Do CD-R's sound the same as originals

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.

In any case, I have direct experience with minor read errors WHICH DO INDEED pass through to the write process, when producing an audio CD-R, and that was at 1x speed both ways. Most everyone in the computer field reads and writes data CD-R's at least at 4x speed, and usually higher, and the data gets transferred and then recorded WITH ABSOLUTELY NO ERRORS. It doesn't matter to me where the interpolation occurs, it's just that it DOES occur, so in my view and experience, you CANNOT compare the process of reading and writing a Data CD-R, with that of reading and writing an Audio CD-R. The nature of CD audio, is that EVEN SMALL ERRORS DO INDEED "GET THROUGH", and everyone in the recording industry who's involved in the production process knows this all too well.

With up-to-date software and hardware, it is easy to prove to yourself that bit-perfect copies are being made when using a computer CDR setup - there are many programs to grab "files" of data off an audio CD and compare them to files grabbed off other audio CDs. Occassionally the copying software reports an error and won't finish the job, but every copy I've ever compared to the original matches perfectly. I sold my Phillips CD copier/recorder, so I can't do the comparison on copies it made for bit-perfect correctness. To the extent that they are bit-perfect and any difference is in jitter induced by the reflective properties of the media, I can't wait for networked components so the perfect copies can be delivered anywhere for playback. It is also annoying to think that a multi-thousand $$ transport can't retrieve data off a CDR as well as a $69 CD drive for a computer.
