What is the difference between an .aac file and an .m4a file? If I just change the file extension of an audio file recorded and then converted into "AAC" between .aac/.m4a it drastically affects how the file is treated.

AAC: Plays in a web browser, not on the iPad M4A: Plays on the iPad, not on a web browser.

Is there a real conversion between the two formats?
