12/01/2008 | qawsedrf | No such thing as a DSBD from '87. | |
12/01/2008 | charlie miller | Yes, there are DSBD's in 1987. The first DSBD in the vault is 12/26/82. This whole tour was recorded digitally to PCM. | |

To further clarify things: First digital recordings in vault: PCM - 12/26/82 DAT - 12/27/87 |

If you think PCM is true digital, which it is not. Also, in the early 80's models all of the processing was done on the analog side. PCM was an engineering solution to a bit-management problem. To solve the problem, part of the signal had to be eliminated, but without degrading the sound so much that it became unacceptable to the public. Enter PCM. This ingenious electronic fiddle truncated the original bandwidth from 100,000 to 20,000 hertz, since humans cannot normally hear frequencies above 15,000 hertz, and "sampled," or took a digital snapshot, of the remaining information 44,000 times a second. This doctored data was repackaged into 16-bit packets capable of playing back a symphony in 74 minutes or less. Of course, the acoustical engineers who invented PCM knew that the condensed 16-word product would be inferior to the original: For one thing, filters, on both the encoding and decoding ends, cause audible "errors." For another, chopping out all the information between 20,000 and 100,000 Hertz reduced the harmonic depth of the music itself. |

The PCM tapes in the GD vault are digital :) Not gonna debate this with you. |
