De standaard voor audio CD's nu (74,xx minuten, 16bit/44,1kHz) is dacht ik de zg. Redbook audio standaard (ik weet niet helemaal zeker meer of dit klopt), en er bestaan ook standaards als de Orangebook en de Yellowbook standaard, maar de verschillen ken ik niet.
Die "kleurtjes" zijn afgeleid van de kaft die rond de officiële publicaties zat...
Er bestaat nog een ander bekend rood boekje natuurlijk: dat van de Chinese communistische leider Mao...
