Audio Using NAudio to create AudioClip in Unity, freezes 1-2 seconds while reading data

Hello, I was wondering if someone could assist with the issues I am having. I am currently using the below code in my Unity project to stream mp3 files from a directory. It works great however, it freezes while the file is read in and the float is filled. As this project is in VR the freezes are very jarring. How can I resolve it so that it can read in without the lockup? Do I try and put it on another thread?

When commenting out the below lines there are no hitches.

aud = new AudioFileReader(musicPath);

aud.Read(AudioData, 0, (int)aud.Length);

Code (CSharp):

1.  public void LoadSong(string musicPath){
2.  
3.     //Set title of song
4.     songTitle = Path.GetFileNameWithoutExtension(musicPath);
5.     if(songTitle != currentlyPlaying && songTitle !=
6. lastPlayedTitle){
7.         //Parse the file with NAudio
8.         aud = new AudioFileReader(musicPath);
9.  
10.         //Create an empty float to fill with song data
11.         AudioData = new float[aud.Length];
12.         //Read the file and fill the float
13.         aud.Read(AudioData, 0, (int)aud.Length);
14.  
15.         //Create a clip file the size needed to collect the sound data
16.         craftClip = AudioClip.Create(songTitle, (int)aud.Length, aud.WaveFormat.Channels, aud.WaveFormat.SampleRate, false);
17.         //Fill the file with the sound data
18.         craftClip.SetData(AudioData, 0);
19.  
20.         if(craftClip.isReadyToPlay){
21.             playMusic(craftClip, songTitle);
22.             aud.Dispose();
23.          }
24.  
25.         }
26.  
27.         else
28.         {
29.             playMusic(lastPlayedAudioFile, lastPlayedTitle);
30.         }
31.  
32. }

I have managed to improve the situation slightly by storing the last played song so that if the user selects the previous song that was played there is no delay.

Many thanks
