Is there a way to convert 2.0 Stereo to Dolby Digital 5.1? Because i have video that is in 2.0 stereo that i would like to convert to 5.1 DD. Please help. Like is there any software that can help move certain parts of the audio to certain channels for 5.1?
hi there ! Adobe Audition 1.5 (formerly CoolEdit Pro) can do the conversion. if you have a 5.1 surround card on PC . i haven't done it myself, so i can't give a step by step. there is a tutorial to cover this conversion. regards jay4
It's a fudge though. Full of artifacts - saw it at an adobe seminar, and it's nowhere near as good as actually extracting the audio properly.
hello wilkes ! i wasn't too eager to do it in Adobe Audition even though i have the programme. there seemed to be too much mucking around just for one procedure. when you say extracting the audio properly i guess you mean using wavelab 5 or discWelder Chrome ? weezal could benefit more from your input than mine, as this is one job i haven't done yet. when i do do this coversion, it will be with DVD-A and you've put me into learning curve/search mode already. regards jay4
Not sure if you can do this in WaveLab 5 - I will look into it. About time I got more familiar with the beast. I use Nuendo to do this. Generally record the original in to 2 tracks, and muck around with one of them to get the surrounds, then use M/S processing to export/import a centre channel, route the lot to a 5.1 output, only using 5.0, (not going into that one just now) and sort out the balances so everything sits just right. Then use the Nuendo DDE/DTS encoders, or export the split WAV files and write DVD-A with Chrome. If I use MLP encoding, I can get around 5 surround albums to a single disc at 24/44.1 or 24/48 resolution.
hello wilkes ! there seems to be a lot of work involved mixing wave to 5.1 surround sound. in your opinion what is the best output to listen to. 24/192 DVD-A stereo or 24/48 dvd-a 5.1 surround ? if there is not much difference i personally will stick to the DVD-A stereo format. unless i got it wrong, i believe the 5.1 surround is somewhat a "lossy" format compared to stereo sound ? could all this be done using just discWelder Chrome and Surecode MLP ? thanks again jay4
Okay. What I think you are referring to with 5.1 being "lossy" is DVD-Video 5.1, which uses DTS or Dolby Digital as the carrier. These are indeed "lossy" codecs, but with DTS then I seriously doubt you will actually hear any difference! Chrome & WaveLab both author DVD-Audio, which does Not use lossy compression. It uses full bandwidth, uncompressed PCM WAV files. Therefore, surround at 24/48 in DVD-A is way, way better than stereo IMHO. If you have both Chrome & SurCode MLP, then you can use 24/96 surround too. I honestly believe that 24/192 stereo is not audibly different to 24/96 stereo. There may be stuff up that high, but only a dog will hear it, and wether or not there is anything up that high that is musically relevant is well open to debate. Even manufacturers are starting to agree with this. My advice is to stick to 24/48, or even 24/44.1 in DVD-Audio in both stereo & surround. Chrome & MLP encoding will double the amount of music you get onto a disc at this resolution, and the real quality increase comes from using 24 bit over 16 bit, not the samplerate. To gain any advantage from higher samplerates you will also need an amp & speakers that go up that high too, and nearly all consumer equipment goes no higher than 20KHz on the top end, making higher samplerates utterly pointless. I have made some superb quality Surround & stereo material at 24/44.1 and 24/48 using Nuendo/Chrome/SurCode MLP. If you need more info, feel free to ask away. There is a way to extract surround info from stereo files with Nuendo, and I may well write a guide to doing this. It does require some serious mucking around though, as well as a fairly good monitoring system. It can be done, and the more you do it the easier it gets. Surround is well worth the effort, both in DVD-A version and DTS-CD versions. Also, feel free to mail me privately for full details on these apps. _X_X_X_X_X_[small]www.opusproductions.com Digital Audio Specialists[/small]
hello wilkes ! yes, your quite right, i was getting the DVD-Video 5.1 mixed up with DVD-A. i'll take your advice on the DVD-A surround being better than stereo @24/48. you've obviously done strenuous testing on top equipment to justify the choice(you do it for a living). to do this encoding, you say we need all three --Nuendo-discWelder Chrome-Surcode MLP ? it couldn't be done just using discwelder Chrome and Surcode MLP ? if time would permit wilkes, a guide for a newbie would benefit greatly as the knoweledge myself and my buddies have, well you could fit on a postage stamp. regards jay4
You don't have to use Nuendo - I use the example as this is the app I own. Cubase does just as good a job, andprobably others do too. As for a guide, I don't see why not. I'll try & get one done fairly soon. Maybe even in the next day or two.
hello wilkes ! greatly appreciated. we look forward to that one. i know your a busy man (i wonder why lol) regards jay4
