Up and down lines

Hello every one,
I’m very new to Dynamo but i’m capable of exploring tutorials to full fill my needs, so can you please suggest me a tutorial or a bunch of tutorials to do something similar below.
Thank you very much.

Not sure I have seen tutorials for this directly, but it is likely doable by analyzing audio files and pulling a value (vertical value) over time (horizontal value) and then generating the vertical lines from those points to a ‘maximum’ value, and doing so for a second layer of the audio to get the points which make the purple polyline that is lower in the image. Best to start with the Dynamo Primer as in any case you will have to know those basics.

I will go through the basics, thank you very much.
