Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Ask HN: How to get started with audio programming?
If you are on macOS, AudioKit is a nice simplified layer on top of CoreAudio and CoreMidi: https://github.com/AudioKit/AudioKit

Why Can’t You Design Noise in Frequency Space?
You can try the synthesizer and other audio code if you're using Linux.
Here's an earlier version of the synthesizer (licensed under AGPL3). The MIDI CCs for controlling different parameters are listed in the source code. You'd want to clone the repo, run through the installation instructions in the mb-sound repo, do a bundle update mb-sound, then run bundle exec bin/complex_synth.rb. https://github.com/mike-bourgeous/mb-surround/blob/3823de44a...
Here's the core sound repo (licensed under BSD) with some examples for getting started: https://github.com/mike-bourgeous/mb-sound
I don't plan on making the visualizations available, in part because the system is too convoluted and they probably only work in my specific environment.

Python, unlike C, has the mod operator always return a positive number
Ruby's % operator behaves the same way, for both integer and float values. A positive-only modulus function is useful for wrapping angles. This bit me a week or two ago when I was porting audio algorithms from Ruby to C, and had to implement a positive modulus function[0].

Learn more about the Fast Fourier Transform, animated in 3D [video]
Someone asked somewhat recently about visualizing analytic signals in 3D (https://news.ycombinator.com/item?id=28633829). This is my video, with 3D animation, summarizing the FFT and analytic signals, plus a review of digital sampling.
The submitted link is for a blog post about the video which includes a video transcript (repeated for reference: https://blog.mikebourgeous.com/2021/10/04/fast-fourier-trans...)
Here's a direct link to the video: https://www.youtube.com/watch?v=iyjIVSnrPSo
I've opened the Ruby code building blocks I use to produce these visualizations (which are not open): https://github.com/mike-bourgeous/mb-sound

Tenderjit – A JIT for Ruby Written in Ruby
Yeah, here's my main sound repo: https://github.com/mike-bourgeous/mb-sound
There's also an FFI wrapper for jackd: https://github.com/mike-bourgeous/mb-sound-jackffi
I'm certain there are still improvements that could be made to the APIs and to performance, so I'm not currently releasing these on rubygems.

Ask HN: How to get started with audio programming?
Edit: My goal is to make a mini-synth which takes input from the computer keyboard.
If you are a Ruby programmer, you could use this rubygem I wrote: https://github.com/mike-bourgeous/mb-sound
A video about using that gem to make a synthesizer: https://m.youtube.com/watch?v=aS43s6TWnIY&feature=youtu.be
Part of a long-running experiment of mine to make educational videos about sound, which I hope might help you on your audio programming journey: https://www.youtube.com/playlist?list=PLpRqC8LaADXnwve3e8gI2...
There have been recent posts to HN about the difficulty of reading key-up events from the terminal. I used MIDI and a separate MIDI keyboard app for my video demo.
