I wrote the CPPM section but I do have one question which I haven't been able to find the answer to: What happens if a hardware player has all its keys compromised? If the keys are revoked, new DVD-Audio discs would be rendered useless on that player, right? Do I have to get a firmware upgrade from the manufacturer? Has DRM turned my DVD-Audio player into a boat anchor? Rhobite 00:59, May 11, 2005 (UTC)
Because DVD-Video's content-scrambling system (CSS) was quickly broken, DVD-Audio's developers sought a better method of blocking unauthorized duplications. They developed CPPM, which uses a media key block (MKB) to authenticate DVD-Audio players. In order to decrypt the audio, players must obtain a media key from the MKB, which also is encrypted. The player must use its own unique key to decrypt the MKB. If a DVD-Audio player's decryption key is compromised, that key can be rendered useless for decrypting future DVD-Audio discs. DVD-Audio discs also can utilize digital watermarking technology developed by the Verance Corporation."
Why is there no regional lockout, if I had developed CPPM I would have included a buit in regional lockout. 144.139.89.254
from what i remember the dvda standard missed being put into all dvd video players because they were not finished with their copy protection. if they had just gone without their installed base of players would be incredible by now, a missed opportunity. —The preceding unsigned comment was added by 75.30.78.7 ( talk) 00:10, 18 March 2007 (UTC).
I'm not particularly bothered about extra quality or different surround-sound formats, I would prefer to have more music on one disc. How many CDs could be fitted onto one DVD-Audio disc using the original quality? -- Phil | Talk 08:10, May 12, 2005 (UTC)
However, 24 bit recordings at 44.1 kHz and 48 kHz are widely accepted to be of substantial improvement to the 16 bit recordings currently available on Compact Discs.
Why ? There's no explanation written for that arguable affirmation. Please add explanation and cite sources. Thanks. -- Hdante 21:26, 22 January 2006 (UTC)
I can't cite sources but it's easy to understand if you think of video instead. Let's say you have a 1-bit video. Each pixel on your screen is either black or white. With 2 bits, each pixel is either white, light grey, drak grey, or black. It'll look better. 3 bits give you eight shades of grey (including black and white), 8 bits give you 256 shades of grey, 16 bits gives you 65,536 shades of grey, and 24 bits gives you 16,777,216 shades of grey. How many shades of grey your eye can distinguish then becomes the question. With sound, 24 bits should give you far more detail than 16 bits. Whether your ear can hear the difference I can't say. Personally I spend my money on soft foam earplugs (to protect my hearing when I'm out and about) and acoustic foam panels (to dampen echos) in my living room rather than buying expensive stereo equipment. -- Tdkehoe 16:09, 14 February 2006 (UTC)
I searched Hydrogen Audio and found 25 pages of discussions about 24-bit audio. Could you give the specific topic title? Was this someone's opinion, or a published study? I've never heard 24-bit audio but I work developing voice audio equipment using 14-bit, 16KHz chips in portable battery-powered devices, and my voice sounds great. Then I use a 16-bit, 44KHz rack-mounted processor and my voice sounds far better. That's just my voice in headphones. I have no doubt that for orchestral sound on decent speakers most people could hear a difference between 16 and 24 bits.-- Tdkehoe 16:09, 14 February 2006 (UTC)
201.231.97.156, your calculation is wrong. Higher frequencies have a much smaller amplitude than low frequencies. With every octave, you will loose 6 dB or one bit. So, if you record a signal with the frequency range of the human ear (from 20 Hz to 20 kHz), these are 10 octaves, so in a 96 dB (16 bit) recording, there are only 36 dB (6 bit) left at 20 kHz. There are also recommendations to leave some headroom of up to 23 dB, which means you will end up with only 13 dB (2 bit) at 20 kHz, which is completely insufficient. -- Sloyment ( talk) 00:54, 10 March 2013 (UTC)

Everyone - I'm going to try and re-write this article to conform to better standards and will try to address all the various issues here. Once I'm done, I'll put the article at User:Analogdemon/Drafts/DVD-Audio for everyone to see. I'll post here when it's ready and then, assuming it floats people's boat, I'll change the article itself. I hate seeing all those boxes at the top of this article.

OK, I rewrote major portions of the article (basically everything except the CPPM section because that was already very well done).
Some notes on the rewrite:
I welcome any comments. Cheers! -- Analogdemon ( talk) 16:49, 16 February 2006 (UTC)
The list of requested references follow. The list is supposed to be extensive.
Great work everyone. This article is light years ahead of where it was 12 hours ago, nevermind before I rewrote it. Thanks to everyone who offered feedback to the new article, and thanks to everyone who has made edits to improve it. This is the true spirit of Wikipedia and we all should pat ourselves on the back. Let's keep it up! -- Analogdemon ( talk) 15:20, 17 February 2006 (UTC)
I put the word "popular" back into use in the article to reference "Pet Sounds". It is widely seen by music lovers and critics alike as one of the greatest albums of all time. Q Magazine votes it the greatest of all time. Rolling Stone put it as the second best album of all time, and countless others. -- Analogdemon ( talk) 00:19, 18 February 2006 (UTC)
A reference for the amplifier interfaces was requested. Unfortunately, these things seem be to somewhat fluid at present, and much keeps changing. The citations that I had for the edit have themselves been heavily edited, and continue to be so.
Most of the problems seem to be connected to the current paranoia over unauthorised copying of disks or extracting the data for distribution by other means. Commercial interests also seem to play a part.
The 6 channel analogue interface is obvious enough, but players have been heavily critisised because, in most players, it is not possible to adjust the individual channel amplitudes or even the delay times. the only control available is a master level control.
The Firewire interface, misleadingly (for this application) referred to as DVI, has appeared on precious few players, mainly because the HDCP encryption that was supposed to protect it was broken before it was even deployed. It has appeared on even fewer amplifiers.
The SP/DIF (or TOSLINK) interface suffers from an even greater lack of information. The specifications for almost all players neglect to mention the limitations in any detail. Most will make some vague reference to the fact that individual disks may give rise to limitations on the way the disk is played. That's it - nothing more. I personally have one player that completely disables the SP/DIF output for all disks, and one player that downconverts to 48kHz/16 bit (except for disks flagged to allow the 96kHz/24 bit that they are recorded at - and I have one such disk).
The interface issue is a complete mess at the moment, and may go a long way to explain why take up of the format has been very poor. —This unsigned comment is by 20.133.0.14 ( talk • contribs) .

HDAD may be just a marketing term, but it's used consistently and referenced by third parties to mean a specific type of disc in a specific format, which is not covered in that section.. HDAD already redirects to this article, but isn't mentioned anywhere in the article itself. It should stay. Torc2 21:44, 21 March 2007 (UTC)
Has anybody in any official capacity announced they are abandoning their respective high-def formats? That's really the only definitive answer to this. Torc2 21:44, 21 March 2007 (UTC)
DVD-Audio's copy protection was overcome in 2005[6] by tools which allow data to be decrypted or converted to 6 channel .WAV files without going through lossy digital-to-analogue conversion. Previously that conversion had required expensive equipment to retain all 6 channels of audio rather than having it downmixed to stereo. In the digital method, the decryption is done by a commercial software player which has been patched to allow access to the unprotected audio. As the DVD-A format has not gained wide commercial interest or acceptance, decryption tools are still very primitive.
I don't see how reference #4 actually supports this sentence, particularly the part about 48kHz delivery via unencrypted digital:
"Whereas DVD-Video audio formats such as Dolby Digital and DTS can be sent via the player's digital output to a receiver for conversion to analogue form and distribution to speakers, DVD-Audio cannot be delivered via unencrypted digital audio link at sample rates higher than 48 kHz (i.e., ordinary DVD-Video quality) due to concerns about digital copying.[4]"

There seem to be two very useful wikipedia categories, namely: Category:Albums_released_on_DVD-Audio and Category:Albums_released_in_Super_Audio, which can be added to the bottom of individual albums. I haven't seen one for Blu-Ray music (or indeed surround albums), but still, I figure the people reading this might be in the know as to which albums are currently missiing from the categories... —Preceding unsigned comment added by 81.141.22.60 ( talk) 18:39, 24 July 2009 (UTC)
It seems like both of the categories above contain around 150 albums, which is not enough to fill the Billboard 200. DVDA is currently behind by about a dozen. If the format war is still going on, and if the number of available titles is a factor in deciding who wins, how about we see if DVDA can beat SACD to this number? —Preceding unsigned comment added by 81.141.18.238 ( talk) 19:04, 12 September 2009 (UTC)
I restored software webpage links erased by Blinksternet:
a)"These may be much welcomed links to references." is the phrase used by the Wikipedia engine when it comes to adding links. I assume that, notwithstanding the eraser's extended editing rights, this overall policy of Wikipedia's should prevail
b) There are external links in the SACD article, which, incidentally, were not erased by the same editor's review.
c) There are very few coherent and organised links on the net to the software in question.
d) The edit suppressed a link to the only available open-source software for authoring DVD-Audio discs (dvda-author, DVD audio tools project), a poor decision which seems to run against the grain of Wikipedia's philosophy.
e) I am the main admin of the above-mentioned open-source project. Should Wikipedia editors erase software links again, I will have no other option than opening an autonomous article on DVD-Audio software authoring--I'd prefer not to for obvious reasons.
f) To be fair to competitors I restored all links to commercial stuff, however I would understand if some of these commercial links were retrieved. -- Fabnicol ( talk) 11:16, 30 October 2009 (UTC) —Preceding unsigned comment added by Fabnicol ( talk • contribs) 11:11, 30 October 2009 (UTC) -- Fabnicol ( talk) 11:16, 30 October 2009 (UTC)
Concerning these tests which were "allegedly" performed where no real difference was discerned when listening to DVD-A and comparing it to a HQ mix of the same recording on a red book CD...GET REAL!
It is true that the original sound or subsequent mix engineering can make or break a completed work in either case. And to look at a poster-child example of "minimal difference" - I might submit the 1970's "Doobie Bothers" release "The Captain and Me". The original of this work is fantastic and among the finest in both its vinyl and stereo CD formats. The more-recent DVD-A multi-channel re-mix differences are "there" for sure, (especially since the 6 discrete channels (PCM) provide the spatial presence that just cannot be obtained with just 2). BUT that is the rare case for me....and actually where the buck stops.
Notice I am not trying to impress with talking about sampling rates, bits, or compression schemes - just a baptism of full and pure sound quality, dynamic range, SNR, and excellent staging.
Now for MY "Pepsi challenge": You round up that same group of "Helen Keller wanna-be audiophiles" and bring them to MY living room. I would put on just a single "old reliable": "The Eagles Hotel California". The 2 channel mix is very nice, but the multi-channel DVD-A will blow ANYONE and EVERYONE with ears away. It is the standard by which mixing should be measured to. (Please, DO TRY THIS AT HOME)!
There are others as well, but I only wanted to make a single point to combat what I perceived to be a very serious misnomer. Sadly, the vast majority of the public could care less about fidelity of sound, (as is evident in MP3, I-pod, and cell phone music popularity).
SO...(since it's ALWAYS all about the money) DVD-A and SACD are now both dried on the vine. It's sad that "the powers that be" claim to provide the HQ audio as a side order to Blu-Ray movies as the pacifier, yet this leaves a gaping hole in music formats, (one that is unlikely to be noticed at all by the masses).
That is how it is. I may not like it - but I accept it. However, PLEASE DO NOT insinuate that "there was little difference anyway". That's just ludicrous. (My 2 Cents). —Preceding unsigned comment added by 69.250.115.138 ( talk) 16:53, 30 January 2010 (UTC)

e) I am the main admin of the above-mentioned open-source project. Should Wikipedia editors erase software links again, I will have no other option than opening an autonomous article on DVD-Audio software authoring--I'd prefer not to for obvious reasons.
f) To be fair to competitors I restored all links to commercial stuff, however I would understand if some of these commercial links were retrieved. -- Fabnicol ( talk) 11:16, 30 October 2009 (UTC) —Preceding unsigned comment added by Fabnicol ( talk • contribs) 11:11, 30 October 2009 (UTC) -- Fabnicol ( talk) 11:16, 30 October 2009 (UTC)
Concerning these tests which were "allegedly" performed where no real difference was discerned when listening to DVD-A and comparing it to a HQ mix of the same recording on a red book CD...GET REAL!
It is true that the original sound or subsequent mix engineering can make or break a completed work in either case. And to look at a poster-child example of "minimal difference" - I might submit the 1970's "Doobie Bothers" release "The Captain and Me". The original of this work is fantastic and among the finest in both its vinyl and stereo CD formats. The more-recent DVD-A multi-channel re-mix differences are "there" for sure, (especially since the 6 discrete channels (PCM) provide the spatial presence that just cannot be obtained with just 2). BUT that is the rare case for me....and actually where the buck stops.
Notice I am not trying to impress with talking about sampling rates, bits, or compression schemes - just a baptism of full and pure sound quality, dynamic range, SNR, and excellent staging.
Now for MY "Pepsi challenge": You round up that same group of "Helen Keller wanna-be audiophiles" and bring them to MY living room. I would put on just a single "old reliable": "The Eagles Hotel California". The 2 channel mix is very nice, but the multi-channel DVD-A will blow ANYONE and EVERYONE with ears away. It is the standard by which mixing should be measured to. (Please, DO TRY THIS AT HOME)!
There are others as well, but I only wanted to make a single point to combat what I perceived to be a very serious misnomer. Sadly, the vast majority of the public could care less about fidelity of sound, (as is evident in MP3, I-pod, and cell phone music popularity).
SO...(since it's ALWAYS all about the money) DVD-A and SACD are now both dried on the vine. It's sad that "the powers that be" claim to provide the HQ audio as a side order to Blu-Ray movies as the pacifier, yet this leaves a gaping hole in music formats, (one that is unlikely to be noticed at all by the masses).
That is how it is. I may not like it - but I accept it. However, PLEASE DO NOT insinuate that "there was little difference anyway". That's just ludicrous. (My 2 Cents). —Preceding unsigned comment added by 69.250.115.138 ( talk) 16:53, 30 January 2010 (UTC)

@ Libfab2022:, I've been reverting non-DVD-Audio-specific additions to DVD-Audio § Sound quality. General discussion of these wider controversial points is covered at High-resolution audio § Controversy and it doesn't serve us to have it covered here too (with a potentially different slant). ~ Kvng ( talk) 16:54, 3 November 2022 (UTC)
