What am I hearing???

~~~~Hello,
I hope someone can explain why on some cd's the long piano notes sound slightly warbled. Not the normal vibration from the piano's wires. Am I hearing laser trying to track info on a non-concentric disc? I noticed a lot of cd's data area slightly non-concentric to edge of disc. Shouldn't the laser be able to trace imperfections? Warranty time? Starting to bug me, RATS!

The most probable explanation is that you are listening to CDs originally recorded to analogue tape, and what you're hearing is the speed variation of that tape.

Things it is definitely not:
--non-concentric CDs
--laser problems
--"time-smearing" of cables
--transport "wow"

None of those things can cause the effect you are hearing.

Calanctus: Well, given that those posters all gave *different* explanations for time smear, which of them sounded convincing to you?

Given that this is a problem with only some disks, the source of the problem is almost certainly the disks themselves. I'd hate to see this guy sent on a wild goose chase to find a cable that will fix a problem that can't be fixed.
