Yardbird,

Pardon me for jumping in, but I think your problem is that you're misunderstanding what Kevin is telling you. correct me if I'm wrong, Kevin, but my understanding is that the intermediate stage of writing an image file to disk is NOT intended to correct/prevent errors that result from flaws on the source disk. Rather, it is intended to provide an opportunity to correct errors that were introduced in the transcription process, from source to destination, before these errors get permanently written to CD, thus producing an expensive coaster. Do I have it right, Kevin.

Blessed Be,

Dana

What I'm asking is, how does the intermediate stage of having this image
written to disk improve accuracy?  that is all I've been trying to ask by
what I've said. If the music CD from which you're ripping tracks has flaws
that would distort the sound or introduce noises (I don't believe you mean
the pops and clicks that plague LPs, really, do you?), then how does this
intermediate step help protect against winding up with a noisy .mp3 file? I
don't know what you mean by asking rhetorircally why the developer would
include this stage as an option. I honestly don't know what's accomplished with this. If it doesn't give the program a chance to clean up errors, then
what good does it do?  I am *not* speaking sarcastically.  I'm really
asking.being

Do you think I'm questioning the wisdom of the program writers who include
this option?  No, not at all.  I'm not anywhere near being able to address
something like that.  I honestly just don't see how making an intermediate
copy is going to prevent you from getting bad sound from a damaged CD.  I
mean, what is done along the way to remedy a bad CD? You're saying nothing is done? Do you see what I'm not getting? I don't know how else to phrase
it.

No Joel.

Once an image is created it's not going to be able to go back and clean up
any imperfections. My point is that the creation of the image itself allows
the ripper to separate the processes.  If you're ripping on the fly you
won't get an image file at all because the encoding is being done on the
data stream as it leaves the CD-ROM.

You really only need ask yourself a very simple question as to whether you
want to use on the fly or not.  Do you think that developers put this flag
in just to slow you down when ripping or burning?  The developer obviously
wants their program to rip and burn at the maximum speed and quality so why would they build in a feature who's only purpose would be to slow you down?

It's pretty obvious I think that the trade off is that you forgo some
quality for speed and so it's really a personal choice.

Kevin,

You mean that when you have flaws on an audio CD, once they get written to
an image file on disc, the encoding process is less likely to pick up the
flaws, somehow, as it creates the compressed file?

Hi Daniel.

It's not that flaws at source can be fixed just because you've unchecked
the
"on the fly" checkbox.  If there are flaws on the CD then they will cause
issues whether you rip on the fly or not.

The point I'm not making very well is that by breaking down a complex
process involving the extraction and conversion of data from a spinning
disc, there are less chances of issues arising if the process is instead
broken down into a number of discreet steps. Specifically, separating the
process of reading the disc to extract all audio information before any
conversion to MP3 is done using an encoder that is applying complex
algorithms to the data to assess what it thinks can be disregarded and
what
it thinks needs to be retained to fulfil high quality sound reproduction.

Hope that's clearer.

Kevin
