Even most of the hardware ones are utterly useless (see "[LAD] vu-meter

The goniometer(TM) aka Stereo Phase Scope is not a jellyfish display. JF
would be a surround 5.1 variation.

I was actually positively surprised how much information is displayed by
a goniometer. It takes a while to learn to read it, but it's amazing.

We (Chris, Axel and I) went through various stages including
video-taping the LV2 plugin display in order to improve readability and
usefulness. The default preset is very close to that of a DK-Tech MSD600

'locate to peaks' is a very nice idea. However I'm not aware of any
plugin standard that allows to control the host's transport. A LV2
extension could do that, though. zita-dlp1 could do this via jack-transport.

Depends. Thread-safety and concurrency issues may rather produce strange
effects than segfault right away. It's mainly the EBUR128 meter (rapid
font rendering), Try adding two or more instances of the openGL variant.

It also depends on your graphics card. The plugins render directly to
graphic card memory. It works fine here with an old intel-945 and some
nvidia cards that I have tested: zero CPU. But Axel has various problems
with his Radeon on debian/stable. Also x11/xcb can make a huge
performance difference. -- Anyway, the concurrency issues
cairo/pixman/pango + x11/opengl have been fixed upstream and will soon
find their way int various distros if they have not yet done so.

Cheers!
