I read about this programe prior to purchasing it on line.I was iterested in it because it boasted of so many special efects including audio dubing witch i was mostley interested in.Alas i can not find any.I can change the tone of a cd 50 direrent ways why do i want that.I phones customer service and they said yes and advised me to contact tech suport,at the cost of £10 i did this and he assured me it had to. Is there any dubing audio sounds efects?Thank you.David
