How to extract the audio from a DVD?


[link to this post]
 
Sometimes when we're going out we want to record a radio programme. We do this by using our DVD recorder to record the Freeview transmitted programme onto the recorder's HDD. I can copy the programme to a DVD but can't copy the sound only to a CD. This is a shame as sometimes we'd like to be able to listen to the programme in the car.

What free software do folk recommend to extract the audio to, say, an MP3 file?

And how does it cope if the programme on the DVD is spread over a number of .VOB files?

Found an Audacity import add on, FFmpeg, which reads a .VOB file and produces the sound data. Can then save, copy, paste, whatever with Audacity to achieve all that I want. I think...

I use DVDDecrypter http://www.dvddecrypter.org.uk/ to copy DVD titles, chapters and audio tracks to the pc's harddrive (.VOB's will be handled as per a DVD player or individual .VOB's can also be selected.) The audio may be ac-3 in which case an audio converter will also be needed that supports ac-3 and can export as mp3 or burn to a cd using the audio cd format. The free version of WavePad will do that http://www.nch.com.au/wavepad/index.html from the "Get it Free" download link.

Alternatively can you simply record the audio whilst playing the DVD on your computer using any of your sound cards functions to, for example, the .wav format and then convert that to mp3 or burn it to a cd with software such as WavePad?

Please report back on the Audacity add on - sounds (excuse the pun) very interesting...

Never used this, but thought this might be of help for editing .vob files.

VobEdit 0.6
A tool for joining, cutting, de-multiplexing DVD VOB files.

I found this thread which told me about the FFmpeg add-on for Audacity. I couldn't get it to install and (to be honest) lost track of where the avformat-52.dll file was. I did a search of the C drive and found a whole folder smile named ffmpeg under the FreeFileViewer folder. So it must have already been installed by that program. I pointed Audacity (V2.0.0) at it and it all worked just fine.

I'd already seen this post but decided that having to play the DVD and get Audacity to record it would be excessively long. Using FFmpeg I was able to open the .VOB file on the DVD, which was about 50 minutes long, and Audacity pulled in the audio in 1 minute, much quicker grin.

Many of the audio and video programs are just front ends to ffmpeg or to VLC. You may find your ffmpeg.exe in various places on your machine (I have 3 at the moment).

You can also call them directly from a command line or command file, but requires some awkward details.
I have set up command files and set them up with a right click menu button in explorer to convert arranged them to exctract the mps from the dvr-ms files my tuner captures from radio or tv.
This is then very convenient in use, with extraction or conversion launched directly from explorer.

Here are some extract that may help: each is a single command line with short comments; use 1 of the three, not the whole thing ....

Sounds good smile

With DVDDecrypter one can rip the audio only from an individual DVD title to the pc harddrive rather than from the .VOB (or .VOB's) though....the audio will be remain unchanged as ac-3 2, 2.1, 5.1; .mp2 stereo; etc.

Yes indeed, and as it's now in Audacity you can save it in whatever format you want.

I'd already got software that allows me to rip the occasional DVD, I got it via here.

That link now points to using Handbrake here. Haven't tried that approach, must do so though.

Thanks for that. I hadn't said that it was for a PC but, hey there are an odd few folk here using MACs so may be of use to them. grin
