Taking inspiration from this topic: http://cycling74.com/forums/topic.php?id=36373
and combining with the "SoundLump" jitter recipe, I obtained this patch, using jit.gl.mesh to visualize the lines generated with jit.catch and a "masking" texture captured from camera:
the only issues regards lines color, which in the "non-masked" version of the patch are white, while in the above patch they appear black.
Am I missing something? Maybe inverting planes?
Here is the SoundLines patch without masking.
