From Michael Buchberger:
The filter can be used with almost any Windows media player that supports user-defined output filters (e.g. Media Player Classic, The Core Media Player, Zoom Player, RadLight, WinAmp). Supported features: Dynamic ASIO-Driver Selection. Supports up to 24 output channels. Waveformat conversion and detection. Mono, Stereo, Surround modes 4.0,4.1,220.127.116.11,6.0,6.1,7.0,7.1. Sample rates up to 192kHz. Encoding PCM 16,24,32-Bits and PCM Float.
FFT-Spectrum Analyzer. Output volume control for master and separate output channels. N:N channel mapping (i.e. connect each input channel to arbitrary number of output channels). Virtual speaker room (i.e. graphical interface to control volume of each speaker, using 2D-position of user within a virtual room). Spatial FFT mapping feature that moves virtual user, and therefore sound based on frequency spectrum. In order to use the Multichannel ASIO Renderer Filter, just download and install the software. Prerequisite is .NET 4, installed automatically by the setup routine, if not found on the system.
