Do CD-R's sound the same as originals

Sorry, but you surely misinterpreted your brother's words. The physical CD-ROM format, IEC 10149, has more error correction levels especially because of the fact that a single, logically irreparable error is fatal to software. CD-ROM error correction definitely does not allow for interpolated data.

Except it's mostly correct. When modems transfer data they do simple error detection/correction like the (11,8) method mentioned above. If there is an unrecoverable error, the word is resent. I wonder if data roms will also rescan a disc when an unrecoverable error is detected while the transport in an audio CD will simply interpolate. Just a thought. This came up in a previous thread and someone actually did some experiments with strait digital dumps. It was interesting and highly (in my mind) unexpected.

Dshin answers my question as I make my post... Still wondering if audio cd's could theoretically use the same IEEE standards for ripping the bits and then buffering the data for output into the DAC. Actually, doesn't Levinson do something like this?

My brother believes that the data is RE-SENT (when an unrecoverable error is detected) during the writing process for a data CD-R, and NOT done so during the writing of an audio CD-R. SORRY, but you surely misinterpreted what you think you might have learned thusfar, Dshin.

Carl, I think that you're somewhat talking past Dshin. He objected to the ---- data CD has much higher tolerance for errors than an audio CD, because of the nature of the error correction of the software (it does perform heavy interpolation to correct for errors...no personal computer would function at all, if this weren't the case) ---- which he seemed to intereprate as you claiming that data PC's do interpolation of data in the read process. His only point was that data roms never interpolate data in the read process. I think.
