Directly from the German horse's mouth:

Here's the video I mentioned before. It's much better explained than my word salad.

Argghhhh. You're adding even more complexity with a somewhat different situation. If 2 people are talking at fairly similar frequencies we'll have, let's say 70dB each, so 73dB total. But if one speaks at 80dB and the other speaks at 60dB, then we get 10log(10^8+10^6)=80.04dB. The added energy...

If it’s fully masked, then no. One way this happens, and even that I’m oversimplifying to a fault, is that when you hear a pure tone, there is more than just the resonating area that’s shaking in your cochlea. The area resonating just turns out to be where it’s shaking the most. So if you add...

How can you say that after watching the instant cult AI beer commercial. That thing was the biggest win in the history of winning!

And again, what does it have to do with psychoacoustic encoding? Of course the magnitude of change is important because at some point it will be perceived by a human if it passes some thresold, but in this case we need to know how loud it is relatively to what was estimated to be its masker...

My educated guess is yes. But if we're being science serious, I just don't have the data to know when something or a sum of things becomes audible. How often have you seen a conclusive listening test done for that? It's a problem when trying to draw a conclusion about hearing impact to not have...

If changing the FR is the objective of a consumer, then an EQ probably is a better choice than a different cable.

...transducer for both cables at various frequencies(the easiest estimation would be to use the formulas for voltage divider stuff, Vout= R2/(R1+R2)*Vin where the cable's resistance at a given frequency would be added to that of the amp) and then calculate the actual FR change between the 2...

OP’s headphone seems to have an impedance bump centered at 70Hz so the higher impedance cable will ”increase” that area(lower everything else more). But yes, silver sounding clearer was never a rule.

@Vamp898 Showing that there is a difference in data in a format that exists specifically to remove data and is called lossy, is one of those ”thank you captain obvious” moments. The entire thing is based on our ability to not notice certain sounds in a certain context. I’m not saying nobody...

The super generic answer with tunnel vision: A DAC will increase the sampling by filling in samples of the last value, or more likely with zeroes, and count on a filter to remove the extra frequencies born out of that. A computer allows you to calculate a specific value for each new sample. It...

It's been years since I really looked into the basic settings of REW(if it works, don't touch it), but I do remember something about a default -3dB somewhere(that could be removed). I'm not sure if it was just a visual thing(shown value) or if it was real to limit the risk of clipping, but maybe...

Come on now. @Brahmsian clearly said he cared about objective fidelity regardless of audible improvement. There is nothing wrong with that. Discuss what you want, and let him do the same. He's not trying to sell DSD, not telling us that we need to do the same, not inventing dubious reasons why...

You start with DSD VS PCM but end with 256 DSD VS 16/44. :wink: You can find some tentative estimate for PCM equivalence in DSD, but that's all it is and even then, it's only about the resolution output for what's on the file and there is the question of the usually remaining important noise in...

The answer will surprise you! :wink: How would you synchronize the content on various sources? It’s already rapidly challenging to do that with 2. There’s a master/slave problem too. And all that trouble for what should, by far, be the least significant area of the chain(with the possible...

A study that gives me pause. First because it's the first time I hear about relevant ultrasonic content in baby vocalizations, and a quick google search only seems to lead me to that one article. That could possibly be explained by how I suck at seeking info on the web. Second, it's a paper...

And we're back to the epoxy pyramid scam. I can't do this.

How many is a crowd in 2024?

From small crystals lying around in a weak electric field near some audio cables? You're actually serious about this.

If you don’t have enough personal experience to guess that in general, nice closed back headphones don’t have the best isolation, you can try to find information online. Rtings.com has an isolation test for example. Headphonetestlab also has some, and for old stuff, the innerfidelity pdfs show a...

Between pretending that the burden of proof is on us when claiming control over quantum entanglement and teleportation:rabbit2: , the always vague nonsense where sound isn't sound but is sound, and the witty but meaningless one liners, Geoff’s BS reached critical mass and a black hole is forming...

With the information I can find(almost nothing I looked for), I'll give my very best answer, IDK. From the few measurements I could see, those DAPs seems to do pretty great, but of course that doesn't mean they also do with a problematic impedance(that this IEM may or may not have...). So I...

You don't give us enough information. The impedance curve of the IEM would probably be a good start, and telling us what devices are used doesn't cost you anything and might let us know more(or not). How is the inadvertently high gain related to the rest?
