Description of disc:
HDAD 2011 - The Alan Parson Project - "Eye in the Sky". Transferred from the original 2 track analog master tapes provided by Alan Parsons this title, recorded at Abbey Road Studios, offers a sonic treat which is characteristic of Parson's work both as an engineer and as a musician. Songs such as the title track, "Children of the Moon", "Psychobable" and "Step by Step" among others ring out with a never before heard clarity showing Parsons as the master of sound he has always been. This is a work of art and will push a modern stereo system to its limits trying to reproduce all that was originally laid down on each track. A sonic and musical tour de force!

Description of technology:



The Classic Hybrid DVD Audio Disc (HDAD) is a two-sided DVD disc with 24/192 PCM data playable on DVD Audio players on one side, and 24/96 PCM data playable on DVD Video players on the other side. The Classic HDAD is a truly universal DVD disc playable on all DVD players. So if you have a DVD video player, you can play the DVD Video side of the HDAD-insert the disc with the Blue center ring facing up and enjoy 24/96 playback resolution. On a DVD Audio player, simply flip the disc over with the Red ring facing up and enjoy 24/192 playback resolution.

The process starts with the encoding of an analog signal from a live microphone feed or more commonly from an analog master tape. A highly sophisticated Analog to Digital converter (A to D) samples the analog signal 192,000 times per second (192 kHz) and assigns a numerical value to each sample point. The 192 KHz sampling rate is more than four times the 44,100 (44.1 kHz) sampling rate used on standard CDs. Through a process called downsampling, the 192 KHz data is used to derive a 96 KHz data set that is used on the DVD video player side of the HDAD. The numerical value assigned to each sample point at 192 kHz-about every 5.2 microseconds-is stored as a 24-bit digital word. The significance of a 24-bit digital word is that there are 16.8 million different potential values for each 24-bit word! By contrast, there are only 65,536 different potential values for a 16-bit digital word on a normal CD. The additional 8 bits on an HDAD allow for over 16 million additional voltage values to represent the original analog signal. Further, 24-bit resolution offers 144dB of dynamic range from the softest to the loudest musical note. At 144dB of dynamic range, we greatly exceed the dynamic range available on the world’s finest analog tape machines. For the first time in the history of digital audio, we can provide Master Tape Sound (MTS)TM. We hope that you will appreciate the effort that goes into making this remarkable HDAD when you listen to what this technological wonder has to offer.

Что было и что получилось:
Исходный материал - двухСТОРОННИЙ (не путать с двухСЛОЙНЫЙ) диск. Одна сторона представляет собой DVD-Audio диск со звуком 24/192 и играется только на плеерах поддерживающих воспроизведение DVD-Audio дисков (ну и на компе естественно). Вторая сторона - стандартный DVD-Video со звуком 24/96 играется на всех ДВД плеерах. Почему сделано на двух сторонах? Не имею никакого понятия DVD-Audio сторона просто скопирована на хард, так как нет никакой защиты на диске. DVD-Video сторона порипана DVD Decrypter и представляет собой стандартный Video_TS. Всё это влезает на обычную ДВД5 болванку. Рекомендуется записывать диск с помощью Padus DiscJuggler, простым добавлением обоих папок в проект, так как в этом случае, на 99% гарантируется работоспособность диска, как на компьютере, так и на стационарных проигрывателях.
