First of all, this project discusses extracting the audio from DVD Video discs, not DVD-A / DVD Audio discs. DVD-Audio discs use an advanced form of encryption than cannot be digitally extracted / ripped.
Extracting / ripping may be a violation of local laws. These instructions should only be used for content you own and it should only be used for personal use only.
You think to yourself “why purchase both the CD and DVD of a concert when the DVD contains all the audio you need?” Since you purchased the audio on the DVD, it makes sense that you would copy audio from the DVD to your computer / mp3 player without additionally purchasing a CD in addition to the DVD. This page gives step-by-step detail on how to extract the high quality (24 bit / 96 kHz or 24 bit / 48 kHz) 2-channel PCM audio track from a Video DVD and store it in a lossless (WMA lossless, FLAC) or compressed (MP3, AAC, OGG) format.
Step 1: What you need
- A DVD that you own with a high quality stereo audio track.
- If you want to rip the compressed Dolby Digital or DTS audio tracks, please see this page on the SlimDevices forum.
- A PC running Windows XP (older versions of Windows may work as well)
- DVD-ROM drive
- 10 GB (minimum) of free hard drive space
- DVD Shrink 220.127.116.11 DVD decrypter: http://www.dvdshrink.org/
- Alternative: DVD Decrypter: http://www.dvddecrypter.com/
- vStrip GUI audio stream separator: http://www.doom9.org/index.html?/software.htm
One of the following programs (dbPowerAmp is easier to use, LPCM24 seems to be more reliable):
- DB PowerAmp Music Converter: http://www.dbpoweramp.com/dmc.htm + DB PowerAmp Muisc Converter Plugin (Raw Input Decoder + favorite lossless codec): http://www.dbpoweramp.com/codec-central.htm
- LPCM24 24-bit raw stream processor: http://www.rarewares.org/others.html
Step 2: Extract the DVD to your Hard Drive
- Open DVD Shirnk to back-up the DVD to your hard drive. Point it to your DVD drive if it does not auto-detect it. Your DVD will be quickly auto-scanned.
- Click the Re-author button on the tool bar.
- Click the DVD Browser Tab
- Drag the main movie from the right-hand panel (Title 2 below, but what ever is under “main movie”) to the DVD Structure panel on the left.
- Click the Compression Settings tab.
- Under Audio, select LPCM 2-ch and un-select AC3 and/or DTS
- If you want to convert a Dolby Digital or DTS track, it will probably be of lower quality than the LPCM track and will only play back on a devices with the proper decoder. This guide is of limited used for Dolby Digital or DTS tracks. Please see this page on the SlimDevices forum instead.
- Click the Backup! button
- Accept any error message that may pop up
- Select the target directory where DVD will be saved and rip the DVD
- ignore any prompts to burn to a writeable DVD afterwards.
Step 3: Strip the LPCM audio track from the VOB files using vStrip
- Go to the 1 Input tab
- Click the Add… button, go the to directory where you ripped the DVD, and select all of the VOBs you ripped in the previous step
- Make sure the VOBs are in the correct numerical sequence, as shown below. Use the Up and Down or Sort buttons to change the order.
- Go to the second tab 2 IFO
- Browse to the DVD directory on your hard drive and select the IFO file for the DVD you just ripped.
- You should see something similar to what is shown below
- Go to the third tab 3 Output
- Select an output file name (concert name)
- Save it as “Raw PCM stream” file type
- In the “Streams” section, click the None button, then select the SubStreams box
- Select the substream for the audio, for LPCM streams this is usually 0xA0 (PCM Auido Stream 0)
- In the “Output Options“, select the “Demux” box, and make sure nothing else is selected
- In the Split box, select “by CELL-ID” (this will cause the output files to split between each song / chapter)
- Click the Run button to generate the LPCM RAW audio files
Step 4: Convert LPCM into another format using LPCM24
- After the LPCM stream has been demuxed, copy the LPCM24 program into the directory where the file are located.
- Open a Command Prompt window and change to that directory.
- Run LPCM24 by entering:
lpcm24.exe input_file_name.raw output_file_name.wav
- The audio format is usually 24-bit 48 kHz, but sometimes it is 24-bit 96 kHz or 16-bit 44.1 kHz (standard CD quality)
- Now, use DB Power Amp Music Converter to convert the WAV file to your favorite music format. I suggest a lossless format such as FLAC. WMA Lossless is another option. If you must use a lossy format, I suggest a very high quality Variable Bit Rate MP3.
- Now test that you can play the file with your favorite music player (DB Power Amp, Foobar 2000, Winamp, CoolEdit, etc.) If you ripped to a lossless format, be sure that your music player can handle 24-bit 48 kHz and/or 24-bit 96 kHz music.
- If the music sounds way too slow or way too fast, you probably selected the wrong data rate. 24-bit 48 kHz is the most common but if it sounds totally weird, you probably input the wrong format. Convert using a different input type and try again.
