Audio Playback with Development Boards

Development boards of all kinds have now made a well established presence in the consumer market 2020.  Wether you’re fresh on the scene, or a battle hardened nerd, I’ll give you some reliable information.

Today I’m working on lightsaber R&D, and the first order of business regards audio processing on micro development boards.  I want my lightsaber to hum and play swing sounds at the same time, which poses a bit of a challenge for small computers.  Still, I know it can work from my experience with fancy development boards such as the proffieboard, or pjrc teensy boards.

I found a mention of something in a forum:
