You act like this is new. How else did so many at the upper levels of Government become fabulously wealthy, on Government paychecks, if not for internal payoffs? Bill Clinton went from ~$700,000 to $100,000,000+ in 10 short years. Chellie Pingree went from $12,000 to $40,000,000 in just 5 years, and Nancy Pelosi went from under $1,000,000 to $200,000,000+ in 30 years. It seems that the normal modus operandi to this point has been to privatize the profits for those in "social service" roles, and privatize the losses - as the average private citizen has to pick up the losses via higher taxation.
I'll just say that, if you review AES and ASA papers, you'll find that frequency response is about equal with CSD and IMD/THD levels in terms of preference. EQ can fix just one of those, but leave the others undone and you're screwed - no matter what you want to do to the EQ. Have a poor CSD or high THD/IMD and no matter how flat you make the frequency response, it will still sound poor.
If you knew anything about filter theory, you would understand that adding a minimum phase filter to a non-minimum phase filter will result in a non-minimum phase system. You cannot correct for nonlinear effects with linear filters.
1. THD is VERY hard to hear. IM distortion is what is annoying.
False. Go and check any of the AES papers by gentlemen like Louis Fielder, Grant Davidson, or Dane Grant (all gentlemen I work with weekly). THD audibility is dependent upon SPL and frequency, and levels as low as 0.5% are not only audible, but objectionable based upon the spectrum of the THD.
Don't believe that? Perhaps Dr. Earl Geddes' presentation on the audibility of distortion will help. Of course, when you live in a reality distortion field, I guess THD might be a good thing!
2. Even Audiophile-quality (whatever THAT means!) Subwoofers generate around 25-30% THD when they are crankin'.
Really? In 2004 I was well below that level, and later I took it to >100 dB SPL with single digit THD. You're flailing here. Oh - and these SPL levels are a solid 20+ dB beyond the HomePod, meaning literally 100 times the sonic power, with one quarter - or less - the THD.
3. To get that 56%, he was driving the woofer to within an inch of its life.
Funny, because it can't move even close to an inch, or even half an inch.
And here are his comments in the "Distortion" Section:
"If we look at the Total Harmonic Distortion (THD) at various sound pressure levels (SPLs) we see that Apple begins to “reign in” the woofer when THD approaches 10db below the woofer output. Since decibels are on a log scale, Apple’s limit on the woofer is to restrict excursion when the harmonic distortion approaches HALF the intensity of the primary sound, effectively meaning you will not hear it. What apple has achieved here is incredibly impressive — such tight control on bass from within a speaker is unheard of in the audio industry. [...] Even though Distortion rises for the woofer, it's imperceptible. The (lack of) bass distortion is beyond spectacular, and I honestly don't think there is any bookshelf-sized speaker that doesn't employ computational audio that will beat it right now."
So he likes the sounds of the compressor kicking in, and he believes that you cannot hear which, provably, you can. And he's - like you - a self-admitted Apple fan. The bottom line is his measurements are middling performance at best. And yes, I work in this industry, I design speakers, and you HAVE heard my work - guaranteed. Probably directly (SONOS, Polk, Genesis, Infinity, Beats, Blue, Audioquest, Mackie, EAW, KRK, Polycom, Microsoft, etc.) or indirectly (monitors for Mackie, Event, KRK, microphones for a dozen brands, etc).
The HomePod is an interesting idea - but it's got, at best, middling performance. These measurements confirm as much.
Airplay can do Redbook audio if your SOURCE material is that bit rate (good luck getting that on to your phone, though). Apple Music is 256 kbps; you'd have to do your own rips to get to redbook (16/44.1), but you cannot do high resolution audio at all. Period. Nada. Apple doesn't care about high quality audio - just Beats and earpods and a mono speaker it claims can be full stereo (but which, in reality, it is not per lots of reviews, not to mention the laws of physics).
Just the comb filtering one would expect from a radial array of broadband transducers! And it cannot be solved with any amount of DSP save for a singular 3 dimensional place in space (which is where the listener would be, not the speaker).
There is actually nearly 100 years of data showing that the dynamic range of the auditory system is around 140 dB SPL. So that would imply 24 bits needed to capture that range.
I was a sound tech, way back when, but for the last 20 years I've spent 99% of my time designing speakers and headphones for everyone. And if you think and EQ is all you need to fix problems with speakers, well - best go back to just running snakes and taping them down, you have a LOT to learn. EQ will not fix IMD, THD, dispersion, comb filtering, dynamic compression (thermal and positional/BL), CSD issues, and many, many more.
They have it! In fact, they have nearly eleven times that type of audio, since it streams a solid 256 kbps! Oh wait, you mean 24 bits per PCM sample? Sorry - you have to go elsewhere for high quality music...
Apple Music is your only streaming source. You can use Airplay (Apple-specific) to stream from your phone to the speaker, but every time it starts or stops you have to reconnect your Airplay stream and start again. So if it's not Apple Music or an iPhone - you're SOL.
Nope. It's Apple Music, or Bluetooth/Airplay. You're limited - by the Apple ecosystem - to AAC, or MAYBE 24 bit/48 kHz if you have a Lightning output device. High res audio? 24/192 or 32/384? DSD? Sorry - no love for you in the Apple world. Even decent Bluetooth codecs like AptX HD and Sony's LDAC are barred from iOS (due to it not using/supporting CSR chips). Audiophile and Apple stop at source - and apparently that stoppage is now reinforced with a speaker that has 50%+ THD at average SPL levels.
I have an idea! What if everyone had a unique number, and they kept it secret, in something we can call a wallet. Then when they want to go to a class, they can add their number to a list of other numbers signing up for that class, and it will be hashed so that everyone can verify that they were added, but because it's done with secret unique identifiers it won't really be public, but kind of anonymous! Then groups of classes - we'd call them "blocks" - could be strung together for your entire scholastic career, like a "chain". I call it "BlockClassChain". And we can fund your education with special money that is pegged to this BlockClassChain, so it would be BlockClassChainCoin!
So the area that is 5 meters above sea level will still be at the same height, correct? We've just added more, lower altitude land around that area. How does that increase the susceptibility of flooding of that 5 meter section?
So what you're suggesting is that the outside boundaries increased, but the area inside - never below sea level, and now further from the seashore - has sunk?
Additionally, does the control system for the rocket respond fast enough if an random engine fails. Now what about 2? Or 3? Or 4, grouped together? A sudden change in thrust vector will arise if an engine fails, and the overall control system has to be able to account for that kind of failure throughout the entire flight - or the flight is a failure.
Often, adding parallel stages will result in lower overall system stability. Yes, you have redundant parts, but if it throws your system for a loop for long enough - you fail.
No, the average margin on their automotive products is negative; the GROSS margin is positive, but that does not include the cost of operations associated with those sales. Musk loves to trumpet gross margin - but that doesn't help you in terms of cash flow or profitability.
Kansas spends about $10K per student which is above average for the OECD (which is around $9300 per student, per my link from CBS News). So Kansas is low for the US, but above average for the OECD. And Kansas ranks 14th overall, even though it's spending is near the bottom.
Using the sources I've provided, Utah is at the absolute bottom in spending per student (over $3000 less per student than Kansas), but ranks 9th nationally. Perhaps it's not how much is spent - but HOW it is spent, and what the State and school districts see as the the goal of the educational system.
So far the only chipset that I've found that supports LDAC is the 867X series from CSR. If there's another one, I'd be interested to know it!

Quit with the crap!
Yes, you should!

The butt hurt is strong with you!
Apple Music is at 256 kbps. Airplay can do 16/44.1, basically redbook audio. No high res, though...
Problem is, right now, no matter HOW much money you give them you cannot get stereo HomePods. That's sometime "in the future".
Prove that Google and Amazon send constant update to their own servers, or STFU. That's the point - we have their "word" - and that's it.

That's the same thing that Amazon and Google say, and they're hated around here because of it. But I guess it's because this is Apple, we're all good?

Audiophile and Apple stop at source - and apparently that stoppage is now reinforced with a speaker that has 50%+ THD at average SPL levels.
THD in the lower frequencies (below ~75 Hz) is between 18% and 56%, per his own graphs. I guess that is audiophile?

China, India, and SE Asia contain 50% of the world's population. Europe, Australia and North America are about half that...
Amazon turned it around and became profitable before they ran out of cash. Tesla has about 2 quarters left to do the same thing...
