Found this today when looking for something to turn short podcast clips into something more visual. Anyone have any other open source tools they like? I've heard of using ffmpeg (https://lukaprincic.si/development-log/ffmpeg-audio-visualiz...).

I had ended up using ffmpeg a few times for this (i think inspired by the link you gave there) because it's often easier to share video than just audio on mainstream social media

A few details of what worked for me and the output shown here:

But Astrofox looks much cooler and massively more sophisticated.

The key to all audio/music visualizations is the Fast Fourier Transform. Hook a FFT implementation to a graphics library and you are set.

You can use revoldiv.com. If you go to export and choose audiogram, it will convert the audio/video you uploaded to text and create an audiogram.
