 For the CircuitPython Parsec today, I want to talk about playing a wave file, an audio wave file inside of CircuitPython on a microcontroller. The key here is that we have this library called AudioCore, and from there we can import the wave file. And once we have that, we can go ahead and open up a wave file that's on disk. So you can see here I've got four wave files loaded onto my little cutie pie sitting right there. And then I have a little macro keyboard, actually that's that one by four plugged in there, so I can pick some different samples. So I open those wave files, I assign them to the wave file object, and then I am actually going to do something fun here. I'm going to play them back at different sample rates, which will speed up and slow down the samples. So next thing I'm doing is setting up I squared C so that I can use my little one by four Neo key here. And then playing back wave files once you have them opened is as easy as audio.play and then the name of the wave object that you created. So in this case I have audio.play, wave zero, wave one, wave two, and wave three. Now when I click on these keys, you're going to hear. That is how easy it is to play back a wave file inside of CircuitPython, and that is your CircuitPython parsec.
