When I use Audacity, why does every plugin show up twice in the
effects list? Looking on my hard drive it looks like the plugins are
only installed in one place, /usr/lib/ladspa, and they all come from
either swh-plugins-0.4.14-1mdk or tap-plugins-0.7.0-2mdk.
Thanks.....

I have this same problem.
I have this same problem.
I call it "stuttering plugins".
I call it "stuttering plugins".
I was told that it is caused by having /usr/local/lib/ladspa set up as a symlink to
/usr/lib/ladpsa, but I don't have anything in /usr/local/lib/ladspa at all, and
it's not a symlink, so that can't be it.

I should point out that the "listplugins" utility only shows ONE version of each
plugin. It does not stutter.
Neither does jack-rack seem to stutter. I get one listing for each plugin in jack-rack.
However, Ardour2 shows stuttering LADSPA plugins. I guess Audacity does too.

I'd love to know how to fix it, but for now it is just mildly annoying.

I looked for that just now with 'locate ladspa' and found no
such symbolic link. But, I did find /etc/profile.d/ladspa.csh
and /etc/profile.d/ladspa.sh, each of which set LADSPA_PATH in
the environment. I had my LADSPA_PATH set to /usr/lib/ladspa/
and I don't set that in my shell's RC files anywhere. I unset
LADSPA_PATH in my environment and found that now audacity finds
only one copy of each plugin.
I should point out that the "listplugins"
utility only shows
ONE version of each plugin. It does not stutter.
With LADSPA_PATH set, then listplugins finds one copy of each
plugin. With LADSPA_PATH unset, then listplugins complains about
that and finds zero plugins.
Neither does jack-rack seem to stutter. I get one
listing for
each plugin in jack-rack.
I haven't looked with jack-rack.

guess Audacity does too.
Yes, I've seen that as well.

I don't know that unsetting LADSPA_PATH could be considered a
fix. But, it does seem to reduce the annoyance. I say it's not
a fix because I would think a fix would show the right number
of plugins in applications like audacity and with ladspa's own
listplugins.
Interesting.....

Just a hunch (I have developed both LADSPA plugins and a host):
The problem may be due to the fact that some hosts have hard-wired
defaults for plugin locations. This makes them work for the default
case (plugins in /usr/lib/ladspa) even with no LADSPA_PATH set.
However, if it is set, the host may iterate over its hard-wired path
*and* the paths found in LADSPA_PATH, thus resulting in visiting
each plugin more than once. If this is indeed the cause, the fix is
to amend the host to drop duplicate paths from the merged list
of paths (from hard-wired paths and paths from LADSPA_PATH).
Or not use its hard-wired path at all if it finds LADSPA_PATH set.
