Note frequency triggers specific colours – based on Alexander Rimmington
Velocity controls speed of movement of image and alpha
Note length controls length of image produced
I have already managed to get audio to trigger colours in accordance to particular note frequencies and amplitude.
To do this I have used the pitch~ object to analyse the audio and then used ‘If’ statements to specify the frequency bands and trigger specific colours.
The colours produced sometimes appear erratic (I assume because of note harmonics / tiny background noises).
I’ve tried a minimum amplitude but this means that sometimes colours are not produced for quieter notes. I have also tried reducing the output peak to one, however the display still appears erratic.
I’m having trouble with the creation of graphics in jitter. We have looked into jit.gl.sketch / render etc but can’t find a way of creating a line of a particular colour, from nothing, that appears to come towards you and lasts the length of the note played.
It would be wonderful if someone could help or advise me in any way.
I have a done a little bit of small playing around – somebody suggested jit.poke~ which is great fun and I use an fffb~ to split up the audio signal. There is a post called Hippie Patching that has some decent visuals in it. You might have a look.
