However, copying a digital file itself incurs no generation loss—the copied file is identical to the original, provided a perfect copying channel is used. Some digital transforms are reversible, while some are not. Lossless compression is, by definition, fully reversible, while lossy compression throws away some data which cannot be restored.
Also, quantization noise can be "hidden" where they would be masked by more prominent sounds. With low compression, a conservative psy-model is used with small block sizes. When the psychoacoustic model is inaccurate, when the transform block size is restrained, or when aggressive compression is used, this may result in compression artifacts.
Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector. Image noise is an undesirable ...

If CD ripper software (or other software, such as a real-time effects program, that reads digital audio from the disc in the same way as a CD ripper) were to subsequently access the music tracks on the CD, XCP would substitute white noise for the audio on the disc.
