DC-DSP Filter is build around the DC-DSP Components. It is a Microsoft DirectShow audio filter which is able to process 8/16/24/32 bit integer PCM and 32 bit IEEE float audio data. It works on every Windows platform with DirectX 9 or above installed.

The DC-DSP Filter is released under the Mozilla Public License 1.1. Some of the components are based on sources under different licenses (GPL/WOL). These licenses are explicitly mentioned in the headers of these filters.
