Gapless with M4A files?

(1/1)

michael.conner:
I was pleased to see the recent updates to AAC support on Rockbox -- playback seems very stable.  With iTunes-encoded AAC, though, I'm not getting gapless playback -- very small (100ms perhaps?) gap between tracks. (Haven't checked Nero-encoded AAC files.)

Is this likely an encoder issue?  Ironically enough, they play back completely gaplessly in the Apple firmware.

Llorean:
I thought that AAC wasn't a natively gapless format. Somewhere I read that iTunes actually stores additional gapless information (similar to LAME) but keeps it in the iTunes DB.

Remember, the above is all *second hand* information, so should not be taken as something I necessarily believe, just the only say I've heard on the issue so far. I'm slightly distrustful of it.

AAC isn't natively gapless. Nero has supported gapless encoding for some time, by adding metadata. Itunes now does too, but in a different way. Afaik, it is stored in the file.
