Audio extraction with Virtualdub

[jakers]

Can anyone tell me the proper way (to produce good results) to extract audio with Virtualdub. It can't be as easy as File - Save wav. I've been reading about filters and such and would like directions.
thanks,

In most cases, it is that easy. But VDub is not served primarily as an audio editor. For that purpose, you might need other tools.

Yeah, something like besweet maybe....

so........what should I do first. I am so new......

I thought that I would extract audio (save wav) in virtualdub first before i start the tmpgenc stuff. Should I do the besweet instead of virtualdub? If you can lead me to or give me directions that would be great.

Thanks so much.

the way i do it is export the sound as a WAV from VDub, then run that through BeSweet to convert to 128k Constant Bitrate MP3....pretty easy

I'm not sure what my audio is from my file source. I know how to check that, but I don't know how to interpret that from VD -- File Information.

If I'm wanting to convert my divx kazaa files into dvd, don't I want that in the AC3 format (whatever that means) rather than mp3? Just asking cause I don't know. Don't want to run through besweet after virtualdub if it will be wrong.

I really appreciate you guys helping me. PS. My first tmpgenc conversion is supposed to be done in 15 min????????!!!!!!!!!! yeah!

careful, movies downloaded from kazaa (or any other online source) is considered warez and you will be warned about it.

[jakers]

oooopppsss. sorry. downfall of being a newbie.

Any suggestions on the extraction steps would be great. I think there's more to do then just save wav through Virtualdub, but I don't know what.

I want to make a dvd.

Thanks sooo much.

well, if your avi has .ac3 sound you can use vitual dub with the audio set to "direct stream copy" and then save wav. this will give you movie.wav which you can rename to movie.ac3 and use in an authoring program.
If the .avi has MP3 sound (this is the most likely) then audio-full processing, save wav. you can now input the wav file to tmpgenc as the audio source along with the avi as the video source.

Thanks for your reply. I'm not sure what my source audio has/is or doesn't/does? Can you tell me what I can do to find out? I know how to get file information from vdub, but don't know what or how I should be intrepreting the info?

Thank you so much

i highly recommend that you download a program called GSpot.....it's a very useful utility that will tell you the audio and video formats, as well as other useful info

GSpot is useful if you're working with AVIs.

If you can view (and listen) to the AVI file with Windows media player it means you have the appropriate codecs installed. In that case, VirtualDUB will be able to show you (File-->File Information) what codec was used for the video and audio.

If the audio is MP3 then you can save the WAV file through VirtualDUB. In many cases recently people encode AVI files with audio in AC3 format.

In almost all cases I've encountered so far, I've been able to process such files with the modified version of VirtualDUB that can handle MPEG-2 video and AC3 audio. It can also handle (e.g. DivX video and AC3 audio).

In the rare case where VitualDUB fails, you can always start an audio recorder and then play the Video. The audio recorder will record what audio is played back. Stupid primitive method but it works as a last resort.

You've had the most understable reply (for me) yet!! Very appreciative. In the meantime, I downloaded something called AVICodec and that seems similiar to GSpot (although, I really have no clue). All of my video files (divx and xvid) have the audio compression of: Fraunhofer IIS MPEG Layer 3 Codec, 0-bit, and Channel 2 Stereo. With that in mind, what do I have? I don't see mp3 or ac3 anywhere.

1. what do I want to convert to if my target is dvd? ac3?
2. do i extract anything more than a wav file from virtualdub? ac3?
3. Alot of people are telling me that i need to run the file from #2 thru Besweet.

I hope eventually this stuff will get thru my head and I will start to understand. I do think I'm breaking a small barrier though.

THANKS AGAIN

[flaninacupboard]

MP3 is an abbreviation (and filename extension i.e. movie.mp3) of MPEG Layer 3 Audio.
So, you have MP3 audio, so opening in virtual dub and selecting save as wav is all you need do

[jakers]

Bless you. Really, is that all? Simple as going into tmgpenc and saving wav??? Even if I want a dvd as my result? What about going to audio and doing all that "stuff": full processing mode, no compression, filters, etc? (as in step #4 of funkguy's guide). Also, what about this besweet program everyone is saying I should run the wav file through?

You have no idea how happy I am to finally be getting to the "end" of the audio extraction part............now if I can figure out authoring and burning!!!!!!!!

[funkguy4]

BeSweet is the ultimate freely available audio compression engine! It will take your big-ass WAV and make it into a fully compatible AC3 or MP2 or MP3 or whatever you damn well please (within reason)! There's a GUI for it........

Don't be mad funkguy.......... I'm really just trying to learn. I know you know what you're talking about, but you are seasoned....I'm a newbie. I'll do my best to work on the things we've talked about and get back to ya. I'm going to take my original audio source mp3 thru tmpgenc, get wav, send wav thru besweet gui and get ac3.

I'll try and make you proud when I learn all of this stuff.....baby steps.....I know.

You're all great. Thanks so much.

Did I sound mad? If I did, I'm really confused............
