I think so. I have never experimented with double-layer DVD burning...so you may try and tell us. So, did you successfully burn any standalone player version of wartermarked modification with DiscWelder? It seems there is no software to detect audio watermark right now. Any idea?

watermarked dvd-audio !
when i use the ppcm ripper with orig. dvd-a i become a 2ch wav. 6ch dont work. and when i make a copy with dvd-a ripper, the windvd standig still after 32 sec. but i find a way, to capture 6ch wav from watermarked dvd-a! my way, i use dvd-a ripper,-> i make a iso,-> mount with alcohol und safe the mlp 6ch with dvd-a explorer. after this, i have 6ch mlp with watermarked string. i play the mlp with -> creative media source and recorded this.(option record synchron and record peak check level) i play the record button and the musik play&rec. automatic. after this, i have a 6ch wav 96000Hz 24bit but the header is not good. i play the wav with winamp and i use the "disk writer" plug-in with option, output file mode: force wav file. !!! do not check "convert to format" after this, i have a superb 6ch wav and i import this in "steinberg nuendo" i have a audigy platinum and use the audigy 24/96 asio driver. i save the 6monos and convert this with,-> minnetonka mlp encoder to -> watermarked free 6ch mlp. |

dont work with a watermark dvd-a. with the original dvd-a, i can capture with ppcm ripper only in 2ch mode. (windvd preferences is 6ch mode) and with a dvd-a ripper iso, the dvd-a iso standing still after 32 seconds. quote from ppcmripper "readme" Quote:
ok, my way is not perfect. the a.i. dvd-a has a 88200Hz sample rate and i recorded in 92000 and winamp & steinberg nuendo says 92000Hz 24bit 6ch. Last edited by bonschen; 9th October 2005 at 14:55. |

So, you should make sure you rip a watermarked track and re-record it and then encode it with surcode mlp. Make a multi-channel dvd-a disc with Discwelder and burn it to a DVD-R (or DVD-RW to save research fee). Place it in a standalone DVD-A player to test for the audio-watermark resistance to your manipulation.

Well, maybe as instructed, you cannot rip the DVD-A properly when you have already installed the CREATIVE AUDIGY2 SOUND CARD. To my best knowledge, if de-watermarking is that easy, the author of dvdaripper should have announce the method himself. I think the watermark should still be embedded within your audio track in any format (wma/mp3/wav/ogg...anything you say). You might be interested in buying a second hand DVD-A player at about half-price, for example, a PIONEER. Anyway, the best for now is to build a meida center just like the microsoft-intel joint product. The next generation HD-DVD player would be a multi-media small computer rather than a standalone player. But as a Gold-standard reference, you should experiment with your method and put it to the test with a standalone player.

Some people were saying earlier in this thread how 44.1Khz is full quality anyway since we can't hear higher than about 22.05kHz. However, what you have to remember, is that having a 22.05kHz pitch sound in a 44.1kHz sample rate file will be stored as a triangle wave, being full on the first sample, and negative full on the second sample. Meaning high frequencies have no detail to them.
However at 96kHz, a 22.05kHz wave would be stored more accuratly. It's very audiophiley I know, and the sales of LPs are outsellfing SACD and DVDA combined because people don't really care about the quality, but it's still good stuff to know. Also the supposed "analog warmth" is apparently inaudible high frequencies. |

You should do some more reading on this subject, and maybe some sampling of audio - the 44.1/22.05 isn't khz, it's kb/s, a datarate, which significantly affects the quality of an encoded file.
Edit: Never mind, I got them backwards, sorry. Even so, a 96 kb/s 22.05khz file won't reproduce great audio. Last edited by CWR03; 11th October 2005 at 22:06. |

The flaw in your example is that the output of the DAC is fed through a 22.05 kHz lowpass filter. Since all the harmonics in your triangle wave are above 22.05 kHz, they are filtered out and just a pure 22.05 kHz sine wave remains. Google for Nyquist. There are many detailed explanations available. |

EDIT: Anyone noticed how this has like totally dissapeared? Searching google for anything related to DVD Audio ripping brings up loads of sites with software that rips the audio from DVD-Video discs ¬_¬ It's like a conspiricy =/ Last edited by Qjimbo; 13th October 2005 at 15:46. |
