     [Header("+++ Audio Source +++")]
     public AudioSource audio;

     [Header("+++ Fade Out Setting +++")]    
     public float fadeOutFactor = 0.08f;

     [Header("+++ Fade In Setting +++")]
     public float fadeInFactor = 0.08f;
 
     private bool fadeInOut = false;
 
     void Start()
     {
         //Switches the AudioSource volume to 0.0
         audio.volume = 0.0f;
         audio.playOnAwake = true;
     }
 
     void Update()
     {
         if (audio.volume <= 0.0f) { audio.Stop(); }
         if (audio.volume >= 1.0f) { audio.Play(); }
 
         if (fadeInOut == true)
         {
             if (audio.volume < 1.0f)
             {
                 audio.volume += fadeInFactor * Time.deltaTime;
