Title: dvd audio creator problems
Post by: panther65 on October 20, 2006, 03:58:57 PM

I burned my long 4gig file with Audio DVD Creator, and the dvd starts 1/4 of the way into the file and there are dropouts. I used a Sony DVD-RW blank disc. Has anyone encountered this problem?

Try Lplex (http://audioplex.sourceforge.net/). The file might be too big for one dvd, though.

Downloaded Lplex. Says press any key to continue, but when I do, the module disappears.

What does it say above 'Press any key to continue?' There should be a message telling you why it didn't author the disc (possibly that it won't fit onto one dvd+r?).

I'm not able to drop anything into the window. Whenever I do anything, the window disappears.

You should pick up the folder containing your wav/flac files and drop it onto the lplex icon, then the window will open up with the program already running.

I think you may be double-clicking on the icon to start the program, and expecting to add your files once it opens up, which won't work because it's not a gui application. It works automatically, you "add the files" by dropping the folder onto it.

That was the answer. I was trying to drop a file onto the window itself instead of the icon. Many thanks Aval for your help.

Will Lplex allow me to drag several tracks into the module? I can drag the entire untracked file into the module, but when I split the file into several tracks, and drag into the Lplex module it won't do anything. It says press any key to continue, and when I do, the module disappears.

Hi panther65. The simplest (and usual) way is to put all the tracks into a folder and then drop the folder. The tracks should be named such that they sort alphabetically to the right order, of course. Any other (non-audio) files inside the folder are considered info files and also transferred to the dvd in a special folder called 'XTRA', so that cover art, setlists, etc can be included.

That's the default behaviour. The readme describes how to change the settings either in the .ini file or from the command line if you're contemplating something more complex.

F'ing cool! I didn't know it would do that.

Sorry to keep badgering you on this software, but when I track in cdwave and then put the files into a folder as directed, Lplex says that the wave header is non-canonical?

when you saved your tracks in CDWave, did you check the "Use Alternate 24bit Format" box? If not, that could be your problem.

No problem, panther65 :)
Convert your wavs to flacs using flac frontend, put them in a separate folder, and drop that folder onto lplex. cdwave is storing extra stuff in the wav headers, which makes them 'non-canonical' and therefore unreadable by Lplex.

Thanks a lot! That worked perfectly. There are setting in cdwave for saving as a flac file, 1-5(I think). They recommend 5 as the best. What do you think?

the range should be 0-8. 6 is standard. 8 gives you a tiny bit more compression but adds a lot more decompression time, though with computers being as fast as they are these days that's no longer much of a consideration.

does Lplex handle inputs of 44k and 48k along with 16-bit and 24-bit ?

what does it output?

Title: Re: dvd audio creator problems
Post by: aval57 on October 28, 2006, 12:35:27 AM

Input types must be DVD-V compliant: ('+' means supported by Lplex, 'Yes' means allowed by DVD-V):


         Rate  Depth   :   Channels
         (khz) (bits)  :   1     2     5(+1)  8
         -------------------------------------------
         48       16   :   Yes+  Yes+  Yes+   Yes+
                  20   :   Yes   Yes   Yes    -
                  24   :   Yes+  Yes+  Yes+   -
         96       16   :   Yes+  Yes+  -      -
                  20   :   Yes   Yes   -      -
                  24   :   Yes+  Yes+  -      -

so no 44khz because DVD-V standard doesn't allow it. (that's the main drawback of DVD-V as compared to DVD-A). Its main features:

Authoring:

Lplex outputs an audio-only DVD-V if you drop a folder of wavs or flacs onto it.
By default it embeds tags (containing audio md5s and original filenames) into the dvd for future reference during extraction, and includes any non-audio files present in the folder as info files in a special 'XTRA' folder in the dvd (the idea is to create a playable archive disc).
Playback is gapless by default (unless you specify that it's a compilation with gaps). To achieve true gapless playback it shifts the track startpoints slightly so that they come into alignment with an immediate video frame (very similar to sector boundary alignment in cd-audio), and this shift is also recorded in the embedded tags for reference during extraction.
The default video is a black screen unless you supply it with a custom jpeg to use as a background.
You can create multi-title dvds from the command line, i.e. fit several shows onto one dvd. Pressing 'menu' on your remote jumps playback forward to the beginning of the next titleset.

Extraction:

If instead you drop a folder containing a DVD-V file structure, or put a dvd into your dvd drive and drop that (i.e. drop a VIDEO_TS folder or its parent), Lplex extracts any unencrypted lpcm it finds to either wav or flac, according to your preference.
If the disc happens to be Lplex-authored, it also verifies the wave-data md5s, reverse-shifts the track startpoints back to their original locations, and restores the original pre-authored file/folder structure for you, including any info files that may have been present.

All of the settings above can enabled/disabled by editing a text format configuration file, or running lplex from the command line.

See the readme (http://audioplex.sourceforge.net/doc/readme_Lplex_0.2_beta_win32.txt) for complete details... :)
