for today’s movie DVDs and Blu-Ray discs are Dolby Laboratories and Digital Theater Systems. They are very similar, with two main differences: DTS audio is usually compressed at a lower rate than Dolby, meaning that it will sound clearer once it is uncompressed, but Dolby is more popular and more widely used across the board for both DVDs and Blu-Rays. And within each of these labels is a whole array of different sound formats designed for different experiences.
