How do i find out the sound quality of a CD?

A lot of steps are required to deliver music to a CD and many of them aren't 100% reversible, but we don't typically call CDs lossy.

Anyhow, I think people are specifically talking about lossy compression.


Oh yes, I'm sorry mixing up lossy process and lossy compression.

I need to know the sample rate (in KHz) and bit depth of each and every track of an audio CD. Some (or ALL) of the tracks sound more like 22/8 than 16/44 to me. In fact, although the CD has 78 minutes of music, it seems like some of them were just upconverted to 16/44, which only increases the size, NOT the quality of the sound, right? How can i figure this out? Is there a program that will tell me?

Thanks in advance.


Yeah, like everyone is saying, sources can be whatever and just because they're on a CD doesn't tell you much about what they might have been at some stage prior to that. But it appears the rogersbasement.com guy is combining various sources together, and once he puts it all together it ends up 16/44 because that is what a CD needs. If he's upconverting from a lesser source, it's only because he has to if he wants to include that track on a CD. And no, that can't increase the sound quality.

Just because a CD is pressed does not mean it cannot be lossy!
Yep, and that's why I used the word "typically" in my previous response.

I hope this talk about rogersbasement isn't violating TOS #9.

Go to this link to see what the bottom of a pressed CD looks like. It is the CD at the very bottom and you can clearly see that it is silver. Here is an example of the bottom of a CD-R disc, it has a green tinge. Here is another example of the bottom of a CD-R disc, it has a gold tinge.


Those images really do help.

Now, here's a pic of the bottom of the disc, and see if you figure out if it's a pressed CD or not.


Judging by just the color of the bottom, i think it IS a pressed CD, since it looks fairly clear to me.



I'm NOT a user of Adobe Audition, but i might be able to zoom in on the spectral analysis and/or sonogram within  fraction of a second in SF 7. However, i need to know what is a "hard transition"?

What would cause the audio ripped from a Laserdisc, DVD, vinyl or casette to become lossy, besides saving in .mp3, .wma, etc. format?

I tried that ATIP program, but when it opens it seems to report NOTHING. The descriptions are all empty, does that mean this is NOT a CD-R disc, then?

Very true. So, let's say the original source was analog (e.g. vinyl or cassette) what sound quality do they support?
