Hi Guy's,

Is there any way either in MC or third party that can scan all my music files and let me know if they are corrupt or possibly corrupt.

I ripped a lot of my discs with MC in secure and they are 100% OK however some of my discs were ripped on my Home Server with My Movies and I am now finding while listening to them that some have pops and clicks and others sound like the CD skipping.

Short of listening to every CD I would like to scan them for possible corruption so I can narrow it down.

Thanks.

John

If you use APE, you can run a verify with Monkey's Audio.

I think there are FLAC tools available as well.

And keep in mind the pops or skips could also be related to the audio playback.  Does it always skip in the same spot?

Thanks Matt,

The files are a mixture of FLAC and WMA. It does skip at the same point and sounds like it might have been a miss rip.

I don't think any application can detect ripping errors that are included in the ripped source wave signal. Technically the encoded files are correct.

As far as I know, the only way to find such errors with software is to compare the files with other, correctly ripped files.

Perhaps you should just re-rip the "unsecurely" ripped CDs using MC's secure mode. Can you differentiate them (for example, maybe you saved MC's secure rip logs) and are you speaking about tens, hundreds or thousands of CDs?

Some ideas:

Check tags for the files ripped with My Movies to see if there is a unique tag written by My Movies.  Something that you can use to identify the files ripped by My Movies from the files ripped by MC.  Maybe a unique compression setting or compression level?  Maybe just a particular tag?  You can have MC display all the raw tags for a file.  Or you can open the file in MP3Tag and look at what MP3Tag calls extended tags.  That will show all tag info.

Another idea that may or may not work.  There are programs for declicking and identifying clicks.  The programs are used by people doing digital recording of vinyl records.  The programs can detect clicks and pops and other unwanted vinyl noise.  Maybe one of those programs might detect the click from a bad rip.  Just maybe.  It's a different kind of click than a vinyl click.  It might be detected or might not.  If one of those kinds of programs could be run in a batch mode and log any clicks it finds then you might be able to go through your collection and identify the bad rips.  I don't know of a declicker program to suggest that would fit those needs.  It would require some hunting and searching.

Thanks guys for all your suggestions.

I do have over 20,000 tracks so will take a wee while to go through them. I will look at the tags to see if MyMovies has tagged them with something I can use to identify them. As I said, I normally use MC with secure rip however I did cheat and used a Dacal 100 disc auto loader and MyMovies on my Home Server to rip a few batches.

Might be the perfect opportunity to listen to all my old music again for the purpose of quality control mind LOL

...adding to Frobozz's suggestion, once you identify something unique, note that you can probably make an smartlist to automate collection of said tracks.
