What sorts of "data errors" can creep into digital musicreleases (CD/DVD/MP3/et al.) *and* what protections dothe players of same use to protect equipment and hearing?E.g., drop a tonearm and you'll get one helluva THUMP.With digital representations, there are more possibilities(e.g., introducing DC to the signal).Do players (CD/DVD/software) just assume the signal isintact? Or, do they examine it and take precautionswhen they sense something out-of-band (besides justa bandpass filter)?If they *do* act, are they smart enough to try to recover?Only to stumble on another defect moments later?Or, do they give up on the title (or entire medium) andlet the listener sort things out?[Yes, I know commercial CDs take pains to compensate forscratches, etc. But, those physical issues disappear whenyou're streaming audio or playing from a containerizedformat]
