Almost useful and looks kinda funky. More-or-less compliant with BS
6840-10, BS 6840-17:1991 and IEC 268-18:1995.
Enjoy,

Steve,
The meters look good to me, but they're not moving yet... I think the
letters 'vu' could be a bit larger.
1) jackstart -R -d alsa -r 44100 -d Audigy &
2) meterbridge -t vu alsa_pcm:in_1 alsa_pcm:in_2 &
3) alsaplayer -o jack &
I think that alsa_pcm must be the wrong place in jack to attach the
meters, but I don't know how to determine where alsaplayer has attached
itself to jack? I guess I need that jack patch bay I've been reading
about... ;-)
Can I measure the output of alsaplayer, or the output of alsa itself?
How?
Thanks,
Mark

wow, nice.
it works for me.
i could even fire up all three at once, without problems:
meterbridge -t vu alsa_pcm:in_1 alsa_pcm:in_2 &
meterbridge -t ppm alsa_pcm:in_1 alsa_pcm:in_2 &
meterbridge -t dpm alsa_pcm:in_1 alsa_pcm:in_2 &
oh ye wonders of jack.
otoh, my system load is about 1.7, with both cpus peaking at 75%, with a
roughly estimated average of 50% (from a quick glance at xosview, fwiw).
oops, forget that. i was using ssh-tunneled xterms, and sshd accounts
for most of the load. the meterbridges do not exceed 10% each.
i'm a little puzzled by the vu meter, though. why do i have to set it to
-12 ?
if i do it looks ok, but why ? 12 db headroom for digital systems ?
out of curiosity, what would it show if i feed it maximum energy, i.e.
consecutive +/-max samples ?
the ppm is fun. i never saw one of those. still getting used to it.
i want a color-chooser dialog for the dpm. and a knob for contrast and
one for decay time.
(runs)
:-D
thanks for yet another useful piece of code...

Hi,
Meters look excellent. I installed and started them
but haven't got time to do any tests. The installation
on my Debian testing required some package upgrades
including libc6 and of course all the libSDL stuff.
All seems good.
Thanks much,
Ron
