Convolver is an open source, high performance Windows application for applying finite impulse response (FIR) filters to multi-channel digital audio in the form of
- a real time DSP audio plug-in (DMO) for Windows Media Player. The install package also contains
- two DirectX / DirectShow filter versions — ConvolverWrapper or the equivalent ConvolverFilter — for Adobe Audition and real time applications such as Zoom Player Pro, TheaterTek 2.2, Windows Media Player Classic, J.River Media Center (when used with the DirectX host plug-in), or Console. See the setup walkthrough for ZoomPlayer after reading this page for further details. In many cases the DMO will also work.
- a VST plug-in version (convolverVST). Finally, there are a number of
- command line applications for testing performance, and convolving files offline, for example. convolverPipe can filter SlimServer playback.
Convolver will take a set of FIR filter files (sound files) and convolve them with sound paths mixed from the input channels, mixing the results into a set of specified output channels.
