DecibelData class

Decibel data from audio capture.

This class represents a single decibel reading with its timestamp. Used by both microphone and system audio capture to provide volume level information.

Example:

// From stream
capture.decibelStream?.listen((data) {
  print('Decibel: ${data.decibel} dB');
  print('Time: ${DateTime.fromMillisecondsSinceEpoch((data.timestamp * 1000).toInt())}');
});

// Create manually
final data = DecibelData(
  decibel: -45.5,
  timestamp: DateTime.now().millisecondsSinceEpoch / 1000.0,
);

// Convert to/from map
final map = data.toMap();
final restored = DecibelData.fromMap(map);

Constructors
