A configurable realtimedisplay can be built using ams (alsa modular
synth). Ams hast a oscilloscope plugin that displays whatever gets
through as continous wavegraph. You have to route your input into ams
(can be made parallel to your regular routing so no processing is being
add to the actually recorded signal).Maybe this can help.
I made a patch for ams, that provides some basic FX plus the
oscilloscope, (if you dont want/need the FX you can simply remove the
respective plugins and keep the oscilloscope only). Get it here:

the patch is named basic-fx.ams, you need the usual suspect
LADSPA-Plugincollections plus ams of course, to run it.
The tuning-app fmit also displays a realtime-wav-view, yet this apeares
somewhat too clumsy for that job ;-)

best regards
