Point the fan at a barometer, then lower its speed to zero, and tell me what you see.

I think the way the fan works is that it modulates the blade angle, not the speed of the fan.

Hi, is it possible to change the blur strength of the background artist or cover pic?

That's ridiculous. To have DC response it would have to be able to raise or lower the pressure in the room.

It can do that.

Obviously, no change because you aren't bringing any new air into the room or even sequestering air in a reservoir , just stirring up the air that is there.
Vinyl / Re: >20kHz content found in vinyl?
Last post by Arnold B. Krueger -
According to Wikipedia “Vinyl microgroove phonograph records typically yield 55–65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB.”

Based on my experiences with trying to measure the performance of vinyl, the only way to get 70 dB SNR is to use some sort of a weighting scheme.  Broadband 70 dB seems impossible in the face of the inherent low frequency disturbances that are part and parcel of vinyl playback.

What was your procedure?

(1) Obtain a collection of both legacy and modern test records. In many cases obtain 2 copies, one for general use, one for very limited use for tests that were done for "The record".

(2) Obtain several turntables ranging from Ion to Dual to Rega to VPI

(3) Obtain a number of legacy and current cartridges

(4) Do needle drops of selected tracks and analyze them to ensure tone arms and cartridges  are optimized

(5) Take the most promising results and duplicate tests using test records from the reserved group.

(6) Typically unless it mattered, I did some pretty merciless weighting of the results to give vinyl the best chance of developing results that people would not dismiss out of hand because they were so horrible. I edited out tics and pops by hand.

Generally what I found was that once I got the Rega set up well, it was hard to improve on it.  Oh yes, and that compared to digital, vinyl sucks. It measures so bad that it even sounds bad.
I have a M40 and a M50 and IMO there is not a lot of comparison between the two. I prefer the M50.
But notice that this is the M40X vs the M50, as I have read that the M50X is not worth it compared to the M50 or the M40X. Do you have the Xs? And can you explain why do you prefer one over the other? I am tending to buy the M40X with an upgraded earpath MH5 or something like that.

What do you think of this review?


I think the review is abject placebophile blather. :-(

I have a pair of M40s (OK, my wife bought them for herself with her money) and a pair of M50s that I paid about $110 for back before they started trending.  I don't see any reason why I would replace either, especially given that I have Neutralizer for my Android devices and Peace/APO for my PC's. 
He does make the point that earpads are easy to upgrade/replace and that there are options. I have headphones that I still want to use that I had to replace the pads on because the vinyl started flaking off.  I guess that I might flog eBay and see if I can get some with better cushioning.

That means lowering the low pass filter cutoff too, because of a lower sample rate. Thus removing the HF content that only higher bitrates can have.
Wrong! Every frame has exactly the same frequency content that it originally had.

The only reason that there is a relationship between bitrate and low pass is that encoders are smart and only preserve high frequencies when there is enough bitrate to warrant it.
While smartphones can have pretty good RMAA measurements, they don't necessarily have powerful enough output to drive your favourite headphones, especially when compared with dedicated portable media players.

The counterpoint is that loudness really only an realistic measurement if measured in dB's,  for which I will give the following reference a gigantic "fail":

Once we get those measurements properly expressed in dB, we find that there a few show-stopping differences, especially if we realize that a subjective doubling of loudness requires a 10 dB change.

The big outlier is the HTC One (M8) with a whopping V(out) = 1.28 volts of 2.14 dBV
The iPhone is high =1.00 volts or 0.0 dBV
My eyeball average phones are like the Nokia and Samsungs around 0.5  volts or -6 dB
The low ball is the Sony Xperia Z1 at 0.29 volts or -10.8 dB

I would expect that it takes  an approximate 3 dB difference to make a difference that you would reliably notice in a casual evaluation.

I have a Samsung S5 and my old, chemotherapy-damaged  ears tell me to be sure to pick some of  my more efficient earphones if I want an enjoyable experience. I feel that I can do that without loosing sound quality, especially if I use a little software product called Neutralizer to set Android's built-in octave eq.

Going from the Sony to the HTC could be a bit mind-blowing.

Also, like many other "smart" devices, even if they don't fail, they will easily become outdated. If I were you, I'd consider buying 2 or 3 cheaper phones over 10 years instead of buying one damn expensive hi-end one and wishfully expect it can last for 10 years, in terms of hardware longevity, software and accessories (e.g. battery)  support.

If the phone is running Android 5.1 , it will probably be able to run the vast majority of current software. If older than that, you may find things that you want to run, but won't run on your phone. 

It seems like 2 years from date of introduction is about as much support for OS upgrades that you can expect. With really cheap stuff, what you got is what you get. Forever, unless you are a software guru who can roll their own hardware-customized software packages. Android ain't Windows in many ways, and software updates is just  one of them.

About reliability of Chinese products, even if the brand itself is not from China, many internal parts are still made in China. Just make sure what you buy are not counterfeit products and it should be safe. Of course there are always exceptions, like the Samsung ones.

I'd say that if you are worried about gear with Chinese content or assembly, move to a different planet if not solar system. IME it is that endemic.

Google Photos does not allow remote hosting on a permanent basis, the images you are posting stop working within a few hours of linking them.

I never knew. Aren't the pictures in this post still visible?
Try changing LargeFieldsConfig.txt and see if that helps.

Ah, that would be the one I'd say, given 1900 characters were displayed while idle but not more (in mine the max is set to '2000'). Had forgotten it was configured in a standalone file.
