Real Waveform via FFT or other means?

How-To
1

Howdy, everybody.

It’s pretty easy to get the basic FFT effects working, but I’m having trouble getting waveform output that looks and moves like a proper waveform.

I’ve found the Waveform option in the FFT stuff, but when I select it, it doesn’t look much different to me than the EQ bands option. Turning down the spikiness seems to be a key to getting a view of the waveform, but when I turn it down all the way for that, the FFT just stops animating and shows me what COULD be a waveform, but if so, I couldn’t tell you where it’s coming from in the audio stream.

I’m doin’ somethin’ wrong, any suggestions on what I’m missing?

The FFT generator doesn’t really do this, but I have gotten it work before with some additional post fx and deformers! WaveformGenerator.dfx (6.2 KB)

In a pinch, I can just convert the waveform to a CSV and do it that way, but since Notch is a demoengine, I figured it really ought to be able to output the waveform without using a workaround since that’s a pretty common and basic demoscene effect.

Notch is not a demo engine, despite many demos having been made with it. It is so much, much more. :slight_smile:
