Uh, but the two states are not (rpt not) accurately decoded. Not completely accurately, anyway. That’s why the Green Pen, painting CD tray and CD Treatments and vibration isolation and vibration control improve the sound.
Sorry, not true. CDs include error correction encoding and decoding to ensure that the 1s and 0s are accurately read. Green pens and anti vibration tweaks on CDs and players are a complete waste of time and money.
