Blu-spec CD2 arrives

Political Correctness...defined

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

No, I haven't as there's nothing in the current selection that interests me.

They play on your standard CD player. Apparently, the burning process results in 50% less distortion.

Sounds interesting. For around $25.00 I'll give one a try. I do classical.

Hey Snoop- here are 2 good ones! :D (at least I think they are....) If you get one- I would like to know what you think.

Vivaldi: The Four Seasons, etc. [Blu-spec CD2]

Holst: The Planets [Blu-spec CD2]

Re: Blu-spec CD2 arrives

Ordered the Pavorotti - IN CONCERT which I wanted anyway and the James Galway which I already have to compare. They are two of my favorites.

Thanks Jessie.

I don't understand it. Help.

I have some of those Japan 24 bit CDs, but I guess not like these. The deal in the past is that due to space on a CD, not all tunes can be included.

I have SACD and DVD. On a CD, there is less space.

For example, I buy digital from HDTracks. I like them. You can't copy one to a standard CD as the file is too big.

I don't understand this, but expect it to be good as I am an optimist.
Can anyone explain how they will put a 24 bit album on a CD?

Re: Blu-spec CD2 arrives

I would assume it uses different error correction- CIRC

The smallest entity in a CD is called a channel-data frame, which consists of 33 bytes and contains six complete 16-bit stereo samples (two bytes × two channels × six samples = 24 bytes). The other nine bytes consist of eight CIRC error-correction bytes and one subcode byte, used for control and display. Each byte is translated into a 14-bit word using eight-to-fourteen modulation, which alternates with three-bit merging words. In total there are 33 × (14 + 3) = 561 bits. A 27-bit unique synchronization word is added, so that the number of bits in a frame totals 588 (which are decoded to only 192 bits music (the 24 bytes mentioned above)).
These 588-bit channel-data frames are in turn grouped into a larger structure, confusingly dubbed frame in the Red Book audio CD's timecode-based addressing system. In CD-ROM and related technology, including Digital Audio Extraction (DAE, or ripping of audio CDs), the same structure is called a sector and is addressed with simple, sequential, non-negative integer numbers. Regardless of which name is used, each of these structures contains 98 channel-data frames, totaling 98 × 24 = 2352 bytes of music. The CD is played at a speed of 75 frames (or sectors) per second, which results in 176,400 bytes per second. Divided by two channels and two bytes per sample, this results in a sample rate of 44,100 samples per second.
