Extract/Demux the audio from the mp4/m4v with mymp4boxgui.

I had to do something similar not long ago.

I'm fairly sure I used Video To Video Converter. After you open the aac audio, select m4a as the output format and change the audio encoding method to "Copy".

Try:

 ffmpeg -i filename.aac -acodec copy  -absf aac_adtstoasc filename.m4a
