Need Audio CD Ripping Software Recommendations


Lord_Elrond

Recommended Posts

I have a large audio CD collection.  I am planning to re-rip my CD collection to FLAC.  I want to keep my audio playback quality as free as possible from issues such as clicks and pops due to scratched CD surfaces.   I am looking for a stable and reliable CD ripping software (either free or paid) that will allow me to copy my CDs to FLAC and offer ripping settings to handle potential audio issues due to factors such as scratched CDs.  Depending on the software that you recommend, could you also tell me which rip setting is best on that software to minimize audio issues from CD scratches?     I previously used Media Monkey for my ripping but I have had issues with the software constantly resetting my rip settings to default and it is becoming annoying.  Thanks in advance.

To offer a fuller answer to your larger issue.  Accurate Rip will tell you if there were errors compared to as many reference discs it has stored.  Inside the AR enabled program you can set parameters for handling bad frames.  Be that cancelling the download after X amount of read failures or any number of other options.  In EAC this is a simple option under "Extraction" in the options.  DbPoweramp is much more fully featured in the ways mentioned and I believe it's listed under Secure Rip settings.

 

Now what you wanted beyond that was how to handle sound glitches.  EAC offers a very simplified editor which may prove enough.  Beyond that you would need to look at dedicated software such as is used to correct digitized vinyl.  DbPoweramp has no utility for this and expresses itself through more robust, will read the disc at a glacial pace for days if needed, ripping scheme.  

 

CRC comparison on a file per file basis is what they are looking at.  If you get a low confidence rating try re-ripping that track.  If the CRC changes you know there were problems.  To further that ability you can load your entire library into Foobar and use a plugin that checks for incorrect CRC.  A few hours/days/weeks later when it finished you can delve through the log and see what failed and needs to be ripped again.

It might be worth looking at why many of us rip to WAV to use as backup copy and batch converting to flac for the working copy.  A disc image with, or without, a cue sheet has advantages.  You probably don't plan to rip your entire collection again any time soon so make sure you have thought it through.

 

Making sure you have the latest copy of flac installed in the ripping program is a good start.   ;)

You don't know real CRC value. So it is comparioson with non-exact value.

audinventory - the CRC may be non-exact but if you used accurate rip it is a non-exact value that a lot of other people agree with and if you start with a good baseline (i.e. a good rip that correlates with accurate rip) you can at least detect a change from the baseline which is a very good starting point.

For most albums CRC is a known quantity that can be checked against all the available databases as I stated. 

 

However, returning to your point, the exact value is not in contention at this juncture.  If I rip a single track five or fifty times it should yield the exact same CRC value if the digital data is uncorrupted by disc/read error.  Should it not?

100%-correct checksum S1 is checksum is calculated by original wav files that are used to produce CD.

 

At first glance, it seems that majority of checksum values (baseline) is correct.

 

But there is no 100%-warranty that the majority have correct value.

 

Because the audio data (and its checksum S2 respectively) are defined by a systems

[manufacturing errors

+ using/storing damage error

+ cd drive device error detection and correction

+ cd drive probable bugs

+ cd ripper error detection and correction

+ cd ripper probable bugs].

 

And we can't 100%-guarantee that all these different non-certified systems will calculate checksums correctly in majority of cases.

 

I.e. checksum majority with value S2 may be not equal to original checksum S1.

 

A safe CD ripper can detect errors in standalone mode. And adding database checksum S2, that is not 100%-exact, cause additional uncertainty.

Not checking with the database isn't going to improve your odds.

 

Improve. You have correct error detection probability Pripper lesser 1.0.

 

If you add checking with checksum database, the database correct error detection probability Pdb (also lesser 1.0).

 

Total correct error detection probability P = Pripper * Pdb.

 

Example (numbers are not exact):

 

Pripper = Pdb = 0.999.

 

P = 0.999 * 0.999 = 0,998 < Pripper = Pdb = 0.999

 

P is lesser Pripper and P is lesser Pdb, because numbers in right part of formula both are lesser 1.0.

 

So Total error detection probaility is improved if only 1 of mthods is used.

That's not how it works.

I'm sure you're capable of figuring that out by yourself.

I can't read your minds.

A manufacturing fault could result in every "good" rip containing the same error. Now if this is the case, you have no chance of ever getting the correct data. Getting the same as everybody else is the best you can hope for.

 

I don't disagree.  The best, OP's real world situation where a disc is producing audible and software test errors, case is retrieval of any tracks with data that wasn't corrupted by the physical damage to the disc.  Obviously the best case for a like new undamaged disc is closer to what you infer.

Assuming you're on PC, I think that dbPowerAmp is best. Incidentally, it will rip HDCD discs to 24bit/44KHz, so that's useful (some HDCD discs don't even say they are).

 

I'm not a PC person but one thing you definitely want is something that can do a good job in getting the right metadata for you. Otherwise it makes ripping a more tedious process.

The simple multiplication of probabilities suggested by Audiventory is not correct. The probability of getting a correct rip does not depend on whether or not we compare it to other rips.

There is no "probability of getting a correct rip". There is "probability of correct error detection".

It is different things.

Sigh.

 

If your CRC matches even ONE other rip, the odds against your having a bad / inaccurate rip are billions to one.  It's obvious - that's just how it works.

 

All this talk about "odds" and "possible" are just that - talk.

One other rip is local multiple re-readings of a compact disk with buffering elimination.

 

In contrast to the checksum, in local comparison (inside a safe ripper software) we:

- compare each byte identity and

- check C2 flag for each byte of each reading.

 

There many variants of statictical processing.

 

That way we can display damaged sample(s) and check it in an ordinary audio editor even.

 

Here table of detected errors and its timeline location (upper black band with coloured errors) for real CD track. In this CD 1 track is damaged. But in the audio stuff I can't see errors.

I suspect that the errors was found and fixed inside CD-drive device.

 

Sometimes ripping seances cause enough big difference of error locations at the track timeline.

Not exactly @jhwalker.  The change between offering helpful educational prodding towards someone revisiting their hard traveled CD collection on a new gaming PC to audiophile standards in the production > home reproduction chain was when the transformation from just talk occurred.  

 

No matter how unfairly the elementary description quoted was set upon as a basis for examination.  :)
