Hey again! I uploaded this code and got the distortion sound, albeit I noticed that there is a very strong hiss present in the audio signal. I saw somewhere on the Daisy Slack forums that this is a known issue, and probably generated by the hardware, but I couldn’t elaborate at this moment on the details.
Here’s a plot I made from [Audacity → Analyze → Plot Spectrum] of the first few seconds of noise/hiss to try and understand what the frequency of this thing is. (I’m just throwing darts in the dark, I have no idea what I’m looking at.)
Here is an [audio file download link] for my test of the distortion code for anyone interested in hearing the issue I described.
By the way, I am kind of blown away that it is possible to load a distortion pedal onto a tiny micro-controller! (Thx, Daisy!)
Great post, etchx, thanks for the effort you put into explaining stuff for newbies, I really appreciate it!
