Found this little free reverb - really nice!

My email bounced.
Also, it appears to be VERY old.

Re: commercial convolution reverbs,  there are cheaper ones than Altiverb, although I read somewhere that with Altiverb you are paying for the comprehensive impulse response library as well. 

Yes, I have tried Ambience, but wasn't *all* that impressed. 
Out of the non-convolution free reverbs that I've tried so far, the one that I like the most is GlaceVerb:
http://www.dasample.com/index.php?show=glaceverb
but after convolution I don't think I can accept anything less.
I'm actually pleasantly surprised that my system is even capable of real time zero-latency convolution.

EDIT: Here's another free convolution package: http://freeverb3.sourceforge.net/  There is a VST plugin which supports both Intel and AMD  (no Mac), but I couldn't get it to work in my VST host (Chainer) - might try another host later.

In RevolVerb, I've noticed that some impulse responses don't sound too loud - the wet control can be much higher with the mix sounding ok.  Looking at one of the "good" impulse responses, it has a much lower signal level (circa -20dB), and it's also encoded with 24 bits.

So, I thought I'd try and "fix" one of the bad impulse responses. I converted it to 24 bits first (to retain resolution), and then normalised to -20dB.  This did fix the level problem, however when I listened VERY closely, I could hear a difference.  The specific impulse response I'm testing with at the moment is this one: http://www.impulseresponse.org/Real%20S...hurch2.zip  (the Chicago 2 Micset 1 recording). Using the original, and playing middle G (S Erard, but it probably doesn't matter), I hear a very sharp resonance which occurs about half a second after playing the note. Using the modified version of the impulse response, this resonance doesn't sound anywhere near as sharp - it's sort of "smeared".  So, I've decided that "fixing" the impulses in this manner just doesn't work - I don't think RevolVerb uses enough of the bits in the higher resolution impulse response.

I loaded this same I.R into two commercial products, and this sharp resonance was present equally in both.  I then loaded my modified I.R into the commercial products, and it sounded identical, so I didn't do anything wrong when I processed it.

I think RevolVerb is probably working ok with 16-bit impulse responses that have a high signal amplitude (except for the level problem). I do NOT think it's working 100% for high resolution recordings where the impulse response has not been amplified/normalised to a high signal level. 

Greg.
p.s I think I'll end up buying a convolution reverb.

Thanks for the Freeverb3 link. I think I'll try it. I can't use RevolVerb being on AMD. I am actually using (and liking) an older Directx plugin (not free) Timeworks Reverb 4080L : http://www.sonictimeworks.com/products.php

I've tried Classic Reverb too.  Still not all that impressed.   I have some impulse responses from an old reverb unit from many years ago, and when I load them into a convoluting reverb, it's miles better than Classic Reverb, or any other of these reverbs that I've tried for that matter.  This hardware reverb that I'm comparing with wasn't anything all that special - it's the Alesis Microverb, which was dirt cheap.  The reverb in my digital piano is also very nice, and I'm sure it's not a fancy convoluter.

I still haven't found a VST plugin that does NOT use convolution, but sounds very good.  I'm sure they're out there but I just haven't found one yet.

or this one, called "epicVerb", really nice:

http://varietyofsound.wordpress.com/200...b/#more-10

i can't afford either of them at the moment, but these two packages seem to have a very good reputation amongst algorithmic (not convolution) reverbs:

also, as far as i can tell from the KVR forum, the Ambience guy hasn't been around for a while...

this is an excellent convolution reverb as someone else has already mentioned

one of it's IRs is a 'piano room'. the piano room is true stereo and should be of particular interest to pianoteq players / recorders.

I've found that the chorusing/flanging effect can be removed by simply turning down "modulation" to zero I was noticing this in both epicVerb and Arts Acoustic.

I think epicVerb will be more than enough reverb for me for the time being.

Another convolution based reverb is Voxengo's Pristine Space.
http://www.voxengo.com/product/pspace/

Just a little heads up re: Reflections LE - AFAIK it does not support *true* stereo convolution (which requires *four* channels of convolution), whereas SIR 2 and Pristine Space do.
