Convolver 2.17 is available via http://convolver.sf.net


Convolver is

* a multi-channel, multi-format 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). See the setup walkthrough for ZoomPlayer after reading this page for further details. Finally, there are a number of

* command line applications for testing performance, and convolving files directly, for example

Features:

* 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 and scaling of both inputs and outputs
* Wide range of impulse file formats accepted (including WAV and raw 32-bit PCM)
* WIndows Media Player plug-in and DirectShow filter interfaces

This release:

* Allows WAV files to be interpreted as filter paths: the source channels are convolved with the corresponding channels of the WAV file.

* Allows a config file to comprise a list of filter path filenames, with automatic selection of the first compatible filter path (by number of input and output channels, sample rate), where a filter path filename is either a text config file, or a WAV file

There are some speed improvements.

This is a VC++ 2005 test build.

There is also new release of rec_imp -- to record room impulses -- on http://www.duffroomcorrection.com
