No, this 7 kHz I cannot hear as alternating. Anyone tried?

No, you cannot hear above 18 kHz, I cannot hear above even less than that. But we can still hear the shape of the waves at 7 kHz or even higher. And in order to reproduce anything other than a sine waveform at 7 kHz, the audio equipment requires 21 kHz. So we can hear if the audio equipment is...

Nothing in any of my posts or the video I posted above ever claimed that the Nyquist theorem is incorrect. Which is completely unrelated to the topic. Nothing posted here requires the Nyquist theorem to be incorrect in order to be correct.

Yeah the dying CD industry overlords will summon all their marketing firetruck teams to defend their silly 16/44 myths carefully planted over decades :)

Nothing in my post or in the video I posted claims that square waves do not require an infinite band. You probably posted to the wrong thread.

Ok, I was curious if after several days of discussion anyone will post the correct explanation of why HiRes music sounds better than CD, but nobody did. Apparently the dying CD industry overlords did their marketing job very well. Ok, posted it here...

Download the sample file from here and listen. Unless your equipment is not capable of reproducing beyond 20 kHz or you are 99 years old you will easily hear alternative patterns of different tone. One is a 7 kHz sin wave and another is "artificially constructed" square wave composed of 7 kHz...

No, there is no such effect that every Hi-Res track is better than CD. About half of them the same quality or even not good at all (taking a sample of about 500+ Hi Res tracks I've listened). About quarter of them (100 or 200 tracks) are a bit better, and the last 100 or 200 tracks are absurdly...

Oh well, that's what I expected, so no science on it yet, or it's not known at this board. No problem, I'll wait until it's found.

I thought that if this is a science board than someone can explain me why Hi Res sounds better than CD instead of trying to convince me that the sky is yellow.

And that also should have an explanation, you can figure out.

I gave a possible explanation why Hi-Res sounds better than CD on Tidal here: https://audiosciencereview.com/forum/index.php?threads/question-tidal-mqa-quality-without-an-mqa-capable-dac.54510/post-2232199 Another explanation could be that mixing engineers doing the final downsampling from the...

I suspect that the presence of some MQA tracks at Tidal contributes to the perception that Hi-Res music is better than CD. I clearly hear this effect myself because statistically speaking, an average Hi-Res Tidal track does sound better to me than an average CD. However, assuming that just 20%...

No they are not. All streaming services out there except Spotify are lossless, they do it to compete with Spotify, which is a complete piece of garbage but is still popular because most people don't care. You get worst case CD quality but right now Tidal already has over 10% of tracks (over 10...

@AnalogSteph 1. So true. In fact a parallel notch filter is my main weapon to greatly improve the speaker clarity and reduce distortions. This is why audiophiles say that DSP and active crossover speakers are inferior to the passive crossovers - there is nothing that can kill cone breakup...

As I posted in this thread the Equalizer APO is only good if you need to gently fix some small problems like cutting 2-3 Db in a few spots or improve the baffle step again by 2-3 Db. Trying to do any major correction will produce bad results. Post in thread 'Ending the Windows Audio Quality...

After few weeks of playing with Equalizer APO my conclusion is that it's indeed great when fixing a sloppy crossover work, however fixing the passive crossover and removing the need of equalization in exclusive mode sounds far superior to EAPO. After my last passive crossover redesign it's...

At any rate, I no longer care about measurement microphones, I have nothing left to measure. As I said here: https://audiosciencereview.com/forum/index.php?threads/ending-the-windows-audio-quality-debate.19438/post-2221636 at this stage of the system fidelity (thanks to the last link of EAPO)...
