Why does  ```Audio::GetVolumeFromTo( int fromFreq, int toFreq )``` return ```0.0```?

I'm not very experienced in C lanaguages, but to me it look like ```Audio::GetVolumeFromTo( int fromFreq, int toFreq )``` always returns ```0.0```?

```
float Audio::GetVolumeFromTo( int fromFreq, int toFreq )
{
	return 0.0f;
}
```
