DVD to CD audio only

[andy jackson]

Hello everyone,
I have a question.
I have a DVD.
I want to take the audio off of it. I would like it in mp3 or wave file format. And next, to burn that audio to a CD.
I want to have the best audio quality possible.

How do I do this?
The software I have is: NERO 2017 Silver, DVDfab(complete), DVDfab Passkey, ImgBurn, Freemake Video Converter

Thanks for your help.

You can use the freeware VLC media player to stream the DVD audio directly from a DVD disc to a audio file.
You can choose several audio formats to convert to.

If you need to edit it, try Audacity.

If you want to convert to CD audio discs, maybe EZ CD Audio Converter. Never tried it, though.
I usually leave the audio file in MP3 format and all my players accept that.

EDIT: VLC can also convert DVD audio to: Vorbis (OGG), MP3, MP3 (MP4), FLAC, CD, WAV audio formats.

Another way is to use MakeMKV and extract the audio file/s then make a CD

Do -NOT- encode to mp3 as your intermediate, if you want the best quality available.

Note, the best quality AVAILABLE would be equal to its source. In this case, the source might already be compressed and thus reduced somewhat in quality. So you CERTAINLY don't want to be FURTHER reducing the quality by re-encoding to another lossy format such as MP3.
AudioCD uses uncompressed LPCM (similar to most WAV or AIFF files).

One thing you WILL have to do to the signal, making it not identical to the source is changing the sample rate. Dvd uses 48kHz (or alternately 96kHz) as their sample rate. AudioCD always uses 44.1kHz. Since there is little common to both of them, you would need a good, sophisticated samplerate-converting algorithm with proper phase-linear pre- and post-filtering.

This means there would always be a slight amount of loss. But you can make it minute with the proper tools, and keep it that way by keeping it LPCM. Btw, while you are doing the SRC, that would also be the time to do any normalizing necessary maintain the dynamic range budget along with appropriately dithered down-rezzing of the bit-depth (since CD requires 16bit).

As Cornucopia well said, forget the mp3 format, if you need a compressed one, use AAC+QAAC. Inside MeGUI tools folder there is a tutorial on how to get it.

I've done this to some of my Elvis DVD's, You'll have to find a way to decrypt and dump the DVD it in to your computer, there is tutorials and tools available for that on the web.
For audio conversion I use this script:

Tools needed:
Wavi: https://sourceforge.net/projects/wavi-avi2wav/
Wavgain: http://www.rarewares.org/others.php
NicAudio: https://archive.codeplex.com/?p=nicaudio# (Install the plug-in at the Avisynth plug-in folder)

DVD2CD.avs

video = BlankClip()
audio = NicAC3Source("D:\your_ac3_track.ac3")
Import("AC32WAV.avs")
AudioDub(video, audio)

At the command prompt extract the audio with:

wavi.exe DVD2CD.avs CD.wav

Found PCM audio: 2 channels, 44100 Hz, 16 bits, 58.656009 seconds.
Writing WAV file "cd.wav"...
WAV file written successfully.

Fix the audio gain and DC-Offset with:

wavegain -a -y cd.wav

 Analyzing...

    Gain   |  Peak  | Scale | New Peak |Left DC|Right DC| Track
           |        |       |          |Offset | Offset |
 --------------------------------------------------------------
  -2.27 dB |  27880 |  0.77 |    21468 |    0  |     0  | cd.wav

 Recommended Album Gain:  -2.27 dB      Scale: 0.7700

 Applying Gain of -2.27 dB to file: cd.wav
This file  98% done     All files  97% done
 WaveGain Processing completed normally

At this point you have a WAV file that follows Audio CD standards, if the software you use gave you or allowed you to export the time stamps, you can use it to create your CUE-Sheet.
Open EAC, press CTRL+E to load the WAVE file, CUE Sheet, Create New CUE Sheet. Here you can set the tracks timings, I do this with the help of Audacity to look at the waveforms to precise find the tracks.

This is how I do it, maybe there is another easy way to create the cue sheet that I'm not aware of.

Extract audio from DVD (you didn't specified if this is DVD Audio or DVD Video - i assume DVD Video).
If you have ffmpeg with enabled libcdio this can be single step operation (you can build such ffmpeg by using easy https://github.com/jb-alvarado/media-autobuild_suite ).
If not then you must rip DVD to HDD and after all you can perform conversion to CD Audio format (2 channel, 16 bit LPCM, 44100Hz sample rate).
It will be good if you can share information about your source (how many channels etc) then some optimized ffmpeg command-line can be created.

Bellow general ffmpeg syntax that works with multichannel audio sources (tested with Dolby Digital, Dolby ATMOS & other up to 7.1), i like shibata noise shaping curve - feel free to change, audio is normalized to -3dBFS peak-peak (always safe).

You can use the Free Studio tool DVD to mp3. In the upcoming window choose wav instead of mp3. You can burn it with Imgburn.
