Error Correction for iTunes?
My interest in knowing is maintaining the highest quality and most accurate iTunes library possible.

Don Hurter asks what "Use error correction when reading Audio CDs" does.
Audio CDs have error correction codes on the disc, so that errors (like manufacturing defects, scratches, fingerprints, and even some copy protection schemes) can often be played through without corrupting the sound.
When you rip a CD, the computer reads the raw audio data from the disc. Typically, it just reads the audio samples and ignores the error-correction codes, assuming that the data will be good. This means that if there are any errors on the disc, those errors will become defects in the sound (typically heard as pops or clicks.)
When you turn on the "use error correction" feature, iTunes will process the error correcting codes along with the audio samples, using them to correct any errors it finds. If your computer is fast enough (relative to the drive's audio-extraction speed), you won't notice a slowdown (but you may notice an increase in CPU usage.) If the computer is not that fast, using error correction will slow down the ripping.

what are those audio samples they are comparing and where are they coming from.
