i made an audio file from quicktime, it's an mp4. I saved it in iTunes as an albm, playlist and song. Trying to transfer it to my iPhone so I can use it as an alarm sound

I don't have an i-device so I don't know if there is a difference between an alarm tone and a ringtone.

You cannot just use the AAC version for the ringtone/alarm tone. You have to change the file extension from m4a to m4r. Then you should be able to get it into iTunes. You will, however have to delete the m4a file if you make a copy of it. On my Windows computer, once I change the file extension, all I have to do is double-click on the file to get it to play and then add it automatically to the Tones folder to be used.
