The freeDSP is an open-source digital signal processor family for the do-it-yourself community. The applications range from active loudspeaker concepts (digital crossovers, bass enhancement, …) and room equalization over advanced musical effect processors to car audio signal processing.
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.
