Do you mean the defaults that are displayed by analyseplugin?
If so, I wouldn't call that a preset, in that it is a single
set of default parameters provided exclusively by the
author.

You may be correct in theory, but the top search hits suggest
that practice is otherwise:

In this third hit on Google, titled "LADSPA Vocal Effect Presets"
the author is distributing his parameter settings as screen shots.

http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=0ahUKEwjPn5zw_rjMAhVD32MKHXpmDpUQFggpMAI&url=http%3A%2F%2Flinuxaudioblog.com%2F%3Fp%3D262&usg=AFQjCNH_rrbcFwo7EdO-62gjvfpeIp7ttg&sig2=Ns7qj1KsjsZwkUgxclMO1Q&cad=rja

Another hit is Guitarix documention, describing differences
of Guitarix and LADSPA plugins.

https://sourceforge.net/p/guitarix/wiki/How_to_use_the_new_ladspa_plugins/

        Simple LADSPA plugins can just be added to a track, maybe
        some parameters adjusted, and you are done. In contrast, the
        Guitarix plugins need a preset file which is generated and
        modified by Guitarix, and the meaning of the 5 assignable
        LADSPA parameters depend on the settings in the preset.

The audacity docs also rank high. This is important because
Audacity is so widely used.

http://manual.audacityteam.org/man/effect_menu.html

        LADSPA effects support real-time preview. They do not
        support import/export of presets but do support saving
        presets for use in Audacity only.

Another part of the Audacity manual says:

        Many VST effects support import and export of named factory
        presets in a single FXB file, but LADSPA and LV2 effects do
        not support import and export of presets at all.

So if there is a standard for exchanging plugin parameter
sets, I haven't seen it, and it is invisible to Google
(invisible == not appearing on the first page.)

Almost everyone who uses a DAW for audio production has
their own sets of preferred plugins and parameter settings.
Where are these being shared?

Can we do better?
