Why is the apple m4a is so large?
I am trying to convert my flac files to apple's AAC format.
I am using ANYMP4 converter and dbPoweramp converters. The first generates raw AAC files; the latter generates m4a files. What surpised me most is the size difference on the output files (for the same quality: 256kbps).
Why is dbPoweramp bumpting up the file size (twice that of the outputs of the ANYMP4 converter)?
Re: Why is the apple m4a is so large?
The real size of a 256kbps file is easy to calculate, 256kbps = 32KB per second. If the track is 3 minutes long then:
60 * 3 * 32 = 5760KB or 5.7MB
if this other converter is half that size then it is not 256kbps...
