Here are some general iTunes .mp3 conversion instructions to prevent file corruption.
Make sure that you are exporting your mix as an audio .aif file
at 44.1 and 16bit (CD standard)
(Higher resolutions also work 24 bit 48khz for example and on up!)
after you obtain this file , open it in itunes and set the itunes
Preferences-Advanced-Importing (selection button )
to mp3 192 -stereo (or higher to 320 stereo)
then press ok.
Preferences-Advanced-General show where the export file will be placed
and can be changed to a preferred location
Now, put the aif file in a new playlist (drag and drop)
and select/highlight the file in the playlist you wish to convert
and go to the Pull Down Menu ADVANCED and choose Convert to MP3
Your file will be in a user file folder from itunes. I hope you find this tutorial helpful.
