New Feature: Spectrum Analyzer

Open Pushpit07 opened this issue 3 years ago • 2 comments

I was working on a project and wanted to construct this- https://www.instructables.com/Raspberry-Pi-Spectrum-Analyzer-with-RGB-LED-Strip-/

I am using dancyPi and modified some code to achieve this but was unsuccessful. Can someone probably help in creating this ?

You can most likely do this with numpy. This project uses numpy to generate the LED visualizations, Here's the code for the scroll effects: https://github.com/naztronaut/dancyPi-audio-reactive-led/blob/master/python/visualization.py#L108

If you can figure out the sequence needed for the spectrum analyzer, you should be able to do something similar. I'm still learning and getting comfortable with numpy so I'm a little bit away from being able to do this efficiently. But I got myself a 8x8 WS2812b LED Panel for this purpose.

Hope this helps guide you in the right direction. Good luck! We can keep this issue open to see if anyone else has already worked on this.
