Dear All,

Right now im working on a project, where i want to use an audiosignal to trigger a video and i have to admit, that even though i am somewhat new to processing i find myself building a cathedral. So: HELP! PLEASE!

A repeating Audiosignal triggers several functions:
a) It should save a frame (A) of an attached camera.
b) Everytime a new frame (B) is saved the old one should be drawn. ("Visible on the screen")
      Whenever Frame A is drawn, Frame B becomes Frame A and a new Frame B is saved.
c) In between those two frames should be a blackscreen. ("Which should also be triggered by a second audiosignal {best case scenario} or by time")

Sketch:
FrameA > FrameB > Blackscreen > FrameA > Blackscreen > FrameB > Blackscreen > FrameA > Blackscreen > …

I managed to get the Blackscreen working, but still a big Questionmark remains floating above my head, when it comes to Frame A+B.

I hope someone can spare the time to look into my mess :)

Kind regards,
