m4a Files on Mac OS 9?

Is there a way to play .m4a files on Mac OS 9? I tried iTunes 2.0.4, QuickTime Pro 6.0.3, Audion and SoundApp. They all do not seem to support files with the extension .m4a.

You can convert them by burning it to a CD, and then re-import the songs (they'll be MP3).

Haven't tried it, but from The 6400 Zone

By changing the file type and creator of the AAC files encoded by iTunes 4 or downloaded from the iTunes Music Store from M4A/hook and M4P/hook respectively to MooV/TVOD or MPG4/TVOD, the songs can be played in OS 9. MPEG/TVOD files are recognized by QuickTime 6.0.3 and can be played in QuickTime or with a QuickTime based music player such as MPLAY. MooV/TVOD files can be played as above but are also recognized by iTunes 2.0.4.

What Protocol 7 says is right, you need to change the file type and creator to File type=MPG4, and creator=TVOD.
Probably you ll need some file utility like this one to do that job:

Thanks folks, I'll check this out. The .m4a file I have, though, was not recognized by File Exchange so that creator and file type seem to be TEXT and dosa. It's a message from a voice mail someone send me from his iPhone.

A voice mail message from an iPhone may not be m4a.

As Balrog says: ¨A voice mail message from an iPhone may not be m4a.¨

It is probably an .ogg
Anyway, before changing file type/creator, try to play it with this one:

Its a carbonized app (MacOS 9 & CarbonLib 1.6.1 for best results)

It's a m4a file. I erraneously assumed that it was from an iPhone voice mail. That was wrong. I asked the guy who sent me the file. He said he recorded it from his answering machine of his normal telephone with the recording device of his iPhone; then he made a m4a file.

Anyway, changing creator and file type worked!

However, I found a more elegant and faster method to do this than to use a creator changing applicaton:

I simply replaced the file extension .m4a with .mp4, and creator and file type automatically changed! I was able to play the file with QuickTime Pro 6.0.3! Isn't that great!

You win a prize if you can do it with a .m4b or .m4p extension Smile
