Unable to import songs using NAudio

I am developing a VR Rhythm Game and am having major difficulty importing audio files from the filesystem. I am using NAudio for all my Audio calls. Here is the script which should handle it, it is run off a button press:

 public class songImport : MonoBehaviour {
     public void openFile()
     {
         OpenFileDialog open = new OpenFileDialog();
         open.Filter = "Audio File (*.wav;*.mp3)|*.wav;*.mp3;";
         if (open.ShowDialog() != DialogResult.OK) return;
 
         WWW www = null;
 
         if (Path.GetExtension(open.FileName).ToLower() == ".mp3")
         {
             var rawFileName = Path.GetFileNameWithoutExtension(Path.GetFileName(open.FileName));
             var newFileName = Path.Combine(UnityEngine.Application.streamingAssetsPath, rawFileName + ".wav");
             using (NAudio.Wave.Mp3FileReader mp3fr = new NAudio.Wave.Mp3FileReader(open.FileName))
             {
                 using (var stream = NAudio.Wave.WaveFormatConversionStream.CreatePcmStream(mp3fr))
                 {
                     try
                     {
                         NAudio.Wave.WaveFileWriter.CreateWaveFile(newFileName, stream);
                     }
                     catch(System.Exception e)
                     {
                         Debug.Log(e);
                     }
                 }
             }
             www = new WWW("file://"+newFileName);
         } 
 
        
 
         AudioClip clip = www.GetAudioClip();
 
         Music importedSong = new Music(clip, 10, "Jazz", Path.GetFileNameWithoutExtension(open.FileName), "Cameron Hadfield");
         MusicController.mc.addToList(importedSong);
 
         createMusicButtons.cmb.populateList();
     }
 }

Music is a custom class which takes in (AudioClip,BPM,Genre,Filename,Artist) I am unable to get any kind of audioclip it would appear because my call of samples on the clip returns null. Any help is very much so appreciated. Thank you in advance.
