Is the clip playing right now (Read Only)?

Note: AudioSource.isPlaying will return false when AudioSource.Pause() is called. When you use AudioSource.Play() again back, it will return true.

	// When the audio component has stopped playing, play otherClip
	var otherClip : AudioClip;
	function Update (){
		if (!audio.isPlaying){
			audio.clip = otherClip;
			audio.Play();
		}
	}

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    public AudioClip otherClip;
    void Update() {
        if (!audio.isPlaying) {
            audio.clip = otherClip;
            audio.Play();
        }
    }
}

public class Example(MonoBehaviour):

	public otherClip as AudioClip

	def Update() as void:
		if not audio.isPlaying:
			audio.clip = otherClip
			audio.Play()
