spectograms with pd/Gem canbe done via the [pix_sig2pix~]-objects and
however, simple wave-forms cannot be displayed that easily (although it
a [pix_scope~] has been on my todo-list for years); i think there is a
similar object in pdp (or pidip) which you could then use with [pdp2gem].
and just recently somebody posted an example-patch for using the
openGL-wrapper things to display a sine-wave.
you could use this for arbitrary wave-forms too (and the clue is: it
wouldn't be a texture but a real 3D-structure; you could even make some
magic with the 3rd coordinate)
