Just ran across this. I assume this is the audio layer off Mpeg4 video, like
MP3 was the audio layer off MPEG1.

Anybody know if it's any good? I'm doing some googling... but getting opinions
that actually stand true when it somes to the quality of compressed audio
can be difficult.

Cheers,
Kim.

It's also known as AAC - or the format that Apple uses for iTunes if
you so choose.

I ripped my entire cd collection into m4a for casual listening -
sounds pretty good, and lower-bitrate m4a (aac) sounds as good as
higher-bitrate mp3, and take less space.

I only use iTunes for casual listening, and for filling myPod. If I
want to do critical listening, I use the original cd in a real cd
player. So aac serves it's purpose.
