Apple introduced API that enables recording audio from other apps or the entire system in macOS 14.4, but it's poorly documented and there's no sample code available, so I decided to fix that: https://github.com/insidegui/AudioCap

@_inside has OBS not been capable of this for a long time?

@siguza Not sure about OBS, but this used to require a custom kernel extension or something, and it was a huge pain on Apple Silicon. This new API makes things easier.

@_inside apparently it's been supported since macOS 13: https://obsproject.com/kb/macos-desktop-audio-capture-guide

@siguza Interesting. No idea what they were using, but this API is new as of 14.4

@_inside a quick grep through the macOS SDK would suggest ScreenCaptureKit.framework?

@siguza @_inside You can record system audio with that, yes
