5.1 wav or 6 mono wavs to 5.1 Ac3 conversion

[Adhishyajnik]

Yeah, I mixed the sounds in Adobe Audition and exported as 6 mono waves. Then I made them into a .mux file and put it through besweet as per the instructions in the earlier posts. I got an AC3 file that IS 5.1, and does play in Media Player Classic. It just doesn't work in Encore.

If BeSweet doesn't produce compliant 5.1 AC3s, is there any other way to create a 5.1 AC3 that Encore will handle, apart from the Surcode Plugin?

Try using QuEnc.

I used Encore 1.5, not 2.0. Maybe that's the difference. I've been creating 5.1 DD files from BeSweet and importing them into Encore 1.5 for a year without any problem. Maybe there is a conflict with some other program running in the background. Maybe Encore 2.0 is not compatible with BeSweet 5.1 files.

If you wish, I could send you a small 5.1 DD BeSweet file I've created, and you could try to import it into Encore 2.0. That would tell us if it's the BeSweet product itself or if it's something you're doing. Let me know.

Well, I did it using the AviSynth script in QuEnc like gadgetguy suggested, and Encore 2.0 accepted the file fine. The only thing is that it doesn't have any 5.1 options for transcoding. And it's not letting me avoid transcoding it, so that's where the problem is now.

Does Encore 1.5 have a transcoder that preserves 5.1? Because all the transcoders in Encore 2.0 (Dolby Stereo, PCM Stereo, MPEG-II stereo) downmix to 2.0 from 5.1.

Thanks!

It shouldn't be transcoding it at all. 1.5 does not have a 5.1 transcoder either. Sorry I can't offer any more help than that.

Well, there is an option called "Don't Transcode" for any asset, but it's usually grayed out, even with this mpg.

Are there any other audio codecs that you can put into the plugins folder for Encore or some other such folder, or perhaps the registry or something that would add 5.1 encoding to the list of options?

Or are there any other good DVD authoring programs that can handle 5.1?

Or what if I allowed it to transcode, and then I replaced the AC3 in the "transcodes" folder of the project with a 5.1 AC3? Although I would then need to find a way to extract the AC3 stream from my MPG... I've read that VDubMod can do it, but I doesn't look like it has the capability to just export audio. How would I do that?

Well the way I do it using Besweet, you use the .mux extension. Go to your folder where the mono wavs are and open up notepad and type the path for each wav file.

Example

d:\audio-FL.wav
d:\audio-C.wav
d:\audio-FR.wav
d:\audio-SL.wav
d:\audio-SR.wav
d:\audio-LFE.wav

Then save it adding the ".mux" extension. Open up this file in BesweetGUI. Go into the AC3/OGG/PCM section. Click on AC3 encoding options - set your bitrate and tick the "create 5.1 AC3" box. Set any other additional option you want to do, and when you're ready click on the "MUX to AC3" button.

I found this to be a very sweet procedure . It worked perfectly for me. Thanks Much Pinstripes, very impressive indeed. I left Besweet alone some time ago. I found it was either unstable or very particular. I'll see how it holds up for making my ac3 5.1 audio streams.

At the moment of this writing the latest versions still seem to be BeSweet[/URL] 1.5b31 and BeSweetGUI[/URL] 0.7b4. I did some testing and converted 6 WAV files into a single multichannel 5.1 AC3 file and then converted this AC3 file back to 6 WAV files (using BeLight 0.2.2.0 RC1) and compared them to the original 6 WAVs. I noticed that the converted WAVs were of lower volume and they also had their wave sinuses flipped. Obviously BeSweet doesn't do a very professional job at encoding AC3 files.

AC3Tools Pro 1.21.96 don't flip the wave but the volume of the AC3 file is still decreased. Luckily it has a built-in gain option so you can set it to amplify the volume as it encodes to AC3, producing a good result. It also allows you to manually specify which mono WAV file will act as which channel (L, C, R, SL, SR, LFE) and you can select other variations of AC3 output file as well. This is currently my favorite way of converting multiple WAV files to multichannel AC3.

This is a waste of time, you will lose dynamic range from converting to AC3. Try converting to DTS HD-MA instead, it preserves dynamic range, and it's lossless too.
