Do you mean 44,100 Hz?  

Could you screen shot the file properties dialog box in foobar2000 or some similar app that can give MP4 stream info?

Lear:
I encoded two files using iTunes 7.6 set to 320 kbps AAC, and they play fine on my Sansa e200 (though the boost ratio is high), so I'd expect an iPod Video to be able to handle it too (at least after buffering is complete). However, the high pitch suggest Rockbox is not parsing the files correctly. If you can send me a (preferably small) test file, I'll take a look at it.

Yes, I mean 44.1 kHz.

Well, I guess looking at foobar2000 shows I didn't use iTunes to rip this perticular CD. It's only 192kbps too. But this is one of the files I am having troubles with:


I have sent a link for that file for Lear, so hopefully he can see what the problem is.

trudslev:
Well, apparently it was a brain fart on my behalf (as expected by me). The file is a HE-AAC file, and not created by iTunes. I'll re rip it a proper format.

senab:
192kbits HE-AAC, are you mad? You shouldn't really use HE-AAC for anything over 80kbits.
