The overhead will indeed be large. In terms of using it as a polishing application (master reverb), it's already too late. You could use the convolution program to apply an impulse response function, but you wouldn't want to use it in the way I've designed because you already have parts going into the left and right channels. Applying two different impulse response functions to each channel and recombining them will comb-filter the results (again if you've already done it), hence color the sound, perhaps a lot. I have actually been trying to determine if I could use this as a post- processor to make CD recordings easier on my ears, but all the attempts I've made so far color the sound more than I'd like, even with large absorption factors (corresponding to very short t60's).
