Convolver is a DSP Audio convolution plug-in for Windows Media Player or any application that accepts DMOs or DirectShow filters. Passes what is being played back through a user-provided FIR (Finite Impulse Response) filter (to provide room-corrected sound, for example).

It will take a set of single-channel impulse response files and convolve them with the input stream.

Why would you want to do this? With a suitable impulse response generated by a tool such as DRC you will be able to play sound corrected for your room response. Read more here.

You will also be able to generate cross-overs, equalizers and other tools that require the source signal to be filtered and redirected to different output channels.
