Hi,
I've made a simple modification to the example in gr-paint in order to paint audible spectrum. You may see a video here: https://twitter.com/fedelarrocca/status/1250986553461047297?s=20 (the video is better than in the english version of the tweet).
It has the advantage that no SDR hardware is necessary. However, it uses linear scale on the frequency, contrary to what's usual in audio.
In any case, feel free to merge it or not. I've made a pull request just in case.
Thanks for this great OOT. I use it every year in class and in several other teaching environments.
Best
