What Does this Mean?

Hi, I wanted to know what this line of code means:

volume = "engineOn*camPos*1*(speed factor[0.5, 0.50])";)";

I'm guessing that :

engineOn = only when engine is active

camPos = Camera position

* = I think this means x (times)

The rest I don't understand :(

Does it mean the sounds volume will be played when the vehicle is at a certain speed?

My guess would be that the volume is determined by the angle the camera is shifted and the sound is toned down at halve the speed you move with incremental steps of 0.50 ? :)
