We are very excited that Japan audio magazine Stereo Sound #169 has a news section introductory of our upcoming "Audiophile Jazz Prologue - Part 3 Limited Edition". It mentioned the 2 disc packages with Premium Made CD-R and DVD-ROM DATA with 24bit/96kHz & 24bit/192kHz AIFF files.
Thank you very much Hitoshi from FineSource.
It will hit the street on Jan 10 after our public announcement in CES 2009 Las Vegas. Again I have to mention this Limited Edition will not be re-created since it is too time consuming. Very unique CD-R with individually tested report and high resolution files for computer or hard disk playback.
Our first good news, we finally received our DVD-ROM from replication plant! The "Audiophile Jazz Prologue - Part 03 Limited Edition" package includes a "Premium Made CD-R" and this "High Resolution Files Disc".
High Resolution Files Disc is a double layer (DVD9) DVD-ROM DATA disc. It contains computer binary files. This disc is not playable by CD-Player and DVD-Player. If you want to playback on those players, the "Premium Made CD-R" which is included on the package is created for this aspect.
High Resolution Files Disc contains 4 folders:
(1) 24bit/192kHz folder: (2) 24bit/96kHz folder:
(3) AJP-03 LE - 16bit/44,1kHz folder:
(4) AJP-03 LE - Graphics folder: Booklets, Cover, Poster in PDF format.
As you can see, we provide all 13 songs in 3 different resolution standard. The 16/44.1kHz (same as CD), 24/96 and 24/192 resolution AIFF are stored on a single double layer DVD. These files are clone from our masters, that means it is bit transparent to what we created originally with our recording. We use standard AIFF file standard because it can be easily embedded album cover artwork and song info, once you copied these files to your hard disk player, HTPC, iTunes etc, the album art and info is automatically shown. No extra work is needed.
Why we provide both 24/96 & 24/192?
If we provide only 24/192kHz files, majority people who cannot playback in this sampling rate will need to use a SRC (sample rate converter). This will pollute our master sounding. On the other hand, If we only provide 24/96kHz, there are people who can playback 24/192kHz (such as Weiss DAC2/Minerva) will also use an extra SRC for up-sampling, this may also pollute our master sound with inferior SRC program/device. Therefore we decided to provide both standards.
Another reason to provide 3 resolution standards is audiophile can compare their differences and pick the one that fits them the most. The 16bit/44.1kHz is useful if you want to import to your iPOD or iPhone to listen on road.
OKay, we are not scientist. At the end it is based on our music quality, selection and sonic quality to gain our client base. We provide 2 free samples of this album for people who never hear from us on AJP-Part 01 CD & AJP-Part 02 SACD. The free samples are not compromise on quality, we provide you the highest resolution 24/96 & 24/192 for download as well.
This is used in measuring the error rate when extracting data frames from a Compact Disc (CD).
There are 3 important data: C1, C2 and CU
A good CD-R copies can create lower BLER than replicated CD. For past many years, we have submitted CD-R reference for hifi magazine preview before the actually replicated CDs are ready to delivery. We got some feedbacks that our CD-R reference sounds better than the final replicated disc. Some distributors suggested we make CD-R copies for sale. We rejected this idea for many years because it is very hard to maintain CD-R quality without testing everyone of them individually, plus the production cost will be many times higher than replicated CD.
In CD Mastering, the replication plant rejects CD Master which C1 Avg/Sec over 220, or with any C2 or CU. This is the industry standard.
Although CD-R can create lower BLER than replicated CD. CD-R is not a great media for large replication because it is not as stable as regular CD. Every created CD-R copy has different BLER, even they came from the same manufacturer, same batch.
For a large quantity CD-R production, there are usual to have some very high BLER disc. (lower graph). From the graph, green lines indicate C1 error, which is fine in most cases. The blue lines indiciate C2 error, and red lines indicates CU error. The worse BLER, the higher demand of CD transport reading.
** Now you know why some CD-R duplicated copies cannot be played in some CD player. Besides the compatibility of the player, it is also due to the non-stable quality of CD-R media. **
Audiophile Jazz Prologue - Part 03 Limited Edition
Premium Made CD-R.
We import this CD-R media directly from Japan by ourselves. They are not available in HK/Taiwan due to very high cost.
We are not using a multi CD-R duplicator. We create each disc one by one in low speed burner.
We individually measure each “Premium Made CD-R” product and generate the report. (upper graph) This is an example of our SN0076 report: Avg/Sec 0.3 C1, 0 C2 and 0 CU. This is a GREAT performance.
In our current 1250pc production, we rejected over 180 copies that failed on our test. (lower graph). They maybe playable but we want to maintain the highest standard. These 180 copies will not be sold.
We believe no one in the market has done such thing because it takes too long to create each "Premium Made CD-R" and very high costs. In Audiophile Jazz Prologue - Part 03 Limited Edition, we bundle this "Premium Made CD-R" with a double layer DVD-Rom data disc, which contains all master AIFF files in 24bit/192kHz, 24bit/96kHz and 16bit/44.1kHz resolution.
Every Audiophile Jazz Prologue - Part 03 Limited Edition package includes the unique printed report (upper graph) that matches with the serial number on each "Premium Made CD-R" copy.
