Batch extract audio from multiple DV files?

[Colmino]

Well.. it's finally time to start ripping choice audio clips from my various (~700GB) DV files. Only now do I realize that there is a bit of a stumbling block. I already knew that importing the files into Premiere Pro was a hopeless proposition, because of the necessity of the program to completely analyze the file (or, more specifically, the speed with which it performs that task). I didn't expect Audition to give me the same problem. Right now, it's taking so long to fully import a video into Audition that it would almost be faster just to record them all over again with no video.

So, having resigned myself to the apparent fact that there is going to be a lot of time spent dealing with these files one way or another, I may as well nail down some method of achieving the process without having to baby it. I have plenty of drive space. So what I need is a piece of software which is capable of extracting the audio as WAV from multiple DV (AVI) files.

Of course I could be mercifully incorrect. Perhaps there is a program which can extract the audio just as quickly as any media player can seek all over the DV files in nothing flat. Maybe I'm crazy. Either way, help is appreciated.

I think goldwave can batch demux from avi files to wav.

Or use the command line tool ffmpeg and make a batch(.bat) file. In notepad type

FOR %%F IN (%1\*.AVI) DO ffmpeg.exe -i "%%~fF" -acodec copy -vn -y "%%~dpnF.wav"

(I'm not sure if it's exact correct but google it for more information.)

and save as convert.bat and put it in same folder as the avi. Download ffmpeg windows build and put it same folder. Double click on convert.bat to run it.

HCbatchGUI can do what you want. Your dv-avi files will need avisynth scripts for it to accomplish that but hcbatchgui can do that for you as well.

First select your source and target directories.

Next create your avisynth scripts by checking the noresize box then pressing "Generate Avisynth Scripts"

Then go to the audio tab and near the bottom you will see an option for extracting wav audio for use in an external audio program. You can select to extract as is or extract resampled to 48k. Then press extract wav

Finally just go to the start page and press start the process and watch it go.

May sound like a lot but actually it's rather fast setup. What takes the time is the processing.

It's freeware so you might give it a shot.

I could not make it work with HCBatch - it could not stop complain about files not found.
I wrote a word macro which wrote a batch which worked with wavi.exe directly.

Hmm. Okay. Not sure why it didn't work right for you because I added that function for someone else wanting to do exactly what you are and it worked fine for him.

Glad you have got a working solution now though.
