They seem always there. They're not *loud* clicks, rather a quiet but very-often repeated sound. This, in fact, may be simple clipping. Except that I'm not ready at this point to think that the Chandos company would simply release a crappy recording; copy protection seems more likely. > Just to be sure, have you tried the CD on a normal CD player? Do you > hear the clicks then? I have not yet tried. This is probably what I need to do next, as this seems to be the only way to find out if this is actually copy protection - or mere clipping. (Or perhaps I can somehow check for clipping by looking at the waveform in something like Audacity?)
