encoding audio to AAC

[Tuffgong4]

Does anyone know of a program that I can use to encode audio to AAC. I have tried DBmusic converter with their codec but I keep getting errors. I can't figure out how to do more than one file at a time in iTunes and I'm just stumped. Freeware would be nice but I don't mind paying for some really good audio encoding.

If you're ripping a CD to AAC in iTunes, you just hit the Import button, and it rips them all without user-intervention.
If you want to convert to AAC from another format, just add the songs to the iTunes library, select all of them (use Shift and click), right click and select Convert to AAC. It'll convert each of them to AAC, again without user-intervention.

Is that what you meant by being able to do more than one file?
