Wanted: Freeverb 2.0 source code

Hello,

I am looking for the source code for the reverb plugin Freeverb 2.0. I
can find the binaries, but the source code I have found is all for an
older version. Apparently the author has taken down his website (used
to be www.dreampoint.co.uk), so I can't get it from there. Does
anybody in here know where to find it?

Thanks,
Jesper

do a google search on "freeverb source" it can be found among other 
places here 
http://www.tux.org/pub/sites/sourceforge/lmuse/lmuse/muse/plugins/freeverb/

you can also get the source distribution for Audacity (audio editor from 
Carnegie Mellon music group) it has freeverb built into it ..and you can 
grab that.

best,
sam

I can't help you with code, but I've heard it uses the
Schroeder/Moorer reverb model so any search for these keywords should
come up positive. You might also be able to find out its whereabouts
from the http://www.musicdsp.com web site.

Unfortunately that looks like the old version I already have. I have
downloaded the plugin itself here:
http://www.sonicspot.com/freeverb/freeverb.html and it has more controls
than there are in the source code I have found.

Thanks, I'll try that as well.

Hi Jesper,

did you try http://tkscript.de/plugins/freeverb.zip ? I'm not sure
which version this is but maybe it helps.

Freeverb is just the standard Schroeder/Moorer reverb with 8 parallel
delays and 4 serial allpasses - pretty basic stuff.

Jesper,

I have Freeverb code that claims to be for version 3. It has the 
following parameters: Mode, Room Size, Damp, Width, Wet, Dry. 
Unfortunately, I don't remember where it's from. Mail me your address 
privately if you'd like me to send it to you.

This appears to be the same as the one I already have.

I know, but this particular implementation has been reported to work rather
well, and I need something that doesn't consume a lot of CPU power. If you
have any better suggestions in the same order of complexity I'm all ears :o)

/Jesper

No I think it's allright as a moderately good reverb. My comment
wasn't meant to express that it isn't good enough to use it, just that
it should be easy to code from scratch if you don't find the source.

The algorithm coding is relatively simple, but tuning all the various delay
lengths for a relatively smooth sound is the part where having the Freeverb
source is nice.  One could spend hours tweaking those parameters to come up with
something decent, so if someone has already done this, it's nice to take
advantage of that.

BTW, I had the source and e-mailed directly to Jesper.

That is exactly what I wanted to use the Freeverb source code for. I'm
rewriting it anyway to suit my needs, but I don't have a lot of experience
with reverb units, nor do I have the ears to do optimum tuning.

> BTW, I had the source and e-mailed directly to Jesper.

Unfortunately I still haven't been able to find the source that is used in
the Freeverb VST plugin I found at
http://www.sonicspot.com/freeverb/freeverb.html. That version has additional
parameters such as high/low frequency damping and others that are not in the
sources I have found so far, but maybe the source was never made publicly
available for this particular version.

Anyway, I think I have found a bug in the Freeverb implementation - or maybe
this bug is what makes it sound good. In any case, it looks like the allpass
filters are not implemented correctly, as they don't have a flat magnitude
response but have comb-filter behaviour instead.

Jesper
