Help wanted building DSP plugin for Windows Media Player 10

Convolver is project to build a DSP plug-in for Windows Media Player.that will read an impulse response (wave file) and convolves it 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. For more details, see Ed Wildgoose's Duff Room Correction site.

At this stage, the code is just Microsoft's Echo Sample, which is an adaptation of the default audio DSP plug-in generated by the Windows Media Player Plug-in Wizard.... read more
