How to execute to getEnergy()

[akkolad]

Hello,
Thanks again for your awesome work on this awesome project.
I've tried many ways, but I can't manage to execute the "getEnergy()" function.
Is this possible?

Hey @akkolad – I moved the audio reactivity code to the backend and thooought I documented using it in the readme?? but perhaps it's only documented in the demo : demos » audio » _audio_analysis

Anyways there's already an FFT object loaded, you can check out what's happening behind the scenes in p5live-audio.js – but essentially you just need to attach the getEnergy() to the exposed variable called fftRaw (fft is the already filtered array of values). Here's an example:

function setup() {
	createCanvas(windowWidth, windowHeight)
	setupAudio(true) // true makes all audio variables GLOBAL, otherwise use `a5.` in front of each var
}

function draw() {
	updateAudio()
	
	// print(fftRaw.getEnergy(1000)) // debug value
	
	clear()
	circle(width / 2, height / 2, fftRaw.getEnergy(1000))
}

Thank you so much, fftRaw was the key !
