I made a visualizer for my track Time Perception in processing.

To create the bands I used a noisefield and used the current position of a particle to determine the new position. the index in the array of positions was used as the z-axis. So I basically created a noisefield particle animation but instead of drawing the points moving in time - i used "time" as the z-axis.

to create the 3D bands I simply activated hint(ENABLE_STROKE_PERSPECTIVE); in my setup() method

this visualizer written in ronin morphes between states of a lissajous figure in sync with the music.

I transition between the states by interpolating the state variables linear over a time periode that is in sync with 4 bars of the music.

I have been asked to share the code of the sound visualizer I wrote in processing about a year ago, so I decided to write a blogpost explaining what I did

The program has two main parts - the autocorrelation function that creates the wiggly line and a glsl filter for the lens-distortion effect.

For this animation I used an "Evaluate Sound"-Node to animate boxes placed on a circle

For this experiment I used the sound visualizer nodes form the animation nodes addon I have been asked for tutorials a lot lately and so I added a view screenshots and descriptions to explain how I achieved the effect.

as usual you can download the blend file here

please add a comment if you like this longer format posts or if you have suggestions for future posts.

the song I used for the animation is called "The Long Dawn - Part II" and can be found on soundcloud

To analyze the audio material you need a "Sound Bake" and a "Evaluate Sound" node. I also created a copy of the default cube for each bar I wanted in my animation using an "Object Instancer". The strenghts list and the object list are fed to a loop.

For this sound visualizer I animated the color of a diffuse material node using a driver and an empty node

the song I used is called "To be named" and can be found here

For this animation I baked a sound curve to the z-position of an emtpy. Then I used a cylindrical shape as a particle emitter that gets scaled by the empty and moved it along a curved path

I used the first 10 seconds of my song arp1 to test the visualizer

I made another blender animation by using the smoothing modifier to very extreme values. This time I animated them using "bake sound to F-Curve"

The sound-track was generated using hydrogen and a korg monotron
