AB  - Many audio CDs (mostly CD-Rs but also CD-ROMs) have defects that appear due to bad manufacturing, careless use, or simple aging of its physical constituents. Here, we study such audio CDs that are still readable with a standard player (computer CD/DVD drive or standalone audio player with digital output), but whose defects are not fully handled by error correction codes, resulting in a highly distorted signal. This study is two-fold: first, we characterize these errors on a few example discs, and second, we study different means to restore the audio content, by fusion of multiple reads and by the use of interpolation schemes.
