Give a mini example of you data and HOW you want it to be 3Dā¦
In principle objects in Blender are (x,y,z) points where three or four (neighbouring points) are connected by a āfaceā (VISIBLE)
Point a alone can be made visible too by a āhaloā material ā¦
Edit:
Or do want to show a frequency as a curve (time-dependant value?) THAT would be easy I think.
an exmaple of the audio data and give an idea how to intend to convert form audio data to an object would be nice
to see what is involved here !
iām having problem with the relationship between sound data and object !
i mean are you talking ampltude or frequency components of the audio signal here or something else?
and the 3D object that i am trying to build looks like this:
pretty much is amplitude and frequency i am dealing with,
the method i am doing to extract the data is by exporting a .wav file to ASCII text data from cool edit, so i donāt know if it is the best way, but if you can suggest a better way to extract the data please feel free!
Hi, you can work inside Blender: use ābake sound to f-curvesā operator to animate some property, itās under spacebar menu in f-curve editor. Then try this script in radius mode to get the 3d bezier from the baked f-curveā¦ or go the other way, and generate some mesh from your numbers, you will need to write some simple script
You may find this script usefulā¦ I noticed this post and made some quick fixes to make it an addon to make it easier to use.
It uses speaker objects and the bake sound to fcurve modifiers to make a one click spectrum.
To get the multichannel representation like you have in the text file you would need to split the original file into two mono tracks L & R or make it mono using something like audacity.
To make the object that is in your post Iād write a script that uses the baked fcurves to edit the control points of a curve object from the sound fcurves. Seeing itās a waveform its a chunk of timeā¦ the waveform curve then be used as a taper on another curve. Shouldnāt be too difficult to script if you need a hand give me a hoy as it would be a good addition to my addon.
I am also having the same problem that I want to convert sound into a 3d curve. I downloaded the above blend file and from the looks of it that is jst what I need.
But I canāt seam to make it work for me. I dont know what I am doing wrong.
I copy/pasted the script into my text editor,
I created a cube and baked a sound to it ( so that it moves to the beat),
and then I pres ārun scriptā and nothing happens
can someone give me a more detailed instructions on what I should do what I should press.
Lollito just checked it and seems to work fineā¦
script is a bit different from the one on blend -guess I updated it at some time- settings are under F6 dialog
check your object -with some baked fcurves- is selected
script is pretty simple, should workā¦ pm me the file if you want
recently seen something like this in stackexchange also
Hi again, and thanks for helping.
I have to create a bake action before unbake. But i donāt see any unbaked 3D curve in viewport and outliner.
May i miss one step.
Here the blend, i packed all. Tell me if you donāt have the sound. http://www.pasteall.org/blend/36174
it seems you baked to shapekeys and the script does not read shapekeysā¦
just bake to a transformation channel, like z location; will try to expand script later http://www.pasteall.org/blend/36175
