Loopback not working. Loopback REALLY not working

so tl;dr windows audio loopback is driver dependent and basically useless. all the work I’ve done, while not completely a waste, is a lot less progress than I would have hoped.

fixed up my old visualizer demo though
that’s cool

Loopback working! (for now…)

I can definitally see some flaws in it, but it’s working!
It’s actually capturing audio!
next step is to make a very basic visualizer to actually see what it’s capturing
Stay tuned!

Prototype: 33% complete

Loopback pain very sad

First thing I’m working on is the audio loopback,
grabbing the sound going to the speakers.
Since I’m doing this in rust, I’m using the cpal library, which is kinda annoying ngl
It seems to support most os so hopefully I won’t have to deal with that myself.
I think I have a working setup, but we’ll have to see

To-do:

  • [] Getting system audio
  • [] analyzing the audio in real time
  • [] generating the pretty picture
  • [] displaying to the background
  • [] add customization (optional)

Devlog the fourth: IT MOVES

You heard it right folks: I’ve finally got something moving on screen!
didn’t capture it though cuz I didn’t feel like setting up screen capture rn
despite the progress however, C just doesn’t feel right for this project. I could get it to work, but it would be hard to expand, which is the opposite of this project.

the road ahead (realized “roadmap ahead” didn’t make sense”)

  • this repository’s getting rusty ;)

Devlog the third: IT’S ALIVE

I mostly finished up the cmake config! it was actually a bit easier than I expected (although I did have to ask gemini a few questions)
I don’t think I really understand it fully though, so I’ll keep tinkering with it while I move on to the next things
speaking of which…

the roadmap ahead:

  • tinker with cmake a bit more
  • drawing something on screen!
  • prettying up the code (header files and what not)
  • MOVEMENT crazy stuff, I know.

Devlog the second: Ok quick detour, I promise it’ll be fast

so I’ve officially decided on using C for this project (for now…)
I technically know how to write C, but I don’t know how to do so effectively, if you know what I mean.
also I need to link raylib to get the program to compile

So, why not use this as an excuse to learn all about compilers, cmake, .h files, libraries, linking, gcc, sublime text build systems,

seems like a lot, is a lot

the roadmap ahead:

  • setup cmake so compiling with raylib isn’t annoying
  • setup sublime text so running cmake isn’t annoying
  • compile with raylib!

Devlog the first: the beggi the beginni the beginging the

just set up the github, and made some rudimentary structs
I won’t lie my C skills are Rusty af

the roadmap ahead:

  • drawing stuff on screen (raylib my beloved)
  • making a circle drop (force -> velo -> pos)
  • more circles

expect this list to shift as I move ahead on this journey ;)

Firmware time

Omg the firmware is so much harder than I hoped

I have no idea what I’m doing, I’m already tired and stressed, and the resources haven’t helped much so far.
This feels like trying to piece together a program from someone else’s random programming language. At least it has ok documentation (for what I’m trying to do), but it’s just
so
confusing
omg
I’m like entering crash-out territory on this project

Need help!

Been working on the details of the case. I’m really pulling out all of the stops (that I am aware of) for this project. Here’s the rough sketch!

Man I wish I made the case together with the pcb. having to go back and edit the pcb because something didn’t turn out quite right on the case is such a pain

Lapse ate 2hrs of work today, turns out I’m not supposed to pause the recording and then turn the computer off or else the recording corrupts silently. if anyone knows where I can find the 3d models to the components, please tell me!
