Hello,

There are resources here including a sound library with examples:

> **[Welcome to Processing!](https://processing.org)**
>
> Processing is a flexible software sketchbook and a language for learning how to code. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology…

There are tools there to get you started and help you realize and unleash your creative potential.

And there are examples that come with the Processing IDE. Check the menus.

One example:

> [@Drawing a spectogram 2D (or 3D) from a recorded audio](https://discourse.processing.org/t/drawing-a-spectogram-2d-or-3d-from-a-recorded-audio/25708/20):

> Hello, I was able to add a few lines of code to the Processing sound library examples and do this: Upper left is the FFT plot of amplitude (y) vs frequency (x) with color added to amplitudes for each frequency. Lower left is time (y) vs frequency (x) with color added to amplitudes for each frequency. Right side is frequency (radius) vs time (angle) with a rotating sweep of the same data from lower left plot. Time was updated each frame. I am posting this to demonstrate that…

We are all volunteers here and may be busy with our lives.  
It is year end and that usually translates to a busy time for many.

Have fun!
