This plugin is a remake of the original VolumeControl by Teamspeak, which only gets API updates and is no longer under development. I will refer to it as 'the original plugin'.
It reduces the volume of other applications when someone (including yourself) in your channel is speaking.
This plugin does only work with Windows 7 or newer due to the used WinAPI calls!
Why a remake and whats different?
The common problems with the original plugin were crashes and the permanent lowering of volume for some applications, especially games with a launcher like League of Legends.
Obviously I can't guarantee a non-crash experience through perfect bug free code, but every feedback is appreciated
To address the permament lowering of volume this plugin works a little bit different than you are perhaps used to from the original plugin.
This is important! If you are using the Windows Sound Mixer to control the volume on a "per application" basis this will obviously screw you, because it will reset everything to the 'master volume' and you should consider not using this plugin!
