How about the simply named "Stereo
Reverb" by Fons Adriaensen, available at
http://www.kokkinizita.net/linuxaudio/ladspa/index.html (see section
rev-plugins)?
This was one of my first attempts, and I'm currently not very happy
with the result (but it could still be useful). It will be replaced
some time by two new ones based on the reverb used in Aeolus.
That one was specifically designed as a 'large hall' or church reverb.
It has much more controls that the ones visible in Aeolus. I also have
this as a separate JACK application (which is my preferred way of using
it in Ardour), but the source code is not in a state fit for release :-).
Also the Aella convolution reverb announced at LAC2006 is still in
development and awaiting some free time to be finished. While Aella
was originally designed to use real measured impulse responses, it
will include a mode in wich you can 'design' a synthetic reverb that
doesn't need to be natural at all, e.g. a 'gated' or 'reverse'
reverb.
Things in this area will start moving again in a few months when I'm
settled a bit in Italy.

It is libDSP which contains some assembly code that doesn't seem to
compile well with my gcc. I have used the latest stable (5.0.2) which
(according to the changelog) contains "Support for gcc-4.x".
So basically :
1. I will post the error messages tonight (that is, 6 hours from now
for those who don't live in France) so people can see if they had a
similar problem.
2. Is it possible to use libconvolve without libDSP and what is the
impact on performance ?

It builds fine here with gcc 4.1.2. jack_convolve only uses ASM through
libconvolve which can be built using libDSP (which in turn contains some ASM
code)..
Let us see the whole error messages maybe?

Just build it with gcc-3.4.

Why shall I install gcc 3.4 instead of reporting what a majority of
people call a bug ?

Yes. It's a bug.. the gcc-3.4 thing will just get you up and

Hum tough luck... but I'll give a try to see if it was fixed in the
development branch. There seems to be quiet some changes made to the
X86.c file which contains the assembly routines.
Thanks for the tips.

Well, you can always build libconvolve with a naive C implementation of the
algo from libDSP. Have a look at the README (of libconvolve. jack_convolve
simply uses libconvolve).
This is much slower (i'd guess between 50% and 100% slower) but it should at
least compile without problems.
And if anyone feels like handcrafting ASM code, i'm happy to accept patches..
BTW: If everything fails, try Fons' convolution app (JACE)..
