I believe the operation "linear convolution" is a sufficiently well-known and well-defined operation in mathematics that no further explanation is required, anymore than the definition of a cos() function. It is defined in many texts on math/DSP.

I will add an "informative" link to a page which can help guide implementors to practically implement this well-defined mathematical operation. I am happy also to point to working, cross-platform, well-optimized code having a non-restrictive license. I can also point to an alternate implementation "Freeverb":
