Hey folks,
Starting work on an audio reactive animation and wanted to compute the difference between two sets of frequencyData. But in setting this up i noticed that for some weird reason when I compute the difference of two values from the frequencyData array and a past copy of the array, I get an occasional bug where the exported value of the variable flickers into an array!?
Here’s a simple test case, when I run this with some audio running through the sensor boards 3.5mm jack I get occasional flickers in the exported variable list in the ui and you can just about see the a variable gets turned into an array value for like a single frame.
// Sensor board variable
export var frequencyData = array(32)
export var energyAverage = 0
// --- Internal State ---
export var lastFrequencyData = array(32);
// =================================================================
// MAIN LOGIC LOOP
// =================================================================
export var a = 0;
export var last = 0;
export var value = 0;
export function beforeRender(delta) {
last = lastFrequencyData[2]
value = frequencyData[2]
a = value - last;
frequencyData.mapTo(lastFrequencyData, (value) => value);
}
// =================================================================
// VISUALIZATION
// =================================================================
export function render(index) {
var h = 1;
var s = 1;
var v = 1;
hsv(h, s, clamp(v, 0, 1));
}
