I didn't know I'm arguing. Then again this place has become so crazy for all the pseudoscientists I don't know what to do anymore...

Yes, he accomplished that, but imagine what he would have accomplished today?

Near the eruption the sound pressure level was much higher than that. 194 dB is just the sound pressure level equal to atmospheric pressure. At these levels we are talking about non-linear acoustics: Positive and negative pressure deviations do not behave the same way. Positive pressure doesn't...

Einstein wasn't 100 % correct about everything and did make some mistakes, but of all people in history, Einstein has one of the best track records of being correct in revolutionary ways... ...Einstein simply lived too early for quantum physics.

As I mentioned, the whole acoustics lab I worked in laughed hysterically at the products of Machina Dynamica some 20 years ago. Maybe I should start selling my own pee with vanilla flavour as unicorn pee and make a website claiming one drop of it put on a CD transforms the atoms of the CD into...

Audicity allows fast and proper methods of generating square waves. Here is the difference (12 kHz square wave at 44.1 kHz): On top the proper way and on bottom the fast incorrect way. Ironically the proper way results in a worse looking wave, but the better looking wrong way generates worse...

geoffkait needs his own corner here: Sound witchcraft.

Copy-pasting and modifying stuff from a PM I just wrote: Illegal audio signals mean going from analog and digital isn't theoretically 100 % accurate anymore because we have violated the requirement of band-limited signals. As is well known, sampling an analog signal with frequencies above...

There's tons of legitimate businesses selling nonsensical products. Some people are very gullible.

Audacity generates sawtooth illegally so that the result is an illegal digital signal. It "looks" quite perfect, but in digital audio signals are not "allowed" to be like that (there is no analog signal that digitized generates this type of sawtooth). In practise this may not matter to the user...

I thought Machina Dynamica is well known in audio circles for being possibly the most out there unicorn farts audio company in the World. Their products make "audiophile" power cables look sane!

I edited my post to make it clear what I was doing. Well, I am glad if this thread you created to further your understanding has done so. I am willing to explain these things (to my own ability which of course has its own limits) on anyone with any background. This is the sound science forum...

Note: Wrote here, but refers to a deleted thread: Nice! Troll creates a thread. I waste my time addressing the trolling. The thread gets deleted. Discussion boards have become almost completely useless waste of time. Meanwhile my posts get copypasted to blog. Nice day...

I don't see any problems with those quotes. I don't know where you took these numbers, but context matters.

No, but there might have been a risk of bursting coffee (including milk and sugar) out of my mouth.

I have to admit the products of Machina Dynamica have helped me to laugh a lot over the years. They are easily among the most ridiculous/comical audio products I have ever seen. If you knew how much we laughed at Brilliant Pebbles in the acoustics lab I worked in! Thank you for that! In a way I...

You are simply on the completely wrong forum sir! I'm sure there are discussion boards out there where people are "flat earthers of audio" aka audiophools and actually might welcome your pseudoscience. Try those.

Who doesn't agree to that? Of course band-limited square waves are band-limited! All square waves are band-limited. An ideal square wave is just an abstract concept like the number infinity. Sine waves are used, because it is very easy to graphically see what is happening to the signal, but you...

Yes. Of course I do. This is very basic stuff for someone with my education. Yep. Now, do you have a point? Where is this going?

Unfortunately! That's why we have flat earthers and Moon landing deniers. I consider myself an educated individual with critical thinking skills. It means I am ready to change my beliefs if need be, but also that any nonsense won't do. What you are doing here isn't anywhere near anything that...

My point was we wouldn't "do that to ourselves" without marketing. If we did, companies wouldn't have to spend tons of money on it. There is nothing wrong with fact based marketing. High-Fidelity/High-End related marketing isn't known for being very fact based. It is known for being often snake...

We don't believe what he says either. :dt880smile:

Bingo! Well, "brainwashed" is perhaps a bit too dramatic term here, but the purpose of marketing is to use our mental weaknesses against us. Marketing tries to make us "wash our own brains" by planting thoughts and manufactured associations in our head.

How often do you encounter "square waves" in the music you listen to? Theoretical square waves are illegal in digital audio. Digital audio is band-limited. Only properly band-limited square waves are allowed. Those can ben handled with ease if needed. By the time the transducers and possibly...
