  void initialize(double sampleRate, int maxBlockSize) {
    // Initialize your audio processing
  }

  @override
  void processStereo(List<double> inputL, List<double> inputR,
                    List<double> outputL, List<double> outputR) {
    // Your audio processing logic here
    for (int i = 0; i < inputL.length; i++) {
      outputL[i] = inputL[i]; // Pass through for now
      outputR[i] = inputR[i];
    }
  }
