For a typcal stereo room simulation, what you need is actually

| L' |    | a   b | | L |
|    | =  |       | |   |
| R' |    | c   d | | R | 

where a, b, c, d are the responses to be convolved with. 

In its present form, you code will do this if you split inputs
and recombine outputs, but only with a lot of redundant work.

It could be a good idea to have a more flexible I/O configuration
that would allow this.
