I don't think I've seen this discussed here, but for those of us with older M processors room correction is possible for PC based sources. One solution for for Logitec's Squeezebox may be found at www.InguzAudio.com.

Of course I doubt anyone with MRC would have bothered to implement this, but I'm wondering what the comparision between MRC and Inguz/DRC would be at least from a theoretical perspective.

Papers on MRC talk about how their solution differs, by only looking at the lower frequencies, in particular 'room modes' where resonance is introduced and specifying a few notch filters to rectify.

The Squeezebox solution in contrast looks at the whole frequency spectrum, and whilst not doing a crude equalisation inversion, does I believe adjust the whole curve - I think a bit like a glorified graphics equaliser.

I'm still struggling to get this working on my system, but meanwhile I was wondering what thoughts people here might have.
