I've got some raw 5.1 ac3 files (and also some 2.0 ac3) that I would like to burn onto a cd so that my cd/dvd player will output the ac3 music stream off the cd to my DD preamp. is this rocket science? or is their a pretty simple way to burn raw ac3 files onto a cd-r? link to a guide if already posted. thx
I just did this today for the first time & it worked like a charm. So I wrote up a little Guide as to how I did it. It has to do with the ripping of music from a DVD & then converting to a OGG, MP3, or Wavwe file. So you'll just want to do the second part & convert to a wave file then burn away.
This is how I ripped music from a DVD of Jimi Hendrix. I first used this guide for using DVD Decrypter that I got somewhere but can't recall, so I can't give proper credit to whomever wrote it. (Sorry!!)
1) First make sure that DVD Decrypter is in IFO Mode!
2) Click on the main Concert file under the input tab
At this point you can choose to rip all of it or just one scene (or song).
3) After sellecting the files you want to rip, click on the Stream Proccessing tab.
4) Enable Stream Proccessing
5) Check the Audio stream box only!
If there are multiple audio streams choose the one that only has two channels.
6) Now, highlight the checked audio stream and choose to Demux it. It's important that you highlight along with putting a checkmark.
Now your ready to rip!
7) Rip the DVD (audio stream) to your hard drive by clicking on the DVD to hard-drive icon.
That should create an AC3 file. Once you have the AC3 file you need to convert it to wave or mp3. This can be accomplished with a program called HeadAC3he. To do this follow this procedure.
1) Download all of the following & extract to the same folder. I'll give you the link at the end.
a) HeadAC3he
b) Azid DLL
c) Libmmd DLL
The following one's seem to be different for different Processers. So scroll down the page for the proper one.
d) SSRC DLL
e) Lame DLL (for making MP3's)
f) Vorbis DLL (for making OGG files)
Personally, I prefer to just creat a wave file & use dbPoweramp to create my MP3's.
2) Open HeadAC3he
3) Click on "Source File" & navigate to the source & open it.
4) Click on "Destination File" & navigate to wherever you wish to save the wave file.
5) About 1/3 of the way down, click on "Destination Format". This is where you opt for OGG, MP3, or WAV.
6) About 2/3's of the way down, make certain you put a checkmark in the "Resample to:" box & have it set to 44.1 kHz.
7) Click the start button & that should be it!!
Quote: Once you have the AC3 file you need to convert it to wave or mp3.
I guess, I wasn't clear. I want an AC3 (dd-5.1) cd if possible, so that the AC3 files on the cd will 5.1 audio only. I don't have any problems converting the VOB or AC3 files to wave with besweet.
BeSure is a front-end for BeSweet and SurCode CD Pro DTS. It allows you to create DTS or Dolby Digital audio CDs. It uses BeSweet to decode the AC3 (including SSRC downsampling) and then SurCode CD Pro DTS to create DTS, or the freeware ac3enc to create Dolby Digital WAV files which you can then burn onto an audio CD using your favorite CD burning application.
BeSure & BeSweet are reverse engineered items that will not reliably produce a valid Dolby Digital (ac3) file to specs.
It may work most of the time, but the resulting stream is not Dolby compliant.
The way to do what you are trying to do is indeed to create a Dolby Digital WAV file, and this will encode the stream to what looks like a 16/44.1 stereo WAV file.
This will allow it to be burned to an audio CD, but will have to be played back through a suitable Dolby Digital decoder via digital outputs on a CD player (does not work reliably) or from a DVD player.
You cannot do this with a regular Dolby Digital (ac3) stream at all.
This is a multiplexed stream at 16/48, and is unsuitable.
The process must be done from the original WAV files.
