Change Audio Clip at Runtime according Levels

 

Create a new Empty Object

name it DontDestroy because it persists as many levels loaded

attach the following script for not destroying

   1: void Awake () {

   2:     DontDestroyOnLoad(gameObject);

   3:     }

Then make a new script for audioClip changing

It will also attaches with the same Object as above.

   1:  

   2:     public AudioClip level2Music;

   3:  

   4:     private AudioSource source;

   5:     // Use this for initialization

   6:     void Awake ()

   7:     {

   8:         source = GetComponent<AudioSource>();

   9:     }

  10:     

  11:     // Update is called once per frame

  12:     void OnLevelWasLoaded(int level)

  13:     {

  14:         if (level==1)

  15:         {

  16:             source.clip = level2Music;

  17:             source.Play();

  18:         }

  19:     }

and that’s it Run in the editor and Enjoy :)
