[QUOTE=deanimator;2537230]Hi and welcome
Format Factory can do this easily. Look for the “All to AAC” option on the left side, click, then add the file you want to convert.
It will easily convert almost anything to anything else!
[QUOTE=fredvdfox]hi, thanks for your reply
Format Factory doesn’t work, the problem is that i ripped the numbers fm an audio-cd fm a friend in Belgium. I am in Mexico for a longer time now and cannot open the numbers without a license?? because while making a copy the file has been saved
