I'm a newbie in the forum!
These days I've encoded some mp3(320KB/s) to aac with iTunesEncode46.
After I finished encoding some mp3s,I found them incompatible with foobar to play.
But they can be played in itunes and Nero showtime!
What's the problem?
Can foobar played aac/mp4 encoded by iTunes?

Hi,dear Kl33per and Mike!Thanks for your help,you're right!

I just renamed the file with mp4 extension,and it can be played in foobar.
Though I've made myself a problem,I still have the following questions:
1.Can iTunesEncode46 output a file with aac extension?or iTunesEncode46 can only output a mp4 file indeed?
2.Normally,which type of file do iTunesEncode46 always output?(generally mp4?)
3.If I made my mistake again,could ipod play this aac which is mp4 instead?
4.I care about if the encoded files are compatible with my ipod.I visited the offical site of apple and knew that ipod could support protected AAC(M4A、 M4B、M4P).But I don't know if the file with AAC(MP4) extension is supported.Any experienced person could talk about something about this compatibility problem?
5.When I use iTunesEncode46 to encode a MP4,the default bitrate is 128KB/s.
How can I improve the encoding bitrate?
I've found you can modify one parameter in import setting of iTunes(edit-preference-import-setting-custom-192KB/s).
Is this the right way to improve the encoding bitrate?
6.I wonder if the iTunes support VBR encoding in AAC format.Since I haven't found the related setting in iTunes,I want to know something about VBR encoding in AAC format.
