Improving jit.poke?

April 24, 2009 | 10:14 am

Hi all,
Ive been making my first VJ app making use of jit.poke but feel I have to now begin to improve upon its out of date appearence.

As you may know jit.poke is used to feed audio through it to create a spectrogram or whatever, but im looking to create something similar just of better quality.

At the moment jit.poke comes out very grainy and bitty can anyone give any advise on how to improve its appearence and smooth it out. Maybe there is a another way of doing the same thing with a custom patch without jit.poke? If you have any advise and can point me in the right direction let me know?

For example how could I make the waveform line that is traced in the help file thicker or add a glow to the traced line.

Thank You.

I guess you are talking about jit.poke~.
This object just writes values in a jit.matrix.
If it’s "coming out very grainy and bitty", it is because of the rest of your patch, not because jit.poke~ must be improved.
I suggest you isolate your problem in a simple patch, and post it here, so more users can understand what you’re talking about and help you.
You could of course "improve" on the help file in a variety of ways, using different jitter filters before display, or going to OpenGL world.
J-F.
