Get Volume of AudioClip

How do I get the volume of the AudioClip (in C#)? NOTE: I do NOT mean the volume of the AudioSource.

I am trying to get an array of float values that could then simulate an audio graph like this:


Any help would be greatly appreciated!

 

Code (CSharp):

1. AudioClip audioClip = GetComponent<AudioClip>();
2. // the samples is an float array, -1.0f ~ 1.0f .
3. float[] samples = new float[audioClip.samples * audioClip.channels];
