Important note: As of November 2021, Waves Audio no longer sells or supports the Nx desktop standalone application for Mac and PC. Click here for more information.
For an optimal 3D audio experience on headphones, you can customize the Waves Nx apps (Windows/Mac and mobile) to your personal head measurements, following these steps.
Nx factors your precise head dimensions and the distance between your ears in order to calculate the inter-aural delays (ITD) and the filters and gains (ILD) for each ear. These are used to approximate your individual Head-Related Transfer Function (HRTF). The default settings of the Nx app are based on average data for the adult human population, but for optimal experience you can adjust them to your personal dimensions.
