How Do You Find What Audio Files Are Used By A Route?

I have a number of Czech routes and the Ambient Audio is a bit Intrusive IMHO.

You are travelling at 160kph in a modern loco but you can hear Birds, Cows and other Audio which you would not in real life. How do I work out what Audio is used so I can amend it?
I tried TS Tools but that just tells you what is missing not what you have installed.

Thanks

Try the "Show Provider/Products used in selected route" button---it'll narrow the list down if nothing else.

 

Thanks Gary - doing that now
