Hi, Im wondering if this is doable. I want to texture map a waveform/spectrograph from an audio input on an object in gem. Or just display an audio waveform/spectrograph in the gem window. So i speak into a microphone and the resulting waveform is displayed in gem . Any ideas or suggestions? Thanks Nicky
spectograms with pd/Gem canbe done via the [pix_sig2pix~]-objects and apropriate [block~]-settings. 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)
