I agree that we could do with better reverbs.
None of this is to be taken as a diss on Freeverb or Gverb. They still sound
better than my old quadraverb!
I'm not particularly technical, so I'm reading this thread with some interest.
Now you have mentioned it I do notice these behaviours, like the centre field
being 'unrealistically' as wet as the edges and stereo separation which is
tantamount to half of the notes being in one ear and the other half in the
other, drum kits and pianos in soundfonts sprawl all over the stereo field.
With reverbs there are issues of 'translucence' - I want it, but what the
heck _is_ it? There's a natural randomness factor that I'm listening for. I'm
not content with my synths sounding like a stylophone in a dustbin.
Here I'm just going to pay attention and take notes. There is a certain school
of engineering which goes for naturalistic reproduction and I'm not worthy to
even patch your outboard effects. So, as a humble student I would say that it
doesn't have to be 'realistic'. Over-the-top reverbs have their uses,
however, they do have to be pleasing to ear. I guess I'm not going to be
surprised if you tell me that's best achieved by following naturalistic
principles too, but surely we don't _have_ to try to reproduce the room?
I want a virtual forest please ;-)
