Software :: Transferring Music Downloads To ITunes?

I have been trying to download my mini-discs to my MacBookPro.

I have had little success with Garage Band as I cannot really get the hang of such a complex program.

I have had some success using "Audacity". I do manage to get the minidiscs onto the computer. But that is where the problems start.

I obviously want the music in iTunes, but cannot manage to do this. I can get the downloads into any progam except iTunes which just refuses to accept them. I can store them in Music but this is not very satisfactory as it is longwinded to retrieve them and they cannot be downloaded to CDs. The files are in aiff format Which takes up over a gigabyte of space for a 1 hour minidisc. These can be converted to mpeg in iTunes but not in any other program.

I have previously been able to download aiff format music but now find I cannot get them into iTunes.
