SystemAudioCapture class

Class for capturing system audio (audio output from the device).

This class allows you to capture audio that is being played by the system, such as music, videos, or other applications. It requires screen recording permissions on macOS.

Example:

final systemCapture = SystemAudioCapture(
  config: SystemAudioConfig(
    sampleRate: 44100,
    channels: 2,
  ),
);

await systemCapture.startCapture();

// Listen to audio stream
systemCapture.audioStream?.listen((audioData) {
  // Process audio bytes
  print('Received ${audioData.length} bytes');
});

// Listen to decibel readings
systemCapture.decibelStream?.listen((data) {
  print('Decibel: ${data.decibel} dB');
});

// Stop when done
await systemCapture.stopCapture();
