dBPowerAMP Music Converter (even the new MP3-crippled versions, I'm sure) will decode from MP4 - that includes M4A - and AAC* files to Wave, as long as you've installed the proper plugin from their website.
*provided the AAC file has ADTS headers, that is. Another note: I think it also only works when the MP4 file contains AAC, not MP3.
It's possible to extract AAC streams from MOV (or MP4) files with MP4Box (or YAMB, if you prefer - it's just an MP4Box frontend, makes things simpler - just remember to get the 1.6 version of YAMB, I feel the newer one is actually less intuitive).
