PIDs for can be very fun. And essentially its just 5 or so lines of code, which is something I wish they told us in uni (instead, it was mostly theory, as in the meme). I recently built a kiln which goes to 1000-something °C with a PID controller and I just set the parameters by vibes, not even some formal method. And it just works. So here is my resource: The (bit messy) controller code for my oven The code is obviously a bit more than those few lines, but I just wanted to say that the implementation is very simple, which I would have liked to know when I started out with this.

Edit: just found a bug after looking at the code again haha, so thank you :D

Plus, your source files would also have to actually be in that format. As an example, Spotify apparently supports up to 24-bit/44.1 kHz FLAC only

The observation is that most USB-C to 3.5mm (“aux jack”) audio dongles are supporting high quality audio but only support the USB Full Speed (FS) data rate which is not enough for the high quality audio. This causes problems.
