Is this the same used in the 8088 mph demo productions end credits? https://youtube.com/watch?v=yHXx3orN35Y

Reminded me of Mean Streets, with it's RealSound[1] voices https://youtu.be/WJ4rYt8v--4?t=153 Was amazed when I heard it for the first time. [1]: https://en.wikipedia.org/wiki/RealSound

I agree, even as a young kid with no idea how make the speaker even go beep (I was young, ok?) hearing the music/speech coming from Mean Streets was amazing. Everything else up to that point was just beeping and blipping... IIRC the volume was very low though.

Makes you wonder what the difference is, genetically speaking. The one set of genes codes for a crystal oscillator and the other for resistors and capacitors or the biological equivalent.

This is a really interesting area of research. I've been following roughly since the time I wrote the code I described above (at UCSF, a medical research institution). At the time, my genetics professor (Nelson Friemer) theorized it was primarily genetic ( https://www.sciencedaily.com/releases/2009/07/090702170209.h... ) and even found some genetic associations. I don't think that's really super-important. For exampl…

The big question is: what is the reference?

"[...]a built in boot sound on your machine which felt so good on Macs[...]" Ever since I got my first iBook in college I've had mainly negative associations with that sound. Too frequently you'd open the thing in the middle of a lecture with 100+ people in the room and the sound starts blasting. The only solution I found was plugging in headphones so that the sound would go there instead.

As I recall, if you muted the sound before shutting down it would stay muted and not play the startup sound. My Mac experience starts at the white iBook G3 running OSX 10.2 though, so it could be that this behaviour is a new thing. I now have a 13" TouchBar MacBook Pro and it makes a sound when I plug the charger in no matter what I do to the volume settings. When I have it muted and open I can actually see it unmute…

Yep the muting already worked back then. So it always came down to crossing your fingers and hoping you muted before you left the house.

Just fyi: I believe (but haven't gotten to try it myself) that this command will turn off the power chime when you plug in a USB-C charger.

The big question is: what is the reference?

reference to what? There is a collect of hair cells that vibrate in response to various pitches. When presented with enough training examples, the brain makes the association between those vibrations, and labels provided by others (that's where the pitch/note mapping comes from). For individual frequencies, I think most people with perfect pitch spend some time with pianos and tuning fork and eventually get a "feel" for what delta 1hz around 440 sounds like.

Explain my four-year-old hearing chords played on a piano by the teacher, and able to tell the notes that made up the chord. First 3-notes, 4, 5, 6 and he was still able to do it.

Sure the labels are learned. But the ability to hear all that is spread out over a bell-curve. The whole class could tell 1 note, 1/3 could tell 2, then 2 kids could tell 3, then just 1.

yes, and? I don't have perfect pitch, but with extensive training I have limited relative pitch. It's an acquired skill like anything else, and young kids exposed to music pick it up faster- with a distribution, like everything else.

Oh, and he has perfect pitch. Can tune stringed instruments without a reference, was employed to do so for some summers.

It was something he could do, from a very young age. Not apparently learned. Not learned by most of his cohort at music school, so I'm guessing most likely something born with.

If there is a distribution, then we have to task to explain that. Reasonable to call it genetic? Why not?

I don't know what you mean by "not apparently learned". Even with genetically inherited perfect pitch, the skill has to be "learned" (IE, presented with note labels). Nobody has the ability- without training- to tell you the frequency of a note. Genetic (in this case) doesn't mean "born with the ability", it means "predisposed towards greater ability after training").

Personally, I'd start with the strong observations like "People whose first language is tonal are more likely to have perfect pitch", while people whose ancestors spoke tonal languages, but were raised with a first language that isn't tonal, are less likely (and vice versa). That says to me "environmental differences" are as strong as genetic.

All of this is covered in extensive (and relatively accurate) detail on the wikipedia page. if you want to argue with me further, I suggest getting a PhD in the field, or at least extensive experience with molecular biology, genetics, biophysics, experimental design, and scientific philosophy, as all those are necessary prerequisites for discussing complex traits that have both genetic and environmental components.

I guess I'm not making myself clear. The ability to learn this accurately is not the same for everyone. Those that can, are said to have 'perfect pitch'. What makes them different?

Not just the learning - as suggested, maybe that's teachable (but probably not, look at all the advanced music students that never learn). But the speed and facility are not teachable - that came with the person.

Which is about the same as said above I guess.

And Really? Appeal to authority?
