Yet Another (WA)SAPI New Technology (YASAPI/NT) Output for Winamp
Yet Another (WA)SAPI New Technology (YASAPI/NT) Output Plugin for Winamp utilizes the "Windows Audio Session API" (WASAPI). WASAPI's exclusive mode for rendering audio is a native way on Windows to render audio undisturbed, similar to Steinberg's "Audio Stream Input/Output" (ASIO). The YASAPI/NT output plugin may serve as a replacement for any other Winamp output plugin.
You'll need a GTK runtime for Winamp you might download from https://sourceforge.net/projects/yagtk-rt/files/.
