The error correction that keeps your CDs sounding the way they're supposed to, even when scratched or dirty, is applied at a lower level. So while there isn't as much protection on an audio CD as there is on a CD-ROM, there's still enough to provide perfect or near-perfect sound quality under adverse conditions. All of the data written to a CD uses CIRC (Cross-Interleaved Reed …
CD Error Correction. Is it Audible ? | diyAudio

Error correction happens inside the decoder IC (CXD2500 in your case), there's no need to go thru several analog stages and another sampling process which might mask the effect you're trying to uncover.
Do I need "error correction" when importi… - Apple Community
https://discussions.apple.com/thread/1724901
If "error correction" is unchecked, you get a dropout every time there is an error reading a CD. Very audible and annoying! "Error correction" means that iTunes will try again to read the CD until the bit stream correctly passes the error detection checksum test. "Error correction" definitely does not degrade sound quality!

CIRC can correct nearly 4,000 consecutive erroneous bits, which is equal to about 2.5 millimeters of the track on a CD. And it can hide more than 13,000 consecutive errors, or nearly 9 millimeters.

A CD contains additional information to correct read errors to a certain level (Reed-Solomon Error Correction). But if there are too many bits which can't be read, i.e. because of scratches, there's a problem. With CD-ROMs errors are not tolerated; even 1 single bit error may render a complete database useless or cause a program to crash.

A CD-DA has two layers of error correction, followed by an error-concealment facility. What this means is that if an error occurs on the disc that is too severe for the error- correction circuit to recover the original data, the corrupt data is then passed to an error-
Why I Ripped The Same CD 300 Times - john-millikin.com

The primitive error correction codes in the CDDA standard, designed to minimize audible distortions on lightly used disks, are not capable of fully recovering the bitstream on CDs with a significant error rate. Contemporary CD ripping software works around this with two important error detection techniques: redundant reads and AccurateRip.
EAC C2 Error Correction; use it or not?
https://hydrogenaud.io/index.php?topic=7734.0
On all CD-ROM media are at least two levels of error correction, called C1 and C2. If both fail, the output is probably not correct anymore. Most drives are not able to report if audio reads failed or not, so each block had to be read twice and be compared to make sure that everything is fine.
