In our articles the topic of DVD ripping, in general, is already covered, so be sure to give those a read before you proceed, because we are about to dive deeply in DVD audio ripping as a specific case you might need. More specifically two cases.
DVD-Audio, or DVD-A for short, is a specific format for storing HI-FI audio files. In general DVD-A stores, audio content with much more fidelity than a video DVD would, and is perfect for content such as concerts, albums, movie soundtracks etc. DVD-Audio is capable of having files in 16, 20, or 24 bits, with sampling rates from 44.1khz all the way to the 192khz, and from mono to full 5.0 or 5.1 surrounds, with any combination of above mentioned.
Ripping DVD-A can be a bit tricky and challenging, but with a bit of patience and the right tools, even a PC dummy can learn how to do it. The tricky part comes in a form of a copy protection found on most of these discs called MLP. Only a selected few tools can circumvent this problem without compromising audio quality or degrading it to simple stereo. You will need to download and install the program on your desktop and an optical drive on your computer. Now the next important step is choosing the right, lossless audio format. For desktop use .waw or Wave format is fine, alto large. Others might prefer compressed files such as FLAC or ALAC for apple users. And then let the tool do its magic.
Extracting audio from DVD video
The process is quite the same as you are extracting video from your DVD onto your computer or laptop. The only difference is that you need a special program that will separate your audio into a separate stream so you can rip your audio the right way. The VLC media player is quite good with that and he also separates your audio from its video and then converts your audio in a format that you specified. After that, you can transfer your new audio file onto any device you wish.
