Time Perception

Nikolaus Gradwohl2020-07-29T06:39:36+00:00

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

Time Perception

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

New Track - Time Perception

everything is flowing, existing structure is dissolving, time perception is completely off - days have passed but you still feel like your stuck at the beginning

Ronin experiment 21 - morphing lissajous states

Nikolaus Gradwohl2019-08-12T04:52:36+00:00

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.

ronin experiment 19 - Sonic Pi visualizer

Nikolaus Gradwohl2019-08-04T04:04:04+00:00

I created a short sonic pi session and wrote a visualizer for it in ronin. Sonic pi sends osc messages that change the amplitude, frequency and decay time of the sine wave based on the bass sound and triggers random colored circles when the pad sound is played

Phase Shift

Nikolaus Gradwohl2019-06-13T03:31:14+00:00

I made a video for my track "Phase Shift" in processing.

The song is two lines playing the same melody, but with different loop lengths - shifting in and out of phase

The animation was generated from a wild combination of trigonometric and noise functions generating 7200 curve vertices that are slowly changing over time

processing sound visualizer explained

Nikolaus Gradwohl2019-01-22T05:07:16+00:00

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.
