Digital-Inn - View Single Post - @Andre Wiethoff and who feels to have a say on offsets.

IpseDixit · 20-11-2006

I've talked to Rich Wall, at DCA (Doug Carson and Associates),
THE optical disc encoder company (www.dcainc.com),
he allowed me to disclose about the offset experiment:
he prepared a DDP file (Disc Descriptor Protocol) for me
where 1st byte of 00: 02.00 was !00 and encoded it
in a MIS VIII encoder (http://www.dcainc.com/products/MIS/MIS_V8/),
then captured signal from LBR (Laser Beam Recorder) into a bitstream
in a raw reading file, discovering encoder places main channel's 1st byte
aligned into channel frame 00: 02.00, then came genial Mr. Sidney Cadot
(http://ch.tudelft.nl/~sidney/) with his FPGA audio readout system
(http://club.cdfreaks.com/showthread.php?t=111913 ), made with an
old drive which precisely returns such !00 when asked for 00:02.00,
Then I concluded when I saw such drive in Wiethoff's database having
a +30 samples offset correction.
