AC3 Conversion

[Snipe65]

Hey, i have virtualdub and i was wondering how to convert the audio out of it, i've got the movie to work but the audio still dosen't want to work, and i've tried using the azid converter but it dosen't seem to work or i am doing something wrong, anyone have any suggestions? I am trying to convert Enemy at the gates movie. It uses the AC3 codec for sound.

What format are trying to convert it to??..the Azid I have converts fine to .wav file....then i use toolame to convert that to a mpg2 file

I would like to be able to conver the audio (ac3 codec) from my avi file into the wav format.

Basically just split the avi and the ac3 sound into 2 files

This is my problem to ...have the same movie ...AC3 is driving me nuts .....i did a direct stream copy to wav in Vdub ...but the sound was soooo bad....tryed a million tools. Someone told me frame serv from Vdub...but how do i do that ...only get the video fron Vdub then

Try demultiplexing your audio.

This should be an AC3 type audio. You can use one of the freeware AC3 decoders to convert it to PCM WAV (e.g., AC3Dec). You can download this from doom9's site: http://www.doom9.net

On DVD ac3 is coded in 48khz. Converting for (S)VCD? Make sure you downsample to 44.1Khz. You can extract and downsample using DVD2AVI.

DVD2AVI will also do a ac3 -> dolby surround audio mix. I don't know the order DVD2AVI handles things. Preferrably this should be:
1. surround mix in 48khz
2. downsample from 48 to 44.1khz

Can anybody confirm this is the order DVD2AVI will do this?

If not, I am looking for a separate tool to convert 48kHZ.wav to 44.1Khz.wav.

Anyone know?

Thanks,

Yes, Dvd2Avi will mix and downsample. It will also normalize. Takes around an hour for the whole process on a 90 minute movie.

The problem with that is that the audio and video are encoded in a divx file and i can't seem to split them, converting the ac3 to wav wouldn't be hard but i need something to split the audio form the video with

I think i have had the same problem before, and I got an advice from someone to use GraphEdit, and that helped me. The program is kinda hard to understand I think, but I managed to rip the ac3 from an avi and save it as a wav, and it worked for me, you can try that prog..

GraphEdit works ...the sound is good and everything seems ok.....but when I multiplex it with the video....at the end the sync is terrible.....so ...is there a way to fix the syncploblem or did i do something wrong ?
