This should be of interest with this thread.
New software from Sonarworks:
Sonarworks Systemwide for Windows and macOS. Systemwide will take all audio and apply Sonarworks calibration to it.
Select it as your primary output device and anything you playback will end up being calibrated.
Spotify, Youtube, Bandcamp, iTunes… Listen to reference tracks from anywhere and compare properly, having the same reference sound. And never hear the old uncalibrated sound ever again!
