Q: Why I convert my AAC to AC3?
A: My home theater can decode AC3 to 5.1 speaker. It cannot decode AAC directly.
Q: What is the advantage of this method?
A: This method use only 2 free tools: 1. Nero AAC decoder and 2. Aften
It don't require big .WAV file as intermediate (big file require time to write/read to/from Harddisk. It read AAC file and send wav stream to aften on the fly.
Heres how:
1. Download and put Nero AAC decoder and Aften to same folder of your choice.
2. Create batch file containing:
3. Create a short-cut to this batch file.Code:NeroAacDec -if %1 -of - | aften -readtoeof 1 - %1.ac3
4. Drag and drop your AAC file to this short-cut.
Another good thing about NeroAacDec is, it can demux AAC from .mp4 on the fly, so if you have movie.mp4, you can drag and drop it to the short-cut, it will produce movie.mp4.ac3 for you. There is no need to manually demux AAC out of movie.mp4 before use.
Note: I ran into a problem once, NeroAacDec connot decode my mp4, so I use YAMB to make make it good mp4. Now NeroAacDec and decode it.

Sorry to dig up an old topic, but I'm really tearing my hair out over this. Whenever I drag my aac files to the shortcut, the window opens, but nothing else happens, it just doesn't do anything. It does work as it should with mp4-files, so my batch file seems to be set up right. Did I misunderstand something?

aacDECdrop? It says it's FAAD2-based AAC/MP4 drag'n'drop frontend.
Thoughts?
