datamatrix is a Max/Jitter instrument that generates visuals by analysing the audio input.
UPDATED 24th March 2013 - FX box position can now be used to modulate FX - This is massively fun BTW! Download V3 below. I was teaching the other day and one of my students had this patch with lots of effects in it.
By using the pfft object in Max MSP I created simple video source of 50 by 50 pixels (50×50 matrix) so it can be used as a control for a LED matrix of the same dimensions. The process if very simple, by generating a subpatch with pfft, you can get the frequency bin that is being processed at the moment with fftin~, using the sound coming from the computer’s microphone. And from the same object you take the real and imaginary parts of the spectral analysis, with which you can get the amplitude and phase of such bin. fftinfo~ gives you information about the current subpatch used by pfft~.
A monster max patch(with dynamically allocated CPU) containing basic demonstrations of objects and techniques for 'sampling' in Max/MSP, organized for easy copy and pasting.
So… I want to use Jitter to create objects and distribute them in the visual virtual space, and I need to create matrices with as many locations as objects I want to display. These objects are to be assigned coordinates and dimensions.
Converts a matrix~ object into a mixer with volume and pan for each input.
Abstraction that creates a x/y speaker matrix to control your multispeaker setup's amplitudes.
