Software skills
There's a free book online called Think DSP that teaches you how to design and visualize filters in Python: https://greenteapress.com/wp/think-dsp/
- Think DSP: An Introduction to Digital Signal Processing in Python
- What programming environment do you recommend for implementing some DSP theory?
- What resource do you suggest to learn DSP from for embedded applications?

Fourier Series Visualisation with D3
https://greenteapress.com/wp/think-dsp/
It can be bought, but is available for free. Code is also available via GitHub. It uses Python and Jupyter.
"The premise of this book (and the other books in the Think X series) is that if you know how to program, you can use that skill to learn other things. I am writing this book because I think the conventional approach to digital signal processing is backward: most books (and the classes that use them) present the material bottom-up, starting with mathematical abstractions like phasors."

Elk Audio OS
Just found Elk Audio OS. Looks exciting, but I'm struggling to understand exactly what it is and how it might be useful. Anyone using it? https://elk.audio/

Real time audio processing in linux.
That might not matter too much for you - if not then you're set. But if it does, using small buffers is hard with Linux (and non-realtime OSes), since the kernel has other things to balance, so you can occasionally miss your deadlines and have audio glitches if the buffers are too small. These guys offer a linux distro that's been well tuned for audio processing, as well as an engine that makes it easy to drop in your effects algorithm without having to deal with hardware support and making that engine: https://elk.audio/

A curated list of Music DSP and audio programming resources
There's https://elk.audio/
Overall there are JUCE embedded support.
If you need more bare bones there are some DSP only resources. Not sure if I saw there the RtAudio which is also very minimal -

HW + OS for Loudspeaker Crossover
I’ve run JUCE apps on embedded linux, a Raspberry Pi running maybe Elk Audio or Patchbox OS might be a good bet
