>audio CDs which I've found don't use checksums or other mechanisms to prevent small defects from mangling the bitstream Redbook audio CDs does use CIRC error correction, by storing 8 bytes of parity data inside each 33 byte F3 frame. It is not enough to correct all errors though, and Yellowbook data CDs stores extra correction codes on top of it. (276 bytes for each 2352 byte sector). (and there's also issue below F3 frame level about EFM modulation, whether merging codes are generated properly to keep DSV low enough) See: https://byuu.net/compact-discs/structure/ https://byuu.net/compact-discs/structure/ https://john-millikin.com/%F0%9F%A4%94/why-i-ripped-the-same-cd-300-times https://john-millikin.com/%F0%9F%A4%94/why-i-ripped-the-same... https://john-millikin.com/%F0%9F%A4%94/error-beneath-the-wavs https://john-millikin.com/%F0%9F%A4%94/error-beneath-the-wav...
