How to get a volume of a group?

Hi, i want to make a inverted connection from volume of Explosion's group to Master's pitch (don't ask me why )
for example:
vol = -6 pitch= 25
vol = -60 pitch = 100

I exposed master's pitch, everything is changing properly, but i found no way to get a volume of a group.

How to do it?

 

Is it possible? I know the API is severely lacking (I wasn't able to tell whether a Group was muted or not for example).

 

You could expose the Volume of that group, the volume within the Attenuation, and then just do
GetFloat(string name, out float value);
to get the volume

example

Code (CSharp):

1. float masterVolume=0;
2. audioMixer.GetFloat("MasterMixerVolume", out masterVolume);

I hope that helps.
