Visualising Audio waveforms

[adamt]

I've already posted this in the ghost town known as Smoke Area, so apologies if you've already seen it.....

does anyone know a way to visualise an audio input as a waveform within CFX/Action?

I have the Logik Matchbox sparks and the Genarts Sapphires but nothing looks obvious.

Perhaps there is a way to drive the amplitude of an axis node using volume levels? 

I know i can do this easily in After Effects but i would rather stay within Smoke.   

thanks

Hi Adam,

Not sure if this is what you're looking for, but you can generate keyframes based on audio analysis, from the Audio tab in the Channel Editor. See this Help topic for details: http://help.autodesk.com/view/FLAME/2018/ENU/?guid=GUID-A7EB45DE-4686-4968-B418-F0A41BD86B51

Hi Adam,

i created a shader just to play around with audio inside Flame

WIP: Audio Visualization - Matchbox Shader for Autodesk Flame / Flare / Smoke

its really simple and i can send the shader to you if you like it.

wow, that looks interesting Ivar...thank you. Its exactly the kind of effect i was looking for.

Yes please, i'd love to have a play with that shader!

Hi Adam,

see below for the shader.

You need 3 frequencies to animate the shader (Low, Mid, High)

you have to extract the animation curves from your audio file and then link them to the 3 shader values you extracted.

Have fun!

PS: Autodesk can you please fix the attachment ! I can't attach a GLSL File 😞

brilliant...look forward to playing with this!

thank you.
