No problem, I am giving you two links one will open Catooh with Soundpool collection click on the desired one and then you could see the license price. In the 2nd link for reference I have opened the 2015 Premium collection where you can see Audio pro license fees.

If you do not got Catooh account before you buy you need one to make. Do not buy unless you are satisfied. Use the Catooh contact for any kind of help if needed.
