How to play audio from Application.persistentDataPath?

I want to play the audio I saved to the persistent data path but i can’t get it to work.

Here’s my code :

public class monyetRecord : MonoBehaviour {

	AudioSource monkeyAudio;

	public string url;
	public WWW audioFile;
	public AudioClip monkeyClip;

	void Awake()
	{

	}

	// Use this for initialization
	void Start () {
		monkeyAudio = GetComponent<AudioSource> ();

		url = "file://" + (Application.persistentDataPath);
		audioFile = new WWW (url + "/testAudio.wav");

		Debug.Log (url);
	}
	
	// Update is called once per frame
	void Update () {

	}

	//for recording narration
	public void RecordMonkeyVoice()
	{
		monkeyAudio.clip = Microphone.Start (null, true, 10, 44100);
	}
	
	public void StopRecord()
	{
		Microphone.End (null);
		SavWav.Save("testAudio", monkeyAudio.clip);
	}
	
	public void PlayMonkeyVoice()
	{
		if (!monkeyAudio.isPlaying) {
			monkeyAudio.clip = audioFile.GetAudioClip(false, false, AudioType.WAV);
			monkeyAudio.Play ();
			Debug.Log (audioFile.GetAudioClip (false, false));
		}
	}
}

I’ve been stuck at this problem for days. Please, any help will be appreciated

As of now this has worked for me, fullpath is the full path of the target file

private	IEnumerator LoadFile( string fullpath ) {

			print("LOADING CLIP "+fullpath);
		
			if ( !System.IO.File.Exists( fullpath )){
				print("DIDN'T EXIST: "+fullpath);
				yield break;
			}

			AudioClip temp = null;
			using (UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip( "file://" + fullpath , AudioType.WAV))
			{
				yield return www.SendWebRequest();				
				if (www.isError){
					Debug.Log(www.error);
				}else{
					temp = DownloadHandlerAudioClip.GetContent(www);
				}
			}			
			changeFunction.Invoke(temp);
		}
