That's another myth, or an anthropomorphic projection if you will. Power doesn't increase automatically on the opposite way of frequency in the bass and subclass region. You have to know the resonant frequency of the driver to make such assumption. This is because a driver has two functioning...

That's why audiosciencereview, erin's audio corner and stereophile exist. Why posting what is apprently technical stuff (with calculations) if you don’t use measurements at your disposal ? Taking for granted what could be an carfully designed experiment with private parameters can be seen as...

A huge part of the peaking of 600w can be thermal and not acoustical watts if the speakers have a very high EPDR and the track used pushes a lot of energy precisely to the point of this EPDR. Hence the relatively low loudness and the high wattage. (Topping is not responsible for a high EPDR) By...

An analogy has the form : a is related to b as c is related to c. "as" represent an understanding model that can fill the hole if on of the a, b, c, d is missing. It works all the way around : if you have a and b and c and d, you may build the model of "as". If the analogy works like this, it is...

In fact maybe too short because you totally miss the point. "Brightness" or "luminance", whatever (although I never heard an audiophile saying "this speaker has too much luminance"). My point is that your analogy is not an analogy. And the reason for this is that "dark" and "bright" have a...

I'm sorry. I'm taking the risk of inducing lengthy post but it's to irresistible for me. Nope. Frequencies are related to colors, not brightness. So I don't really understand in what way your analogy is an analogy. Maybe you have an subjective conception of optics, and an subjective conception...

To me, a lot of audiophile think that their relation with their gear is the same kind of relation that the musicians have with their instruments. It's a kind of Munchhausen syndrom, the illness is thinking that the finger of god can touch a soul the same way It can touch some kind of hardware...

It's a very romantic point of view that, for instance, don't apply to classical violinists and classical music critics. Studies have shown that they do prefer modern instruments over ancient and expensive ones in blind tests. If they say that a stradivarius sound superb, it's obviously for...

Ok, thanks !

I think that that's already the case in the dashboard. As I have uderstood it, the APx555 present a synthetic view of two measurement : with and without a notch filter. This is why you can see at the same time the test signal and distortions as low as -140dB. Am I wrong ?

Yes and the article's rigor is unbelievable from the logical point of view. I quote : "A quantum particle can exist in two mutually exclusive conditions at once. For example, a photon can be polarized so that the electric field in it wriggles vertically, horizontally, or both ways at the same...

Yes, but the oversampling thing is totally BS if you just think of it just two seconds. Because a large part of the audio band is already oversampled, and not with "computed" or "reconstructed" but with real samples. For instance, the piano's A0 fundamental is already oversampled more or less...

Great post ! Thanks ! So ffmpeg sox dithers by default. The command line is must simpler indeed. But sox doesn't preserve album art.

It doesn't matter for a sub. That's probably the good way to do it. But you have to keep in mind that the higher the crossover will be, the higher the room modes will come into play (I suppose that you know the stuff about bass localisation and crossover frequency). If you always listen at the...

Assuming that all tracks are in a folder and you are in a console in that folder : for x in ./*.flac do ffmpeg -i ./"$x" -c:v copy -af aresample=resampler=soxr:precision=28:out_sample_fmt=s16:out_sample_rate=48000 ./convert/"$x" done Converts all tracks in 16bits / 48Khz. Covert arts are...

I agree. Einstein's theory of relativity is not a conceptual achievement, just an heuristic achievement. He collected data about the the deformation of space-time (he has in his hands a space-time deformation measurement tool), sum them up and voilà ! You (with @Vacceo) really don't know what...

My guess is that the point is not objectivist vs. subjectivist but editorial concurrence. Objectivist's forums steal readers. That's all.

I agree. I see Rob Watts new technical and perceptual achievement as the result of multiple panic attacks. PTSD can destroy a human being you know...

For what is worth : Aristotle as the first scientist. "Science" is the common translation, via the latin scientia, of the greek épistémè. The treaty of épistémè is the "Posteriors Analytics". Epistémè is for Aristotle the true knowledge. It's a deductive knowledge. It has characteristics that...
