Razer Surround works through Razer’s Synapse 2.0 utility, so you’ll have to register for a Razer account and download the requisite software before getting started. When you finish installing Razer Surround on your PC, the software creates a virtual sound card (called the Razer Surround Audio Controller) that accepts surround-sound data from whatever is running on your PC—games, movies, or music—and emulates it virtually on a pair of stereo headphones.
Log in to Synapse, and ‘Razer Surround’ should appear on the list of Razer peripherals attached to your PC. Click that entry, and you’ll run through a simple calibration process that lets you tailor the positioning of the emulated surround sound to your preferences. The calibration process itself is a little confusing: You have to look at a diagram of where a given sound effect is meant to emanate from, and then close your eyes and adjust the effect’s positioning with your mouse wheel until it sounds like it’s coming from the correct spot.
