Hi - hope you can all help. I've had a run of glass-mastered CDs made and they've just come back with this fault. These were of course replicated from a glass master, not just bulk-copied in a burner, and they have a really odd distortion which sounds a bit like an old dusty LP in the first few tracks, but the distortion / noise gets more noticeable as you go higher up the track numbers, and the final track is really, really bad. Track 1 has a bit of noise, but almost unnoticeable, track 28 is absolutely horrible. It sounds like an LP when you have grunge on the stylus. This is an extract from track 17 (which is about 2/3 of the way through - the CD has 28 tracks in total.

Anyone know about CD replication from a glass master? Before I get back to the company!!
