3D Spectrogram

[dwsubc]

Hi,
I have been using Audacity for a few days now and I am really impressed by it. Easy to use and the results are very impressive. Kudos to the developers!

Anyhoos, I created a bit of 3D artwork using the spectrogram view to help visualize a robin's song. Link and viewing instructions are here:-

I'd be interested to hear how you did that. Would you like to tell us?

Hi Steve,
It's a WebGL heightmap using the Babylon.js framework. I designed it so that people could generate their own versions just by taking a couple of Audacity screenshots. Let me knock out a quick tutorial and I will post the link here.
Would it be OK to link back here for any comments from the tutorial? (my blog gets swamped by spam)

On the Mac, you could use the free version of Sugaraudio's Oscarizor. The free version can only show one channel. Sufficient for most uses, as it is a fairly CPU intensive plugin.

Have just uploaded a tutorial to

Maybe someone could test it out with their own sound file.

Cool

If you want to keep it all open source, you could use Gimp rather than Paint.Net.
And for completeness, a link to the babylon.JS website: https://www.babylonjs.com/

@dwsubc, Are you able to build C++ applications (such as Audacity) from their source code? If you are, there's some new experimental scripting features in Audacity that may be of interest (if not, you'll have to wait until they are ready for release )

Good points. I can't believe I forgot to reference babylon.js. I have now.

My next step is to try a local build. I switched from C++ to C# a while ago but I could probably still get by. First task will be to add a hide toolbars menu item I then want to try directly converting the spectrogram data into HTML5 3D without the screenshot fudge above. Unless that is already covered by one of your experiments?

The "experimental" feature that I was thinking of is the new "scripting interface". To use this, the optional module "mod-script-pipe" is required, which must be built on the same day as the Audacity application. There are some potential security issues if running mod-script-pipe on a networked computer, but should be safe on a standalone or adequately firewalled machine. The scripting interface is already being used in-house for automating screen captures for the Audacity manual.
