D'oh. I worked out mm and typed cm. Ok even more of the opinion you cannot keep that still unless you have falled into the clockwork orange.
JN,
And a happy new year to you. Hopefully in the coming year you will learn the basics of DSP! 😉 !!!
Also included J.C., R.N.M., Tourney et al.

I just came across some old Motorola 56009 assembly code I did 25 years ago.
Before tossing it out I have concluded my brain isn’t what it was. Comments are for wimps it was hard to write it should be hard to read.
A well learned lesson! I often have to refer to older... What were we talking about?
Do you mean those 32 bits float things that are supposed to offer 1528 dB of dynamic ?
Please, please, oh, please, don't tell this to nobody, here.
With all the noise generated by those little 16/24 poor bits, go figure.
It will no longer be a small fold in space / time, of which Bonsai has established irrefutably the existence, but direct, a return to the big Bang. We could then start an interesting debate on what was happening 1 yocto second before and after.
Some scientists have speculated that this is what generated the Cosmic Microwave Background.
None, unless you like the artifacts of a signal with no anti-imaging filters at all applied.
Sorry, my poor english, is it an English expression for anti-aliasing ?
If yes, the need of it is not the proof that sampling frequency is not high enough ?

I like that, gotta remember it.
Wait, what??
Wayne,
I look at code I wrote 25 years ago, commented and all. I shake my head, even with comments...sigh. Every two or three years I have to revisit it to mod some algorithms. I look at the code and wonder who wrote it..
However, that is not as bad as going through 13k lines of spaghetti code written in a coding language I've never learned, by a coder who has no understanding of the hardware or control algorithms, with old revisions commented out, and working comments written by a non English speaking person.
That was fun.

... Then you can feel that the guy who wrote this was a genius ;-)
It happened recently to me, trying to read some Perl script highly concatenated I wrote long time ago. Comparing, the Engima machine is as dull as dishwater.
CD rate was a compromise based on hardware at the time. As far as I can hear, it's perfectly good. Clean, clear, sounds great, no noise. I'm more than happy with the format.
Vinyl was good at the time when I played a nightclub in 78/79, but I really abused the discs. The few cd's I bought to replace vinyl sounded much better.
Now I just listen at leisure while doing something, or blast it on the mobile rigs.

No anti-aliasing applies to the A/D process. Clock CD data to your DAC at 44.1kHz and send the staircase signal right to your PA there are lots of images at all the odd harmonics of the sampling frequency.
It is amazing how many people in this thread seem to think digital audio reproduction should have the same requirements and limitations imposed on the designers of real-time digital oscilloscopes.
"my brain isn’t what it was" - programming one of those wretched things in assembler will do that to you.
Thanks. I was focused on ADC. Sampling frequency rejection filter/low pass/smoothing. Got-it.

I think we are confusing Scott’s initial reference to the NOS cult with Tournesol’s normal state of confusion.
NOS in this forum’s context refers to the group of people who use DACs without oversampling or reconstruction filters and prefer it this way for a variety of (misguided) reasons.
That's not the first thing that comes to mind. First is cursing, followed by consternation, the phrase "what was I thinking", then denial.

It is you who should be embarrassed (in French "confus") to behave so badly on a public forum.
Now that they have all come forward, the lurker has the list of my ignored. Note that they all use the same procedures. All of the exact same way that Jneutron has well described. (strawman)
