Waves NX is a virtual monitoring plugin that lets you hear the acoustics of a high-end mix room over headphones. It tracks your head via your computer camera to optimize the sweet spot, and allows you to monitor either in stereo or in 5.1 surround on your regular stereo headphones.
NX attempts to bridge the gap between monitoring on speakers and monitoring on headphones so that you no longer have to worry that what you’ve mixed on headphones will sound different once you switch to speakers. The plugin lets you hear the same natural depth and stereo spread on headphones that you would hear on external monitors so there's less need for cross-referencing between the two.
Waves NX works on most DAW apps on both Mac or PC. Nx requires a webcam, and will support any webcam that works on your system. It's available at an introductory price of only $49. Check out the Quick Start tutorial below.
