Load MP3 files saved locally to AudioClip

Hi, i'm facing a new issue to load a mp3 file locally saved.
It was working untill now and it sudenly don't work anymore on ios platform.

✅If the audio file is not saved locally, i'm downloading from the url, convert it to audio clip and save it locally
❌If the audio file exist localy, trying to load it from local path

Code (CSharp):

1.  
2. string url = "https://myurl.com/"+filename+".mp3";
3. string strLocalPath = Application.persistentDataPath + "/"+filename+".mp3";
4. if(System.IO.File.Exists(strLocalPath)){
5.    ///This part is not working since few weeks. Trying to download the localy saved mp3 file and convert it to AudioClip
6.     WWW www = new WWW("file:///" +strLocalPath); //load the file
7.     yield return www;
8.     audioClip=www.GetAudioClip();//Get audio clip
9. }else{
10.    //This part is working, downloading the mp3 files from url and convert it to audioclip.
11.     using (UnityWebRequest uwr = UnityWebRequestMultimedia.GetAudioClip(url, AudioType.UNKNOWN))
12.     {
13.         yield return uwr.Send();
14.         if (uwr.isNetworkError){
15.                Debug.Log(uwr.error);
16.         } else {
17.              System.IO.File.WriteAllBytes (strLocalPath, uwr.downloadHandler.data); //save localy the audio file
18.              audioClip = DownloadHandlerAudioClip.GetContent(uwr);
19.          }
20. }
21.  

Error :
-[NSURLResponse allHeaderFields]: unrecognized selector sent to instance 0x283c83000
2020-03-22 10:40:04.834588+0700 pause[15301:4408918] Uncaught exception: NSInvalidArgumentException: -[NSURLResponse allHeaderFields]: unrecognized selector sent to instance 0x283c83000"

I also try to load the bytes array then convert it to an AudioClip doing :

Code (CSharp):

1. byte[] bytes = System.IO.File.ReadAllBytes(strLocalPath);
2. WAV wav = new WAV(bytes);
3.             Debug.Log("Wav loaded");
4.             AudioClip audioClip = AudioClip.Create("testSound", wav.SampleCount, 1,wav.Frequency, false, false);
5.             audioClip.SetData(wav.LeftChannel, 0);

But it doesn't seems to work properly, most of help i found online are working with WAV files. Not sure if that's correct for mp3 files...
Thanks!

 

You appear to be using the current UnityWebRequestMultimedia.GetAudioClip() API when downloading from a URL, but you're continuing to use the deprecated WWW.GetAudioClip() API when attempting to load a file for the local persistent data path. Try using UnityWebRequestMultimedia.GetAudioClip() there as well. For example, here's a script I wrote which does this exact thing:

Code (CSharp):

1.     IEnumerator LoadMusic(string songPath) {
2.         if(System.IO.File.Exists(songPath)) {
3.             using (var uwr = UnityWebRequestMultimedia.GetAudioClip("file://" + songPath, AudioType.AUDIOQUEUE))
4.             {
5.                 ((DownloadHandlerAudioClip)uwr.downloadHandler).streamAudio = true;
6.  
7.                 yield return uwr.SendWebRequest();
8.  
9.                 if (uwr.isNetworkError || uwr.isHttpError)
10.                 {
11.                     Debug.LogError(uwr.error);
12.                     yield break;
13.                 }
14.  
15.                 DownloadHandlerAudioClip dlHandler = (DownloadHandlerAudioClip)uwr.downloadHandler;
16.  
17.                 if (dlHandler.isDone)
18.                 {
19.                     AudioClip audioClip = dlHandler.audioClip;
20.  
21.                     if (audioClip != null)
22.                     {
23.                         _audioClip = DownloadHandlerAudioClip.GetContent(uwr);
24.  
25.                         Debug.Log("Playing song using Audio Source!");
26.                        
27.                     }
28.                     else
29.                     {
30.                         Debug.Log("Couldn't find a valid AudioClip :(");
31.                     }
32.                 }
33.                 else
34.                 {
35.                     Debug.Log("The download process is not completely finished.");
36.                 }
37.             }
38.         }
39.         else
40.         {
41.             Debug.Log("Unable to locate converted song file.");
42.         }
43.     }

 

That worked! Thanks, i tried with UnityWebRequestMultimedia but my script wasn't working properly like your.
Thanks @aihodge

 

No problem! Glad I could help.
