Is 5.1 dying? Many think Dolby Atmos (which supports 7.1.4 or more) is the future. However, 5.1 remains the most accessible high-end surround format. Most home theater setups are 5.1, and most laptops cannot decode Atmos natively. The FLAC 5.1 file is portable, robust, and plays on everything from a car's media system to a $50,000 home theater.
