HIFI index out of bounds error

Trying to use this library to implement the HiFiVisualizer. Everything works well with the CirlcleLineVisiualizer. Simply switching to HiFi causes an index out of bounds error. Code below..
```

```
`private HiFiVisualizer visualizer;`
`visualizer = findViewById(R.id.blast);`

MediaPlayer is in a background service and passes sessionId to MainActivity through Interface like so

```
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
if (MI != null) MI.setSession(mp.getAudioSessionId());
if (!mute) {
gainFocus();
mp.setVolume(volumeA, volumeA);
}
mp.start();
updateDisplay();
}
});
```
```
@Override
public void setSession(int id) {
if (id != -1) visualizer.setAudioSessionId(id);
}
```
Like I said before, everything works great when using CircleLine or Blast. Changing the XML from CirlcleLine to HiFi along with the global variable in the MainActivity to match compliles fine, runs, and causes the following crash.

Am I missing something here? The audio format is M4A (MPEG_4_Audio)
