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

- Raspberry Pi 4 based synth - questions about external sound card.

Timing animation with music
You should also check out AudioKit. The latest release should have an audio engine completely rewritten purely with Swift iirc.

Xcode 13: "Add packages" doesn't do anything
I' just installed Xcode 13 and try to run a playground that uses a package (https://github.com/AudioKit/AudioKit). To add it I'm supposd to select "File -> Add Packages...", but when I do this absolutely nothing happens. No window appears, no error message, just nothing. What could be the reason for this?

I spent the xmas break learning how to make my own plugins
It seems to be the industry standard at least. I have played around with iPlug2 and AudioKit a little bit but not enough to really form an opinion. (iPlug2 is described by the authors as "not production ready" and AudioKit is mac / ios only)

How to make something like audacity in IOS?
You’re up for a lot of work, but I would start with AudioKit which is an abstraction over AVFoundation.

Hey, I have this two way slider, and I am trying to make it change the end and start points of recordings, i have already coded the recording part with AVfoundation
Maybe check out AudioKit, it’s great for audio stuff.

I want to make a MIDI instrument. Should I learn Swift or would something like HTML5 be easier?
There are open sources synthesizers projects for iOS in swift. I would recommend giving it a look and see if it fits your needs. https://github.com/AudioKit/AudioKit

Best way to consume CMake based C lib in Swift for iOs/desktop
I can’t help with that, but I would suggest looking at AudioKit. Even if it doesn’t help you replace that dependency, it might give you pointers for doing it yourself.
