Extracting audio with VirtualDub

[RedPenguin]

I want to rip out the audio of my TV shows with VirtualDub.

I basically, want a nice format that sounds good but it doesn't have to be 320kb/s. I want to be able to put it on my Creative Zen Vision M (mp3 player) and listen to my shows.

Do I need to do conversion and compression?

There are so many different options, I just need some general guidance.

What's the audio codec and bitrate in your tvshows video? You can identify it with gspot.

Since you mention "VirtualDub", I assume you're talking about AVI videos.

Most AVis have audio in MP3 format.
Quite often this is 128kB.

So no point in going to a higher rate,

Several ways to demux.

E.g., in VirtualDubMod:
Streams
Stream List
Demux

And you'll have an MP3 (most of the time).

If you can use command line,
Get avi2raw from
http://pbx.mine.nu/w21sa/mpeg4ip.html

And use this batch file to extract the MP3 audio from all files in a directory:

@echo avimp3 avifile.avi
@echo demux (assumed mp3) audio from avi files

@if %1X==X goto ALL

:LOOP
for %%I in (%1) do avi2raw -a %%I %%~nI.mp3
SHIFT
@if %1X==X goto END
@goto LOOP

:ALL
for %%I in (*.avi) do avi2raw -a %%I %%~nI.mp3

:END

[Edit: changed VDub to VirtualDubMod; I always use the latter so tend to forget the parent's differences.]

Save as a wav file-then convert(with other software) to mp3 and burn. Some loss of quality with mp3 takes place. Burn as audio cd for better quality, but with fewer tracks.

You can also try AVI2WAV.

I can't remember, though, if AVI2WAV actually converts the audio track of an AVI to a proper WAVE file, or if it just takes the audio track and slaps a RIFF WAVE header on it. Also, I'm not sure how well it works with all codecs in an AVI, or if it works if more than one audio track is present.
Besides, if it is converting to a proper WAVE file, and then you convert it again to an MP3, that's technically a double-reencode, and the sound quality may well suffer. (Yeah, I'm really making AVI2WAV sound like a worthwhile option, aren't I? )

I've been using this app lately.

It's a little slow, but it seems to work fine.

Another vote for the AoA AudioExtractor. Works on a lot of different file types as well.

Thank you for all of your help.

I believe I will use the VirtualDubMod method most of the time, then one of the other methods in case the audio for some reason is not mp3.

I'm starting to like VirtualDubMod. Before I never had a reason to use it, because I use mainly VirtualDub-MPEG2 and sometimes VirtualDub, but I love the Demux feature.

Could you possibly add the MPEG2 to VirtualDubMod by copying over the MPEG2 module?

EDIT: I added the mpeg2 plugin and apparently so far, you can add MPEG2 support to VirtualDubMod.

[jagabo]

VirtualDubMod can read MPEG 1 and 2 video without any plugins.

[RedPenguin]

Oh I feel silly then.

Thanks for telling me that.

Maybe I should start using VirtualDubMod for now on.

Anyone care to say their favorite version of VirtualDub and why?

[Midzuki]

VirtualDub 1.7.7.

I prefer the "pure breed" to the mpeg-2 mods only because
it has an independent Audio menu And requires only
280KB of plugins for opening mpeg-2 and wmv.

VirtualDub, now that it has plugins for MPEG, WMV and other sources, has made VirtualDubMPEG2 obsolete. I still use VirtualDubMod on occasion because of its ability to mux and demux audio (especially AC3) and handle multiple audio streams.
