Introduces system audio capture as an alternative to microphone input using macOS ScreenCaptureKit. Includes a Swift helper binary that captures and streams 16kHz mono float32 PCM, an AudioSource abstraction layer, and full UI integration with an audio source selector dropdown.

There was a problem hiding this comment.
Screen audio helper should not live in whisper_cpp folder

@adamdexter Checked the implementation and a thing that is immediately missing is some build instructions. Main app is built via Makefile See if you can add build commands for screen_capture helper there as well. Feature is useful, so I can look into the missing parts myself as well, at some later free moment. |
