Detect audio noise from scratched CDs
 

Whenever a CD is scratched or damaged, you would hear pops and noises that are obviously not part of the music.

Sometimes a CD is scratched even a little bit, is there a program that detects any minor distortion or flaw?

Thanks

Usually interpolation covers small scratches very well.

Yes, you need a program with handling of C1 and C2 errors. EAC (exact audio copy) can do that for you.

Also most high quality CD transport units will output these errors on their interface (this is important when measuring digital audio quality and jitter with these units).

I am not familiar with the terminologies you used.

Before I backup my Audio CD, I can run it through a program, you mentioned EAC, and dtermine if the original copy was clean or not?

Then look them up. Wikipedia and Co. were not invented just for fun.

You can do that and later on use some other tool to rip the data - but I really don't recommend any other program then EAC for ripping digital audio data from CD.
Because I assume you're using a MS operating system there is really no other choice for a ripping tool (and don't mention CDex, the engine can't be compared to the one in EAC).
