Raspberry Pi Audio Visualiser

To play music at home, I use a Raspberry Pi and Shairport-sync to receive an Airplay stream and output via a pair of USB speakers.

I wanted to sample the audio stream, display an audio visualiser on the Display-o-Tron LCD display. Additionally I wanted to display the track info, which can be read from the metadata.

Using a bit of python magic, we can tie it all together...! Watch it all in action:

Shader "MaterialPropertyDrawer"
{
Properties
{
_MainTex("Texture", 2D) = "white" {}
 
[HideInInspector] _MainTex2("Hide Texture", 2D) = "white" {}

	using System;
	using UnityEngine;

	public static class Extensions_Math
	{

	// ...

	public static float VectorToRad(this Vector2 thisVec){
	return Mathf.Atan2(thisVec.y, thisVec.x);

	/// For this to work you need to copy these 2 files:
	/// "YOUR UNITY LOCATION"\Editor\Data\Mono\lib\mono\X.X\System.Drawing.dll
	/// "YOUR UNITY LOCATION"\Editor\Data\Mono\lib\mono\X.X\System.Windows.Forms.dll
	/// ..to a "Plugins" folder within your project
	///
	/// For this example to work, you need to have a (UI) Canvas object in your scene
	/// Put this script on any object
	///
	/// Tested on windows, not sure if it works on any other platform
	///

	-- 1. Paste this at the very bottom of your PICO-8
	-- cart
	-- 2. Hit return and select the menu item to save
	-- a slow render gif (it's all automatic!)
	-- 3. Tweet the gif with #PutAFlipInIt
	--
	-- Notes:
	--
	-- This relies on the max gif length being long
	-- enough. This can be set with the -gif_len
