Probably not, you still are doing inverse MDCT's on the same block sizes.
The savings with smaller bit rates comes in the unpacking, way less bit
reads and decodes...So smaller streams probably require less processor,
there is one savings for bigger streams, the stereo uncoupling doesn't
happen after q5, I think, but that's a much smaller savings than the loss in
the unpacking...
