HELP: Simple way to rip from 5.1 surround to WAV

[kriegerg69]

I've tried several different programs I've read about here and there, and can't seem to get anything to do what I want :(, which is:

A simply way to rip/extract the surround channel information from a DVD into WAV format for editing before I convert to MP3. I would like to do this with some movies I have to have MP3 files of the music.....but can't get anything to work for me. Have a old DVD player with a built-in DD decoder, and a couple of times I was able to record directly from the surround output channels, but now this player has gone bad on me. :angry:

What easy way is there of doing this on my computer with a reasonably easy freeware program? Thanks for any help on this! (Tried searching the forums here and couldn't find a simple, direct answer for what I want to do). ;)

...rip/extract the surround channel information from a DVD into WAV format for editing...I presume you mean how to get the AC3 from the DVD extracted as WAV? If so, DGIndex can do it (Audio -> Output Method -> Decode AC3 Track to WAV).

Uh, no (I downloaded DGIndex and tried it already)....I want to get only the surround sound channel information as a WAV file....not the front channels nor the center, but only the rear/surround channels. I already use DVD Audio Ripper for basic DD to WAV, but I need something to get just the rear channel sound. As I explained in my original post, many DVD's have pretty much just music and some sound effects on the rear DD channels, and I want to be able to get just the surround ripped to WAV to have the music from a film.

OK. BeSweet with the -6ch switch will create mono WAV files as the output in the order FL, FR, C, LFE, SL & SR. Keep the ones you need and delete the rest.

....and how exactly do I go through that?? Please, is there some kind of SIMPLE step-by-step guide here on Doom's site or elsewhere, for that matter. I downloaded the BeSweet.exe and the BeSweetGUI0.6b61.exe, and tried doing a Google search on what the heck to do.....and need more help, please. Simnply telling me what you just did is not helping me here. :confused:

Do I have everything I eed, or is there something else I need to download? :confused:

[unskinnyboy]

OK. Assuming you have basic CLI knowledge, you do:

BeSweet.exe -core -input "C:\Path_to_your_input_file\your_file.ac3" -output "C:\Path_to_your_output_file\output_" -6ch

This will give you 6 files:

output_C.wav
output_FL.wav
output_FR.wav
output_LFE.wav
output_SL.wav
output_SR.wav

BeSweet.exe -core -input "C:\Path_to_your_input_file\your_file.ac3" -output "C:\Path_to_your_output_file\output_" -6ch

This will give you 6 files:

output_C.wav
output_FL.wav
output_FR.wav
output_LFE.wav
output_SL.wav
output_SR.wav

You shouldn't assume something like that :angry:....I have no idea what you're talking about, and have asked for very SIMPLE and basic directions, and described at least twice what I need to do, and you keep giving me gobbledegoop terms which I am unfamiliar with....I know how to do a lot on my computer, but you're not being helpful at all at this point. :(

Does anyone ELSE know how to give me SIMPLE directions for what I need to do?

:rolleyes:


Find this file on your PC and double-click it -> C:\Windows\System32\cmd.exe

This will open a black colored window. In there type: cd c:\path_to_where_you_have_BeSweet_installed\

Now type BeSweet.exe -core -input "C:\path_to_your_input_file\your_file.ac3" -output "C:\path_to_your_output_file\output_" -6ch

Now, use Windows Explorer to browse to C:\path_to_your_output_file\ and you can see your output files.
If you still can't understand, I don't have the time or patience to explain any more. Try your luck with the next person who comes along.

Hi!

1) Download and install the complete BeLight v.0.21/BeSweet package

2) Select "WAV" for output - and either 16 bits or 32 bits

3) Click on the "Input" radiobutton and select your 5.1 .AC3 audio file

4) Click on "Start"

You should now find 6 .WAV files in the same folder as your .AC3 file. Included in each .WAV file's name will be the speaker location...

[kriegerg69]

Thank you, Setarip.....your simple and precise directions are exactly what I wanted. It worked for me for exactly what I needed. :D

It's working like a dream....Thanks! ;)

[setarip_old]

Thank you, Setarip....You're quite welcome ;>}

[kriegerg69]

You're quite welcome ;>}

This is working VERY well for me now.

Now, maybe you or someone else can answer another, similar question:

Now that I've solved my problem of ripping the surround track from a Dolby Digital 5.1 audio track....Is there a way to extract the surround information (and keep it in stereo) from a basic, standard Dolby Surround sountrack? The older process for Dolby surround encoding was to matrix the surround channel information into the two-channel sound for prints distributed to theaters.

If I have a DVD with only the basic Dolby 2.0 surround, or for that matter an old VHS tape in stereo, or a laserdisc with Dolby Surround, is it possible to do something similar to what we talked about here? Is it at all possible to get that "hidden" matrixed surround information out of an older Dolby Surround track? :confused:

You can use GraphEdit and some DirectShow filters like CyberLink Audio Effect (PowerDVD 7) but there are also a free method using Foobar2000 with this foo_dsp_fsurround function (http://www.hydrogenaudio.org/forums/index.php?showtopic=52235)

[kriegerg69]

Thanks, Tebasuna....it seems like Foobar is what I need (I also had to download the two .dll files they said were also needed, but where do I put them...in which directory of the program?)....and like Setarip explained above for BeSweet, can you tell me exactly what steps I need to follow in order to use Foobar to extract the Dolby Surround info from a movie and s=ave it as a WAV file for editing?

Thanks for your help, btw...

Thanks, Tebasuna....it seems like Foobar is what I need (I also had to download the two .dll files they said were also needed, but where do I put them...in which directory of the program?)....
The dll files must be:
...\Foobar2000\libfftw3f-3.dll
...\Foobar2000\components\foo_dsp_fsurround.dll
and like Setarip explained above for BeSweet, can you tell me exactly what steps I need to follow in order to use Foobar to extract the Dolby Surround info from a movie and s=ave it as a WAV file for editing?
1) Load the stereo Dolby ProLogic encoded audio in Foobar2000

2) Rightclick over the audio and select 'Convert' -> 'Convert to...'

3) In the pop-up window 'Converter Setup' select 'Encoding Preset' : WAV

4) Mark 'DSP Processing' and click in '...'

5) A new pop-up window 'DSP Settings - Converter' appear. Select 'Free Surround' at right column 'Available DSP's' and click over '<=' to send to left column 'Active DSP's'. One more click over 'Configure selected'

6) And a new pop-up window 'Free Surround' to configure the dpl decoder. You can see a discussion over the settings in the thread mentioned at hydrogenaudio. My suggestion is:
- Center Image: 1.0
- Dimension: 0.0
- Stereo Separation: 0.0, 0.0
- Steering mode: Linear or Simple (make your test)
- Rear Phase reconstruction: BeSweet compatibility (+180, +0)
- Assumed Mixing Coeficients: 0.866, 0.5

7) Close with 'OK' the 3 last windows and select the desired output filename.

Note: The Assumed Mixing Coeficients and Rear Phase reconstruction are coherent with the method to obtain Dolby ProLogic II downmix with BeLight-BeSweet-Azid 1.9

If the method to obtain the dpl II is the actual BeHappy or, maybe, other commercial tools you can try PowerDVD compatibility (+0, +180).

Also there are other dpl II mix than use Assumed Mixing Coeficients: 0.8165, 0.5774

When the mix is Dolby ProLogic I (Dolby Surround from VHS tapes for instance) we need Assumed Mixing Coeficients: 0.7071, 0.7071 (equal rear channels).

Maybe is not easy but steps 4, 5 and 6 are only needed the first time.

Thanks for the help! I followed your directions, using both an MP3 and a WAV format of an audio file....and what Foobar created for me was an unplayable (tried it in several different programs) wav file which seemed to be 6 channel sound at 4233kbps. There's a file there, but it's unplayable. What's going on? I did set everything up per your step-by-step directions, but this hasn't worked yet.

[tebasuna51]

What is unplayable?

Silence, noise, error message, filesize > 2 GB, ...?

A 6 channel 16 bit 44100 Hz wav have a bitrate of 4233.6 kb/s.

Try you use the wav for a video DVD audio track? (48000 Hz needed)

Foobar2000 can't play it?

[kriegerg69]

Ripped a section of a movie from a Dolby Digital 2.0 (basic Dolby Surround) from a movie, processed it per your directions in Foobar, and I couldn't play it in anything except Foobar. Also, it didn't sound right....don't know how to describe what it sounded like, but when I right-click on the file in Windows Explorer and choose Properties, it tells me the file has six channels of audio. All I want to be able to extract/rip from a basic old-fashioned Dolby Surround/Dolby Pro-Logic soundtrack is only the surround channel and have it as a single file by itself (I guess that would be a 2 channel stereo WAV file). :rolleyes:

Download this info tool (http://www.mytempdir.com/2048795).
Open the original ac3 2.0 and post the info.
Open your unplayable wav and post the info.
