This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

The following files all contain material used for conversion. I was bored so I wrote this tiny program as a way to warm up before working on some PHP and Laravel stuff.
I used NodeJS. The code is provided below.
If you want the output, scroll to the last file at the bottom.
Tested on NodeJS 13.9.0!
Thanks for reading! :)
I recommend running Dmitry’s latest resonance testing branch and using the pulses method outlined below:

I would only go down this path if you're getting ghosting with really high speed prints. On the Annex Engineering K3 for example, no matter how perfect the graphs looked, I was still getting some ghosting. That prompted me to go down this path. I'm now able to print at 20-30k acceleration, 250-350mm/s, and 15scv with perfect quality that can usually only be seen at significantly slower speeds.
The default settings in Klipper have the damping ratio set to .1. This should be fine for most people with sane settings. I like to go for the insane.
