  • A practical guide for why spatial audio music is great

    "More than high-res audio, I think Dolby Atmos music adds a meaningful and noticeable improvement to music."

    Yes, but Dolby Atmos is much better in high-res. So is stereo.

    I'm really tired of the gaslighting downplaying the benefits of high-res audio. Just because some people can't hear it doesn't mean the rest of us can't. Why have monitors over 720p? Why have cameras with more than 2 megapixel resolution? It's "good enough" for "most people", right?

    If we have the technology, and we do, we shouldn't be arbitrarily chained to audio standards set in the late 70's.
    OK let's first distinguish between recording and playback. 
    What we're talking about here is playback. 

    Let's also agree that human hearing is limited between 16Hz  and 20000Hz (20kHz) even though the vast majority of humans over the age 30 will be hard pressed to hear any frequencies above 16kHz.

    CD quality music was set to 16bit/44.1kHz. This is far greater than any cassette or LP sold in the 60's/70's/80's etc could ever attain.
    For one thing 44.1 kHz means that your playback medium can reproduce sounds up to 22.05kHz frequency. Well above the human hearing range, say 20kHz for an absolute perfect human.  
    The 16 bit part of the above number translates into 96 db (decibels) of dynamic range, meaning the difference between the quietest part of a track and its loudest part.
    That is way more than enough for any modern rock/pop tunes (typical dynamic range is 10-15db, let's be generous and give it an even 20db).
    Well mastered and recorded classical pieces can offer a dynamic range of say 30-50db, again let's be generous and give them 60db. 
    This debate about how much better are sampling rates and even more dynamic range (24 bit = 144db) is ridiculous when it comes to music that is targeted for human consumption.

    Now if you're doing scientific research and want to reproduce mating calls of crickets, or want to see how bats react to frequencies only they can hear, then yes the 192kHz sampling rate makes sense.
    If you want to reproduce dynamic ranges well over the 96 db (we haven't included dithering which can increase the dynamic range to 122 db) and try them on political prisoners, violating every written code of the Geneva conventions, then yes you may also need to go beyond 96db undithered dynamic range.

    But let me add a caveat here. If seeing 24/192 on your playback system's screen gives you a warm fuzzy feeling that you're getting much better quality than everyone else, knock yourself out.  

  • 'Apple Glasses' reportedly launching in 2026 or 2027 at the earliest

    Wasn’t it as recently as a year ago that “Apple car” rumors were hitting these pages with headlines like “to be released in 2023 or 2024”?
    This rumor sounds a bit like this. Predict something far off into the future and if it doesn’t pan out, then hopefully everyone has forgotten about it by then.
  • Apple Music Classical's best feature is lost on Apple's headphones

    Most Audiophiles who care about these things will not be listening through your common run of the mill, Airpods or Sonys or Bose headphones.

    They’re more likely to go with
    Focal Bathys: $799
    B&W PX8: $699
    Mark Levinson 5909: $999

    And the above three are just the wireless “but can also do wired”, options.
    When you start getting into the wired options, then all of the above prices look like bargain basement.
  • SIM card trays may disappear from iPhone 15 in Europe

    what a stupid idea,  they obviously haven't done their research
    or they think that US, Europe and Australia are the entire world
    almost all of africa and asia don't suport esim, including china, russia, indonesia, phillipines ets
    neither do some european countres, like turkey etc

    so if you do any international travel, you are screwed
    unless you want to roam and pay a fortune
    guess they don't want to sell phones to about 2 billion people
    Don't worry.
    The EU will step in and then iPhone16 will be forced to include a regular SIM, a mini SIM and a micro SIM slot for all phones sold in its territory.
  • USB-C on iPhone 15 might still require MFi certified cables

    Just remove the port entirely i say. Wireless all the way.
    While that may suit you, it’s going to be a nuisance for millions of new portless iPhone customers.
    You open your new portless iPhone box you get a magsafe charging cable. So far so good.
    Well now you need an extra cable for the kitchen. Yep used to cost $19 now that price went up to $39.
    How about the car? There’s another $39.
    Oh one more thing. Let’s stop calling Qi chargers with magnets wireless. It’s “inductive charging”.
    WiFi is wireless. LTE is wireless. MagSafe/Qi chargers are not.
