The resulting wav files had the spikes I described in my previous mail, and they sounded just like that. Clicks every several seconds. I smoothed out those spikes, and voila. Opening the wav files in a soundfile editor showed the spikes caused by the copy-protection very obviously obvious. Under Windows, playing from CD-Rom meant playing the compressed files from the data track, with the player from the data track. This sounded notably worse than the (corrected) wave files. Like badly encoded 128 bit mp3. > I'm just starting to think that what I have is after all a > problematic recording, not copy protection. At least, no data track > seems to be there (at least Linux does not mount it). I don't think this is related. The CD I talk about happened to provide this data track as a "solution" for people to be able to play the copy-protected cd on a windows PC. There might very well be CD's with the same copy-protection and without the data track. Maarten
