Hello

Not sure about the problem :S sorry.
I will implement a WavDest in C# directly without the DLL requirement, but it will be in the future.

Code:

try
{
    waveDest = (IBaseFilter)new WavDest();
}
catch (COMException)
{
    MessageBox.Show("Missing WavDest", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    return;
}

That error is likely to mean that the WavDest filter is not registered.
