[somewhat ot] Importing Audio from CD

Greetings maxers,

This is somewhat off topic, as it isn’t a 100% max specific query, so
let me apologize in advance…. However, i know folks here know their
stuff when it comes to digital audio and i am desperate for an answer.

I always ask folks who send me audio files to work with, to send them
as data because i have noticed that when you rip from an audio CD
using iTunes you sometimes get drop outs even if you have the:

[Use error correction when reading Audio CDs]

option checked off in Preferences –> Advanced

Now i have some Audio CDs that i need to integrate into an archive
(the data is gone and all i have are the audio cds to work with) and
i have to be absolutely 100% certain that i have yanked all of the
audio off the CD w/o dropouts or any other data loss…

I am not at all sure how to do this…

The only thing i can think of is to rip the audio several times and
compare it and if it is the same then (under the crazy assumption
that the rip would not drop data in the same place twice) …. but
then i have to rip it several times which would take a LOT of time
and a LOT of disk space… and then of course i would have to compare
the soundfiles while ignoring the header … ugh.. and the only way i
can think to do this is to load both soundfiles in to a DAW, invert
the phase of one and mix…. and then do an amp plot and check that
each sample has summed to 0. … you can see why i don’t want to do
this as i have dozens of CDs to archive….

so is there any fail-safe way to yank audio from CDs?

I am on a Mac, intel… os 10.4… I indeed have Max and Peak and
Garbage band (i guess)….

Any help would be greatly appreciated…

cheers,

kevin

Short answer; don’t use iTunes.

Andreas,

I already know the short answer…. That iTunes sux and is not a secure
rip utility is already old news to me…

i am looking for the longer answer…

For example there is cdda2wav on the command line for some flavors of
Unix and also cdparanoia for linux, but i don’t see any binaries for
MacOS X and not sure if they have been/can be built without something
like fink or darwin ports… etc..

under the hood, wouldn’t this just do the same thing (as in use the
same slurping utility) as iTunes does?

I wonder about Peak too…. it used to be terrible at importing CDs
in the old days.. I will
try it as i have and use peak 5.x …. forgot all about peak’s
importing abilities…. hmm…

Filemerge.app …

look in :

/Developer/Applications/Utilities/

and you will see an old friend ….

hehe you are as old as me… [that would be very old]

Rocking!

That’s just what the doctor ordered.. it reads from the disk multiple
times and does comparisons, etc, and uses
the CD paranoia thing as well as it’s own error checking…

Bravo~ woo….

Thank you thank you thank you…

Do it with Max! No, not that one, this one:

Damn useful little (Freeware) conversion utility with excellent CD ripping
features,
Cheers

If you check the error correction to on!!! iTunes is doing that for you.

If there is an error, it will read again, till there is no error. after
several tries it will interpolate, which still sounds ok…

You can tell the quality of the CD by the speed its ripping. The slower
the worse…

I used to use the ripper from Toast in OS 9, which had a special feature
for that… I guess that’s not an option…
