dBpowerAMP can't open the .m4a files i have to convert them.

Re: dBpowerAMP can't open the .m4a files i have to convert them.

If they are true non-copy protected m4a files you could try playing them through dB Audio Player using the m4a codec. I'm sure Winamp and other players will have m4a capability if you have the appropriate codecs installed. However, my hunch is that the truest test of being able to play these files on your pc would be to try iTunes.

Re: dBpowerAMP can't open the .m4a files i have to convert them.

I downloaded Winamp and the mp4 plugin, and when I tried to play the files it said "Gain control not yet implemented." :vmad:

*sigh*

What does this mean?

Re: dBpowerAMP can't open the .m4a files i have to convert them.

It may mean that the plug-in type you used is not supported.
The question could be better answered by tech support at WinAmp. With some research I found the following threads over there that may relate to your question and/or help you find a solution:

Several on these mention using the in_mp4 plug-in. Is that what you used?
If not, I'd probably try that first.

I am using audiocoding's in_mp4 plugin. Is this the one you mean?

I downloaded a program that someone mentioned in one of those threads called Foobar2000 and it couldn't play the songs either. It brought up error messages saying "Unable to find correct sound track in the mp4 file." and "Error opening file for playback."

Have you tried iTunes?

Re: dBpowerAMP can't open the .m4a files i have to convert them.

I think Wayne is correct to suggest that you try iTunes.

I assume that these files are on a disk (cd-rom or cd-rw).
When you insert this disk in your pc, does your pc recognize the disk?
Can you open the disk on your pc to view (NOT to play) the contents?
What are the results?

These files are on my hard drive.

I haven't tried iTunes yet, but I will.

iTunes refuses to play the files.

I don't understand what could be wrong with them. They have been copied straight from my friend's computer onto my mp3 player and then onto my computer. They play perfectly on his computer. His computer is a Mac (not his choice) and mine is Windows XP if it means anything.

Did they play on your mp3 player?
Does your mp3 player support mp4/m4a/AAC and/or is it able to accurately support the transfers of files it cannot play?

I suspect that LtData's suspcions were correct, that these files may still have some degree of copy protection and that you will need to have your friend use a tool like jhymn to fully remove DRM (Digital Rights Management) restrictions to create a fully portable file.

Nope, they didn't. My mp3 player only supports mp3 and wma.

Re: dBpowerAMP can't open the .m4a files i have to convert them.

Can you tell me about your mp3 player?
Is it capable of copying and carrying data files?
Can it accept data files from a Mac?

Not knowing how Apple's DRM works but if it is anything like Window's version to play protected content you need to have a licence for each DRMed file. The licence also controls what can be done with a file. Maybe they can be shared but not converted.

Do you know if your friend, using iTunes, is able to convert the files to mp3/wma on his Apple machine?

Update: Check out this link which gives some details on how the DRM works in iTunes.

Nice link, Wayne!

Re: dBpowerAMP can't open the .m4a files i have to convert them.

When I try to play them in Windows Media Player with an m4a codec it says "Classfactory cannot supply requested class".

About my mp3 player, it plays mp3 and wma, and is capable of storing and carrying data files. That's all I know.
