Static 'blips' on original cd - is this normal?

post #1 of 7
Thread Starter 
Hi all,

I am a complete newbie and novice to this so please forgive my ignorance.

I have recently converted my entire cd collection into a lossless format which was a mammoth task! Having purchased some over ear headphones, I noticed that a fair few tracks have 'grain' or 'static' blips in them, not all the way through, just in certain areas.

Assuming it was the rip, I tried re-ripping those particular tracks at lower speeds but to no avail. I then listened to the original cd on my pc and hi-fi and noticed that the static was still there!

My question is, have I just been unlucky and picked up a few duff CD's, or is it common for the original cd recording to have flaws?

Again I am a novice to this so please be gentle smily_headphones1.gif

Thanks all,
JonnyH

More than likely, you may have picked up a few duff cd's, or they need a damn good clean.

Some digital players will produce some errors in playing when there is dust, or even finger prints on the surface.

It depends entirely on the player, with some having better correction than others.

 

If you clean the discs, and they still have a problem, and the problem arises at the same point, I would conclude that the error comes from the pressing of your CD.

That said, CD's can have a huge manufacturing flaw, or something that just wasn't picked up upon, on release.

Thank you for your reply m-k,

Assuming it is a flawed disc then as I have tried cleaning it, ripping at different speeds, and also using accuraterip with c2 correction, but the static and blip are in the exact same spot. I've held the disc up to a light and cannot see a mark on it.

Oddly enough, the accuraterip confidence number for one of the CDs is 60! I thought the idea of accuraterip was to end up with a near perfect rip when the disc is present in the database and the confidence number is high? Or am I being a complete novice again?

KR,

Yes , has anyone heard "Sade the ultimate collection 2011" 

1) too darn loud (0 dynamic range)

2) some tracks were messed up, i even thought it was my headphone or pc , but if the read the reviews, all have the same problem especially with the specific tracks i experienced

The confidence number will probably work the same as Exact Audio Copy that I use to rate the rip.

 

If the CD wasn't great to begin with, it may explain the low number, but if it has matched up with the checksums of the disc written upon it, it should be 100% or as close to it as possible.

That leads me to think your player is having issues reading the disc for some reason or other.

 

Can you try in another PC, or play it on another drive to check for the blips?

I have tried it in two other players and it happens in the same spot.

I know someone else who has the album so I will see if he has the same issue with his copy.

It makes me wonder if any other tracks are impacted on other albums I have ripped frown.gif

Is it worth purchasing a cd repair kit or are they a waste of money?

If you have an accurate rip, the problem is in the CD master. There is nothing you can do to fix it. It is probably an imperfection in the analog tape used to master the CD.
