One, most computers do not have 48kHz audio as native on their audio cards. 48kHz is standard for video recording and video editing. 16/44.1 was also a video standard and is why Red Book CDs are 16/44.1.

You would need to convert your 24/192 file to 24/48 or 16/48 to play the file back. Proper down-sampling and conversion from 24 to 16-bit does not just throw out samples per se. Missing samples would yield clicks, pops, a change in time and sync issues, not to mention aliasing. This is not what conversion does. There are all kinds of applications to convert files. There is no reason to do it the wrong way.








My edit was making some pre-existing key words bold for emphasis.

Brent, yeah, the way you said it the first time made it sound like you believed in soul sleep, which as I said is the belief held by SDA, that you sleep in a unconscious state until the resurrection. Your second explanation made more sense. You are right to say we are not in Heaven or Hell as in our final judgement or reward, however, Jesus story about the rich man and Lazarus seems to confirm the ancient belief that souls await resurrection and judgement in the place of the dead, which in Hebrew was known as Sheol and in Greek was known as Hades. This two compartment place described in that story held peace for the righteous and torment for the unrighteous.

I'm sorry, but you don't seem to know what you are talking about. Converting from 24 to 16 bit simply involves cutting away 8 bits. You can add dither noise before that if you like to carry over some info from the lost bits... But that hasn't anything to do with sample rate conversion anyway... But I won't spend time trying to convince you because I know there is no point in that.

I brought up conversion because some people with old computers are not going to play and store 24-bit files. Most modern OS's and cards allow for 24 bit, and many up to 192kHz. So throwing samples away is moot to me. If you throw away samples, you get aliasing and other artifacts plain and simple. Case closed. This is not how anyone does it. Prove me wrong and I will be surprised. Well, prove me wrong with a pro application/device.

Re: changing bit depth, converting a 16-bit file to a 24-bit file requires zeros to be added. You know that going the other way is different and sounds differently. As for even math, I let the mastering house convert from 24 to 16 bit, but I do sample 88.2kHz, so the math is even and there is no decimation.

Sure you can truncate samples if you want to, but that is not a proper dither from 24 to 16 bit. In fact, in some instances, it is better to resample. There are many forms of dither + noise shaping, some better than others. But in audio, truncation is just not a viable option in my opinion. It is not an acceptable practice to most engineers, mastering engineers, etc. I vote for a random averaging up or down.

I have pondered this, but Jesus went to Abraham's Bosom and led the saints out, so, would this be the case today? Paul said to be absent from the body is to be present with the Lord. I think the error is when people bind the soul to the body. I have wondered if Paul isn't using some figurative poetry, referring to the bodies "sleeping".

Why would there be aliasing if the 192 kHz sound (as you claimed yourself) doesn't contain any frequencies above ~24kHz?

I know that some believe that because of Matt. 27:51-54, but it really just says that the tombs broke open and many holy people were raised to life. Not ALL the holy people and nothing about Jesus leading them to Heaven. If you are getting that idea from another reference, let me know. It is certainly conceivable that the spirits of the righteous dead go to be with the Lord in Heaven, since ascension, and that they are reunited with their bodies at the resurrection or it could just be that things are as they were and that everyone still hangs out in Sheol awaiting that day. Some of the things Paul says do seem to lend to the idea that death means presence with the Lord. However, Jesus also told the thief on the cross that he would see him in Paradise, which was probably the same thing as Abraham's bosom, so if that's the case, then the Lord's presence would be there or at least could be there. Either way, I think it's reasonable to assume that the wicked still go to the torment side of Sheol to await the final judgment.
