			The '''Windows Audio Session API (WASAPI) output support''' component allows you to play your music using WASAPI exclusive mode.

	WASAPI is a new audio output method introduced in Windows Vista; among other things, it provides an exclusive mode that allows applications to take full control over soundcard's resources (muting any sounds played by other applications) and play unaltered bitstream without passing it through the Windows mixer.
