  // Pause the audio playback
  playerController.pause();

  // Set the playback speed. Accepts a double value (e.g., 1.0 for normal speed, 1.5 for 1.5x speed)
  playerController.setSpeed(1.5);

  // Seek to a specific position in the audio. The value should be between 0 and 1, where 0 represents the beginning of the audio and 1 represents the end.
  playerController.seekTo(0.2); // Seeks to 20% of the audio's total duration
