This plugin enables PCStage to control your default soundcard's playback line levels. Its user interface offers the same Level and Mute controls as the Windows Audio Mixer, but it also accepts commands from PCStage, which can specify smooth level fades.

The commands available are

Level <line> <percent> [<fadesec>] Sets the named line to the given level, which is a percentage from 0-100. An optional fade time (in seconds) can also be given.
Mute <line> [On|Off] Sets the mute state of the named line.

Line names need only be partial (e.g. 'Mic' for 'Microphone'), but must be enclosed in double quotes if they contain spaces.

While fading, the line's level is shown bold to indicate this. Any number of lines can be faded simultaneously and independently. A fade is aborted when another is started on the same line, or the line's level fader is dragged.
