AV Education on RHT Part I: All About The Making of a DVD-Audio Disc Written by Mark Waldrep, Ph.D. Background Readers
of online publications like Audio Video Revolution often read reviews
and comments regarding new releases on both SACD and DVD-Audio, the new
multi-channel, high-resolution audio formats. There’s always the
obligatory listing of tracks and a discussion of the sonic quality of
each title and a breakdown of the features included on each disc, but
rarely do consumers get details on the production procedures and
challenges that go into producing a title in these new formats. It
might be nice to know the recording process involved (analog vs.
digital stages), the number of mixing choices made during a production
and the depth of bonus materials that will be included on a disc. Well,
as the producer of many DVD-Audio titles for my own audiophile label,
AIX Records, and owner of a production facility that services the DVD
production needs of other labels (Rhino, Sanctuary and Savoy Jazz, for
example), I thought it might be interesting to explain and discuss the
production realities behind a few DVD-Audio titles. The plan is to
break down the process into three distinct phases: the pre-production
planning, the actual recording, mixing and mastering, and the
multimedia development/DVD authoring. This process is also relevant to
other new technologies like DualDisc as well as music oriented Blu-Ray
or HD-DVD discs but please note none of those formats are currently on
store shelves quite yet.
In the interest of complete disclosure and fairness, I should state right out front that my personal preference in the “format war between SACD and DVD-Audio” skews in favor of high-resolution PCM over DSD. Let me share a few of my reasons for this choice. First and foremost is the fidelity of the sound delivered to our customers. While both formats have the potential to deliver audio fidelity that surpasses CDs, comments that I regularly receive from customers and the reviews that I read put our tracks at or near the top of most lists (we recently took Number One and Two in the list of the Top 20 “best multi-channel discs” in the May/June issue of DVD Etc. Magazine). Secondly, AIX Records has been producing multi-channel, high-resolution digital audio for many years and has developed a rather extensive capability for dealing with multi-track PCM audio. All other things being equal, the number of equivalent tools in the world of DSD is not yet as great. In fact, a large percentage of so-called DSD tracks actually existed at some point in their life as PCM. When I started making our products, the best available DSD system, the Sonoma from Sony, could record only eight tracks and all post processing had to be done in the analog domain, so going with PCM was a no-brainer. Thirdly, as any current AIX Records customer will attest, I am a strong advocate of delivering feature-rich discs to consumers. This means having video, photos, lyrics and much more on the same disc that plays the new high-resolution, multi-channel audio. As most of you are already aware, DVD-Audio discs usually contain a “DVD-Video” zone. Producers of DVD-Audio titles can choose to place Dolby Digital or DTS mixes in that portion of the disc for playability in DVD-Video machines, as well as video footage. SACDs are audio-only products; there is no provision for multimedia. The final reason why I chose to release titles in the DVD-Audio format instead of SACD is the vast number of players that can access the audio and video that we put on each disc. Currently, there are over 75 million DVD-Video players and 3.5 million DVD-Audio players (including factory installed car systems), compared to more than a million SACD players reportedly installed in the U.S. Don’t get me wrong, SACD can sound very good, especially for stereo music, but as a professional recording engineer and the owner of a specialty record label, I prefer to make and sell DVD-Audio titles. I
founded AIX Records in the spring of 2001 because I wanted to explore
the emerging DVD-Audio format with music content that I would produce
and own. Back in the spring of 1997, AIX Media Group was the first
company to produce and commercially release a DVD-Video title. Yes, we
had 100 percent of the DVD business for five days back in March of that
year. Since then, we’ve produced many hundreds of DVDs for movie
studios large and small and have maintained a healthy production
company in the intervening years. The arrival of the DVD-Audio format
offered an opportunity to produce AND own content. Since the cost of
making an audio title pales in comparison to producing a feature film,
since we have tremendous expertise in audio/music and since I’m an
audio engineer/musician, the world of DVD-Audio seemed the right place
to start a new venture. |
