this sounds correct in theory but the truth is another...
the "problem" is, we can not talk about "baked in ROOM sound" in longer IR's as there is
actually no room sound in the traditional sense, you won't hear any kind of reverb, hall etc.
at least when talking closed micd cabinets.
there is something different and i am trying to find out what it actually is.
i think it's how the mic picks up reflections from the room, the speakers and the whole cabinet itself.
this seems to be a very dynamic and somewhat random behaviour due to frequency buildup and canceling.
can this be simulated with longer IR's, possibly but i guess that's not the whole story, longer IR's might just
be a part of this.
i did some experiments with extremely small rooms and room sizes, this seems to go into the right direction
but there is still something missing.
if you want to try this out, go to the CAB room tab and set the "Room Level to 100%" "Room Size to 1.00"
and "Mic Spacing to 1-5%"
you won't hear any "reverb" but the sound will change drastically, imho to the better, but as i said there is still
room (haha ) for improvement.
the problem is, with this or a similar setting you will lose some clarity and this what does not happen with a real CAB+MIC
setup, you'll get that "3D" sound without losing any clarity.
thinking a bit further, being able to set at which frequency range the room parameter in the cab block will "operate"
might be a proper solution, basically like setting a high/low pass filter but for the "room"
regarding how sound waves travel i think that this should be a "low pass" style setting as, IIRC low frequencies
have more energy than high frequencies, means low frequencies will "remain longer" and affect the signal
more drastically than higher frequencies.
in simple words, adding a very very small "room sound" to the lower frequencies only would be an interesting
aproach and might lead to that "3D, extra clear micd cab sound"
maybe this can be even calculated percentally, where the amunt of "room" is decaying more and more towards the
upper frequency range.
just a few thoughts...
