## Do CD's reproduce lower frequencies much better than higher freque

No hlloyge, you're not missing anything.

But is the sample rate for CD's the same for all frequencies

The sample rate is fixed. Now you might want to re-think what you said about each sample defining a wave twice per period since it is only true for one frequency: half the sample rate (AKA the Nyquist frequency). Well, at least I think you mean to say twice per period (twice per Hertz makes no sense).

I ask this because if it is constant regardless of the frequency being sampled, than CD's would be able to reproduce lower frequencies much better than higher frequencies.

No, this conclusion isn't correct, at least not from a mathematical standpoint. Thanks to oversampling, it's really not correct from a practical standpoint either.

surfasap, do you know what a sinc pulse is?

PS: Sorry about my edits. I have a feeling someone more intimate with the subject will be writing something much more useful, so I'm doing my best to not look like an idiot. Hopefully my premature response will not be quoted. This one's bad enough.
