Let say a driver's frequency range is 800 Hz to 20k Hz. (From the manufacturer) Is it safe to crossover at 800hz or should it be crossover at 850 or 900hz? Is it possible to damage the driver if crossover at 800 Hz without a steep slope? (Let say below 48db/oct)

The link I provided talk about barometric pressure : there's no impact on sound.

There's no link with speed of sound ans equipment. But there more chances to have an effect on our ears. But if humidity has an effect on what we hear we should have the effect on everything we were : cars, people talking, etc. Maybe there's more impact on our moods.

Maybe there's a link, sound travels faster with high humidity http://www.sengpielaudio.com/calculator-airpressure.htm But I doubt it's audible

At 24 bit I wouldn't be concerned at loosing resolution.

It seems that the group no longer exists.

This is impressive!

Wondering which manufacturer gives the most detailed specs. I'll start the list with : Emotiva and Neurochrome

If you managed to install it with Ubuntu, there's no reason to install wine. If your microphone is recognized by Ubuntu you're ready to measure your room.

Do you still have the service manual? I found it on hifi engine etc. but it's only the schematics. I'm also having the 0 MHz isdue. It worked for a day. When I powered it this morning stuck at 0, an seems to work.

The latest REW file is 5.19

That's the same thing they recommend at audio nirvana https://www.avnirvana.com/resources/rew-linux-installer-requires-java-7-or-8.18/

Have you tried to run the sh file? https://askubuntu.com/questions/38661/how-do-i-run-sh-files

I managed to installed it last year on my ubuntu laptop. Can't remember what I did, I'll check to see if I can find.

Do you still have your meadumeasure files? It would ne interesting to see the bass respons without smoothing. I think it's a 1/3 smoothing?

Yep, search for comb filtering for high frequencies.

From Neumann web site Above 14,000 Hz: Air band. This area is important for recordings that want to sound “expensive” and “super-hi-fi.” It gives voices and stringed instruments an airy feel, hence the name. It does not contain much musical information, though...

It depends which microphone they used un studio. Chances that they used microphones that record well above 20khz for all instruments is weak. Real quick search brings me this https://www.google.ca/amp/s/blog.audio-technica.com/microphones-frequency-response-important-know/amp/ Gearzluts...

Not a magazine, but a good blog for equipment review and testing https://archimago.blogspot.com/?m=1

REW is just another analyser, more sophisticated ans free. A lot of people use it. REW can create EQ filters, but you have to know what you want. You then need an equalizer or a DSP. Note that a digital eq, on a computer can also be used.
