Load ogg file into audioclip

Question

Hi, I created a little audio editor i need as tool for a game, were other people are able to edit custom audio files. So I can't load them through resources.load. I at least came up wir using the www class. but the problem is, that I need to use Coroutines to make it work - i can't get around it. Here is my code so far:

     public static AudioClip GetAudioClip(string mp3FileName) {
         string s = MP3_FILENAME_UMLAUT_CODE_CHAR.ToString();
         mp3FileName = mp3FileName.Replace("ö", "o" + s).Replace("Ö", "O" + s).Replace("ü", "u" + s).Replace("Ü", "U" + s).Replace("ä", "a" + s).Replace("Ä", "A" + s).Replace("ß", "s" + s).Replace(" ", "_");
         mp3FileName = MP3_RESOURCES_SUB_DIR + mp3FileName;
 
         AudioClip mp3Clip;
 
         yield return StartCoroutine(loadAudioFile("File:/" + mp3FileName + MP3_FILE_EXTENSION, value => mp3Clip = value));
     }
     IEnumerator loadAudioFile(string url, System.Action<AudioClip> result)
     {
         WWW www = new WWW(url);
         float elapsedTime = 0.0f;
         
         while (!www.isDone)
         {
             elapsedTime += Time.deltaTime;
             if (elapsedTime >= 10.0f) break;
             yield return null;
         }
         
         if (!www.isDone || !string.IsNullOrEmpty(www.error))
         {
             Debug.LogError("Load Failed");
             result(null);    // Pass null result.
             yield break;
         }
         
         result(www.audioClip); // Pass retrieved result.
     }

Problem is obviously, that GetAudiClip must be of type IEnumerator, but then I can't return the value to the calling function. Is there any way around this?

 private IEnumerator LoadAudio(string audioName, int track_id, float start_time)
     {
         
 
         using (UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(
                                         musicPath.Replace("#","%23") + 
                                         
                                         audioName, AudioType.OGGVORBIS))
         {
             
             var synRes = www.SendWebRequest();
             yield return synRes;
 
             if (www.isNetworkError)
             {
                 Debug.Log(www.error);
             }
             else
             {
                 stream_music = DownloadHandlerAudioClip.GetContent(www);
                 musicSource.clip = stream_music;
                 musicSource.time = start_time;
                 current_track_num = track_id;
                 current_track = GetCurrentTrack();
                 musicSource.Play();
             }
         }
 
     }
