That's correct. Slightly qualified.
As I said before, many would rightly argue, and with very convincing merit, that 16-bit 44.1khz PCM is audibly indistinguishable from higher sampling rates and bit depth.
But it is generally not the exact bit-for-bit equivalent of the files mastered at the studio. Most of the need for higher capabilities in the studio, just like with video, is the ability to manipulate the digital files very heavily and to have enormous overhead to do that without running into problems, which is why they're usually done at far greater bit-depths(often floating-point) and sampling frequencies.
But once the work is done, 44.1khz/16 is extremely capable of resolving that master in an audibly indistinguishable way.
Uh, right. I said that before. But as I also said, it depends on the authoring choices by the studios. The capability exists, but it is not always utilized, again to save space or for other reasons, because it is largely not necessary. It provides basically the same audio quality as CD. Both BD capabilities and CD are a very significant step up from legacy lossy DD/DTS codecs as deployed on DVD.
What does it say about you who keeps replying in this thread with nothing much to contribute except false info?
What false info?
I have repeatedly explained to you both what/how studios record, why, and how that relates to consumer-deliverable formats. You clearly understand none of these things, and appear to have an extremely novice and rudimentary understanding of BD as well.
You continue to assert, with absolutely no reason, understanding, or factual basis that "CDs suck" and that "CDs are crap" despite many explanations to the contrary by audio professionals such as myself and others. CD is an extremely high-quality audio format that delivers a convenient and affordable consumer listening experience of enormously high fidelity that is audibly indistinguishable to the studio master. It is every bit as comparable to the audio quality delivered on many BD discs, quite a few of which deliver 48khz 16-bit PCM which is practically identical
to CD. And a huge portion of the remaining audio is just lossly compressed versions of exactly the same thing(48/16), which again is *ENTIRELY* equivalent to the audio quality ALREADY delivered by CDs for decades.Some
of what you find on BD will use 24-bit sample depth, and a very very few will use sampling rates higher than 48khz (96, 192)
You can examine all the thousands of BD titles yourself here:http://www.avsforum.com/avs-vb/showthread.php?t=1155731
Do you get it? BD is for pretty much 95% of titles THE SAME THING as is on CDs. It's just losslessly compressed, unlike CDs which used uncompressed PCM.
And if you want higher resolution audio than is offered by CD, such formats already exist! TWO of them!
SACD and DVD-Audio have been available for more than a decade!
So what is your whole purpose here? If you wanted more than CD had to offer, why don't you go out and buy high-res audio formats? There are quite a few albums out there in these formats. What is it that you want people to tell you? What you are looking for already exists
and has for a decade
