- a DSP plug-in for Windows Media Player 10. The install package also contains
- two DirectX/DirectShow filter versions ConvolverWrapper or the equivalent ConvolverFilter for Adobe Audition and other applications such as Zoom Player Pro and TheaterTek 2.2, or J.River Media Center (when used with the DirectX host plug-in). Finally, there are a number of
- command line applications for testing performance, and convolving files directly, for example.
Why would you want to do this? With a suitable impulse response generated by a tool such as DRC (http://drc-fir.sourceforge.net/doc/drc.html
) you will be able to play sound corrected for your room response. ; For more details, see Ed Wildgoose's http://www.duffroomcorrection.com
Moreover, you can use Convolver to do bass management, feed cross-overs or equalizers, create an almost binaural effect from a 5.1 movie track, or in any other setup that require convolution.
- Performance is already very good, and subject continual improvement
- Arbitrary-length convolutions (1 million tap limit imposed only as a sanity check)
- Multiple channel input and output, PCM and IEEE Float
- Mixing, scaling and delay of both inputs and outputs; attenuation of source
- Wide range of impulse file formats accepted (including WAV and raw 32-bit PCM)
- WIndows Media Player plug-in and DirectShow filter interfaces
The code is, at present, of alpha quality. I would welcome help with testing, suggestions for features (or help with implementing them!) and with optimization.
