demux/extract soundtrack from avi

[janosch]

:confused: i made nearly 2 years my DivX movies with AC3 and it was never a problem. I use SPDIF-Out but it works also with any other setting.
Yesterday i made a movie with 2 AC3 Streams, it works god.

janosch,

Consider yourself lucky, the rest of us haven't been as fortunate.

Nice thread!
Some statistics:
10 times (!) asked "demux ac3 from avi"
4 times asked "demux mp3 from avi"
9 times answered "Read the FAQ":D

[Nocturno]

lol .. this thread is so funny.. al those people asking the same question over and over while the answer has been posted on the first page..


my 2 cents..

use virtualdub to demux, rename to ac3 and use besplit to correct the header..

how to use besplit..:


READ THE FAQ ..

[MaTTeR]

Hehehe..yes it's very comical.

Yet again another easy way to demux the files properly and in 1 step might be to use AVImux.

Who can answer How to separate Audio and Video Files in AVI file?

[DJ Bobo]

Use AVI2WAV to get the audio.

Use VirtualDub to get a video-only file.
It's very easy, just set video -> direct stream copy and Audio -> No Audio, and then save to a new AVI. You're done.

How can I extract the ac3 stream from an avi with ac3 audio? Can I do it with Nandub? I only need an audio.ac3 file from a video.avi file.
Thanks

you can't unless the person who muxed the AVI used ac3 instead of some other audio format!

Is there a way to save to a separate file only the sound part of a avi movie without converting to wav, but retaining its original format like VBR MP3 or CBR MP3?

thank you

[tiki4]

Yes. Using VirtualDub(-Mod) and direct stream copy. You always get a WAV header though. If you want to remove that, just use BeSplit with the -fix switch. You just have to select the right type (like AC3, MP3).

That's it.

[N_F]

I'm not sure, but I think VirtualDubMod demuxes tracks properly (without adding a wav-header that wasn't there earlier).

[tiki4]

Sorry, I don't know. I never tried, but I think you are right.

[alexnoe]

MP3, AC3 and DTS can be extracted using AVI-Mux GUI

[tiki4]

Of course.

I think your very nice tool is often overlooked. I think you need to advertise even more.

tiki4

[kuliman]

humm... finally i know what demux does, it works perfect in Virtualdubmod. About Avi Mux Gui, i tried it but did not found any option to do the demux thing. If someone can tell me how.

Thanks

[alexnoe]

As almost everything => right-click!

[kuliman]

it does the job but... when you open a file instead of showing imediately the awailable streams you have to click one more button (add video source) you could avoid that, i think...

[alexnoe]

yes, as soon as i find the time...

Hi there,

is there a posibility to extract the ac3-stream again out of a xvid file? So far, I´ve tried besweet, but I didn´t succeed! I think it´s because besweet can´t handle the avi-file!?

Thanks for all hints!

This question have been asked ~10 times in this thead and have also been answered a number of times... anyway, VirtualDubMod should be able to help you. If not, read through this thread and you'll find several alternatives.


To any moderator that feels hit: For the sake of my sanity, the last ~5 posts of this thread was moved to this older thread, correct?

[Sycho]

I have a DivX AVI file, and it has VBR MP3 audio(48kHz approx 127kbit/sec). I am looking for a program that will convert it to *.wav(24kHz 16bit Stereo). The reason for this is that the MP3 decoding slows down my computer. Does any one have any suggestions, any at all?

[Awatef]

use avi2wav to extract

rename to mp3

use razorlame to decode to WAV

mux the WAV with your AVI

[Sycho]

thanx

Hi ppl,

I've read the following guide and i have some doubts.

http://www.doom9.org/virtualdub_procedures.htm#ac3extraction

When I extract the AC3 5.1 audio from the .avi file, can i use VirtualDub instead if nandub with the same process? (since I can't get it to work)

Will VirtualDub 1.5.1 handle the ac3 audio correctly or will I lose 5.1 quality converting it to .WAV ?

Next, to create a DVD I have to run BeSliced to convert it to .ac3 and drag it in DVDMaestro, right?

Thx in advance

[\AX]

Listen...they are just teasing you...and its getting old.

Ok to demux a .ac3 from a .avi take a sharpie pen and
mark out the last 1/4 inch of the cd COMPLETELY!
If you get choppy play back then you missed a spot.

Demuxing a .mp3 from a .avi is the same thing...but
mark out the FIRST 1/4 inch of the cd. (VBR .mp3 requires
a steadier hand :-(

If...and ONLY if...you got MPEG2 audio..this will NOT,
i repeat NOT work. For that you have to read the FAQ
or cut the cd in half. (whatever is quickest).

after that just read the cd like normal ;-P

your welcome in advance.

(almost forgot...thanks. I was looking for this information
and it was quick and to the point (Atleast in the top part
of page 1))

Hi folks!

New to the boards and I was hoping that you could help me out with something.

I was wondering if it is possible to extract the music only from a movies soundtrack?

Recently, I've become incresingly annoyed with official OST releases for movies. They never feature all of the music from the film and invariably, the best bits are always left out.

I've got a hold of some complete scores for movies off the net, so I was thinking that it must be possible to rip them somehow, as these scores that I've downloaded are not available on CD in a full format.

Can anyone give me tips on how do it? What programs will I need to do it? I have GordonKnot on my computer to rip DVD's, but do I need specific software to isolate the score, or is there stuff on GordonKnot already that I just haven't noticed?

Any help you can give would be very, very much appreciated - you'd be making this movie fan a very happy person indeed!

:)

P.S - I apologise in advance if there is already a thread that deals with this query, I haven't been able to find it. If a thread about this does indeed already exist, if you could provide a link I'd be much oblidged. Thanks.

Hi BOCfan, and welcome to the forums:

First of all, you'll want to have another look at the forum rules you agreed to when you signed up. Any talk of downloaded and copyrighted material is prohibited here. http://forum.doom9.org/forum-rules.htm

As far as actually extracting music-only from a movie soundtrack: there isn't an easy or exact way to do it. As far as I know there are only two options:

If the soundtrack is a 5.1 surround mix, as is common on DVDs, you can separate the channels and get rid of the center channel, which in some cases, will contain most of the dialogue and non-music effects. This can be done with BeSplit or any other tool that can separate AC3 into mono .wavs. Drawbacks of this method would be that sound effects will still be included, and dialogue may be as well, depending on the mix.

A second possibility would be to decode the soundtrack to a .wav and open it in a sound editor like Cool Edit Pro. There are a number of vocal removing plugins that work on the basis of dialogue and music being encoded differently in a stereo file. Drawbacks of this method would be that the sound will, in most cases, sound very different from the original, usually not very pleasing.

hth,

[BOCfan]

Thanks for the welcome, and I'll be sure to heed the rules on copyright.

I'll try Beplit and let you know how I get on.:cool:

Is it possible to rip out a sound from a movie and edit that?
I have a movie where the sound is to low.

Is there anyway I can rip an ac3 audio track from an avi so that I can create a dts cd with it.

[Tuning]

You can demux ac3 from avi using VdubMod.Open the Avi in VDM,in stream -> stream list ->select appropriate stream(ac3) -> Click Demux.

I just bought a dvd burner, and now i want to change all of my divx movies back into dvd's. I have ben trying to use EoH guide to change the stereo to 5.1, but when I try to extract the audio it won't work because it is a VBR MP3. Does anyone have any suggestions for me on how to do this? thanks, iSpy

[echooff]

Load you avi into VirtualDub Select audio->full processing; File->save wav; give it a new name and click ok. Also welcome to the forum. Remember to follow the forum rules in particular:
1) Read up before asking! There are tons of guides, FAQs and each forum has a dedicated Q&A thread with additional info.

1a) Use the search function before posting. Chances are your question has already been answered.

[iSpy]

Thank you for your reply echooff. First of all virtualdub won't process VBR Mp3s. I tried it and it won't work. then I read up on virtualdub and what I read confirmed what I found out when I tried it in the first place. the virtualdub can't process Vbr Mp3's. that is why I asked the question. I have read everything that I can find on this website and others about this subject and I haven't gotten a clear answer or solution. Doom9 definatly has the most information on these subjects, so I came here to the forums for some help, thank you for trying to guide me in the right direction. I will continue to look though the extensive info on this site but as of yet haven't found the info I am looking for.

Thank you for your suggestion, I just tried it and it still didn't work. Virtualdub starts the transcode but the either hangs of gives me an error.

[KpeX]

Try VirtualDubMod. And also please read the audio FAQ, especially #4.
