Making a Dolby Digital Audio CD from MP3's?

[samsung27f]

Is there a way to make a dloby digital audio cd from a music mp3 file?

[afwasborstel]

Is the mp3 multichannel? If not.....NOPE!

If u use BeSweetv1.4 u can get a Dolby Digital 2.0.
Dolby Digital 5.1 from a mp3 that is 2 channels is not possible.

It must be possible somehow, how do movie studios take recordings from artists and put them in a soundtrack mixed in dolby digital, there has to be a way of converting a 2 ch audio file into dolby digital, through some algoritihim, that spreads the sound to 5 chanels.

don't know if this is what you want..

Two channels remain 2 channels....not 5 channels...

FYI, Digital Dolby doesn't have to be 5.1. As Man7 pointed out:

Digital Dolby supports stereo reproduction.

Have you ever considered that perhaps for those recordings the recording studio records the audio in 5.1 channels and then downmixes it to Dolby Surround for audio CD??

You cannot split a stereo audio file into discrete 5.1 channels and have it sound "right" every time. This is kind of what Pro Logic II does but it is definitely hardware only.

Dolby Digital need not be only 5.1 but can be straight stereo as well. Why you would want to make a stereo DD CD is beyond me, however (as it would offer no benefits but several disadvantages over a standard audio CD).

BTW, Dolby Digital audio CDs don't really work all that well.

Perhaps you are thinking of a DTS audio CD?

You can make 5.1 DTS encoded PCM files (and hence DTS audio CDs) with SoftEncode 5.1 (a commercial program that no longer sells I think). However, you need to have the audio source of all 5.1 channels.

you can make a DTS audio CD with Surcode DTS in 5:1 which sounds a whole lot better than DD audio cd's (which dont sound near as good as normal audio cd's really)

DTS audio cd's can be 20 bit instead of 16bit

all of the above doesnt help you a whole lot as converting a mp3 to much of anything else will not certainly make it better -- but if you do , keep it at stereo as remixing it to surround may make it sound worse..


some of the 20bit DTS audio cd's sound just amaizing ..

BJ_M, I haven't tried the surcode cd dts but looks like it might take a long process to get a dts cd...surcode need seperate channel input of wav file..from an ac3 file you have to decode each channel using a software like soft encode from sonic to decode each channel..and my understanding is the output of it is a raw file and run cool edit pro to convert each channel to wav file and input each channel wav file to surcode...I haven't tried it myself but sounds like if you have a really good concert dvd the audio cd will be very good too..

just my 2 cents
