I would like to add some inspiration from projects on GitHub with pictures that do spectrum analysis with C/C++ code: # [bradleybauer/music_visualizer](https://github.com/bradleybauer/music_visualizer)   # [aiXander/Realtime_PyAudio_FFT](https://github.com/aiXander/Realtime_PyAudio_FFT)  # [kojigardiner/audiobox](https://github.com/kojigardiner/audiobox) ...
