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:
https://github.com/TMRh20/TMRpcm – Arduino library for asynchronous playback of PCM/WAV files direct from SD card.
