I download a lot of live concerts which are mostly encoded in flac. Most concerts are over a 1 gig compressed. These files are fairly large so i download everything to my External Drive. Using xACT i then uncompress them to .wav, so they're even bigger. After that I then import them into itunes where i compress them to aac so i can listen to them on the ipod. Is there anyway that I can convert .wav to my default aac settings in itunes without having to import the .wav to itunes first. From my understanding, OS X defrags files under 20mb automatically. Since these files are a lot >20mb i dont want to fragment my hard drive by constantly importing and deleting. So basically i want to convert/compress on the external and then copy that much smaller .m4a file to itunes. Thanks for the help.
