MicAudioCapture class

Class for capturing audio from microphone input devices.

This class allows you to capture audio from connected microphones, including built-in microphones, external USB microphones, and Bluetooth microphones. It requires microphone permissions.

Example:

final micCapture = MicAudioCapture(
  config: MicAudioConfig(
    sampleRate: 44100,
    channels: 1,
    gainBoost: 2.5,
  ),
);

// Check for available devices
final devices = await micCapture.getAvailableInputDevices();
print('Available microphones: ${devices.length}');

await micCapture.startCapture();

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

// Listen to status updates
micCapture.statusStream?.listen((status) {
  print('Mic active: ${status.isActive}, Device: ${status.deviceName}');
});

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

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