DVD Audio Layout
Normally, 5.1 audio on DVDs are isolated into six tracks. The first two usually have music and sound
effects separated. Track 3 is the mix that you hear in the film containing the music, dialog and sound effects. Track 4 can be tossed. It's normally empty, though you will sometimes find a sound effect in there at times. Tracks 5 and 6 are rear channels and mostly sound tinny. But, some DVDs have this
track configuration reversed. The “Elvira, Mistress of the Dark” DVD falls into this catagory. Tracks 5 and 6 were the isolated music and/or music-sound effects segments, instead of tracks 1 and 2. There
are many DVDs that claim to be 5.1 audio, but are not. Instead, each channel is the same thing. John Ritter's classic comedy, Skin Deep, is a disc like that. "Bill & Ted's Excellent Adventure" is another.
Using the DVD Audio Extractor
1. Insert a 5.1 audio DVD of your choice and start up the program. Now choose the title that has the
movie in the section.
2. Choose the English AC3 channel that has the Dolby 5.1 track and not DTS or 2 Ch tracks, if there are
any. No point ripping a 2 Channel DVD since the music, sound effects and dialog are all mixed
together in both channels.
3. Check the chapters you want to rip and press next.
4. Under output format, choose WAV - PCM, sample rate 44100 Hz, channels - all 6 channels, bits per
sample - 16 bits. Check box that says “Save each channel into separate file”.
5. Choose output location (Directory of where you want it saved), have the following two boxes checked
- “Save Each Chapter Into Separate File” and “Overwrite Files With The Same Name”.
6. Enable Normalization and change max level to around 96.4%.
7. Thread priority equals “normal”. Press start.
Using GoldWave
The program can be used to amplify audio volumes (which is always needing to be done), clear away
hiss and background noise, snip things that don't need to be in the song (like sound effects or voices),
and save the segments into their new track arrangement for the soundtrack(s). I also add silence gaps
at the beginning (.5) and end (1.0), depending on the length of the track. If it isn't any longer than 1
min., then I just add a (.5) sec gap on the end.
Concerning volume amplification, use the "Change Volume" button (has a small circle on it) and adjust
to the waveform to be below the top and bottom borders of the windows. Sometimes you don't need
to go that high. Other times, I just use "MaxMatch", which actually is needed with most MP3s, since it
makes the left and right waveforms (top and bottom in the window) match in volume. If the peaks of
the waveform go above or a lot touch the borders of the window, drop the volume down a bit.
Normally I use -1.77.
You save mono files as stereo. When you “Save As” (if you don't have that button, open your Customize
menu and put it up there on your toolbar. You'll need the "Insert Silence" button as well. To customize
your toolbar, click on "Options" and "Toolbar". Then you can delete or add buttons), at the bottom of
the save window is an attributes bar. Click on the black down arrow to its right and choose your format.
Since you like 320, choose "Layer-3, 44100 Hz, 320 stereo". 48100 makes an MP3 quite big and I've
never heard any difference between 44 and 48.
When editing 5.1 audio tracks that have been saved to mono .wav files, I don't mix them into stereo,
just save them as 2-channel stereo, which is the normal output. The sound quality doesn't change, only
sounds better since you are getting it in stereo. After you open a mono .wav file, edit it like usual and
then save in stereo. IMPORTANT NOTE: Be sure to amplify the volume level in mono first, otherwise it
has a tendency to screw up the sound. Once you do so and save into stereo, then you can alter volume
levels without problem.
