So are you saying that those hearing aids that are better in sound location do so because they reproduce frequencies beyond 20khz? I'd like to see some evidence of these ultrasonic hearing aids.

Well that depends on the type of birds...

Oh come on, seriously? this is a sound science forum. RBCD is a higher fidelity format than vinyl, including all the measurements which leads to an accurate reproduction of the soundstage in the recording mix, you know like crosstalk and frequency response. If RBCD sounds like carboard images...

That's not necessarily true. Vinyl playback (especially on lower quality or poorly calibrated turntables) produce a fake sound stage effect. Many soundbars also produce an intentionally wide (again fake) sound stage sound. Granted that in either case it is not a sound stage in the recording or...

The Austrian school of economics and their ilk are right wing nonsense and very much on the fringe of society and economics. The same can be said about your verbose views on ethics.

Your definition of a free market is contestable. Discrimination, just to name one aspect, is not force yet hardly ethical. To further complicate things, force can be an attribute of a free market.

Brain burn in?

I know, I was rolling in laughter after reading that one!

Is this a different take on the audiophile's wife hearing the difference from another room?

No, that would have been before my time. What I meant though, our diet of top 40 radio music in the 70s mainly consisted of Australian, British and US hits.

What's knowing about 70s music got to do with being an American?

Well, magnetic tape can store digital signals as well, eg DAT.

If you mean Jabra, yes. I have a pair of their higher end IEMs and quite impressed with them, particularly the software which adjusts each side to your hearing profile.

Damn, I should have asked for one to be done at the same time and posted the results here.

I had an ultrasound test on my kidneys the other day. I couldn't hear it or feel it (apart from the cold gel). I suppose I don't have superman hearing.

In keeping with the original topic, saw this good video on You Tube which pretty much explains what Gregorio had done with the OP.

There is the wispering wall in South Australia where a soft wisper can be heard 140 metres away due to a parabolic effect of sound waves bouncing along the wall. https://barossawinetour.com.au/blog/what-makes-the-whispering-wall-in-the-barossa-valley-so-special/

It is quite useful for LP playback with some records that may be slightly warped, that is the main reason why most high end phono pre-amps (or amps) have a subsonic filter function. Subsonic sound can also create distortions in audible frequencies either directly or through feedback through the...

Many (most) of Steve Hoffman's masterings are done through tube gear, for example Paul McCartney CDs. However I agree there is no such thing as a tube sound, unless you mean the type of distorted sound through tubes. The reality is that a tube amp can be as transparent as a solid state amp but...

Well, make a new thread. Most people that come to this thread is because of the topic heading.

What ever happened to 24bit vs 16bit?

The other thing that many don't appreciate is that most of these older recordings (eg PF Animals) were recorded on analogue tape. It is not possible to magically make the recordiings hi res simply by releasing it in a hi res format. The sound quality benefits from the 'hi res' releases typically...

Why do you cherry pick studies that have largely been discredited while ignoring those that stand the test of time to support magical thinking claims? I'm not convinced that you are not trolling.

Yeah but he uses an inferior Apple mobile phone which even in 2023, doesn't allow SD cards to expand storage. It's another way that company sucks in consumers by forcing an expensive upsell to a mobile with more capacity, which still isn't enough.
