Pretty sweet. This is on Windows 7 by the way, with Realtek HD audio. I did a quick google on it and couldn’t find anything on it. Such a sweet feature! I like to keep it on Concert Hall for music XD. Could be good for parties.
There are also many other enhancements besides environment, like digital surround-sound which is sweet.
To get to it:
Right click the speaker icon on the taskbar.
Select ‘Playback Devices’
Click on ‘Speakers’ and click the ‘Properties button’
Go to the ‘Enhancements’ tab.
It’s good to select ‘Immediate Mode’ for easy recognition for the differences between enhancements.
