  • HomePod 15.1 update brings Apple Music Lossless & Dolby Atmos support

    hucom2000 said:
    It still boggles my mind that we can have lossless on a HomePod mini, but not AirPods Max…
    I remember a discussion on this several months ago. 

    From Apple website: https://support.apple.com/en-gb/HT212183
    Can I listen to lossless audio using Apple’s Lightning to 3.5 mm Headphone Jack Adapter?

    Yes. The Lightning to 3.5 mm Headphone Jack Adapter is designed to transmit audio from the iPhone’s Lightning connector. It contains a digital-to-analogue converter that supports up to 24-bit/48 kHz lossless audio.

    —> So, yes on headphones with analog 3.5 mm jack.


    Can I listen to lossless audio using the AirPods Max Lightning to 3.5 mm Audio Cable?

    The Lightning to 3.5 mm Audio Cable was designed to allow AirPods Max to connect to analogue sources for listening to films and music. AirPods Max can be connected to devices playing Lossless and Hi-Res Lossless recordings with exceptional audio quality. However, given the analogue-to-digital conversion in the cable, the playback will not be completely lossless.


    So the work-around I heard discussed is the digital to analog DAC in the Lightning to 3.5 mm Headphone Jack Adapter into the Lightning port, then the Lightning to 3.5mm Audio Cable (it should be called Audio to Lightning cable) to AirPods Max.

    It sounds like a double conversion could lose something in each step, but the discussion was that it sure beat the hell out of Bluetooth.  I’m wanting to find a Lightning to Lightning cable and try it. 

    What I remember in the discussion by some audiophiles is that you don’t get all the way to the “pure” lossless, but you get pretty darn close.  And since there are many who can’t discern the difference between a high quality lossy codec (AAC?) and lossless, I’d say I’d be pretty happy with “pretty darn close” to lossless.

    But my hope is based on one discussion.  I hope a high end sound engineer writes an article on this. Is anyone on Anandtech reading this? Or at Audiophile Magazine?

    Could AppleInsider interview a sound engineer and do some double blind testing?

  • Mini LED coming to 11-inch iPad Pro in 2022, Kuo says

    Simple:  OLED can experience burn-in of graphics that appear for long periods of time. Also, and related, the”O” stands for organic.  Organic compounds usually don’t have the lifespan of inorganic compounds. In OLED, blue has a much shorter lifespan than Red and Green. This could lead to color fading and inaccurate color over time—YMMV.  
    The biggest advantage of Mini and Micro LED can be in brightness. OLED can achieve up to 1,000 nits of brightness, while inorganic Mini and Micro LEDs can emit up to 5,000 nits of brightness Mini LEDs can approach the blacks of OLED depending on the resolution used for backlighting ( which is getting higher all the time). Micro LEDs match OLEDs in blackness values. So, contrast ratios can be much higher with Mini and Micro LEDs, compared to OLED due to the higher brightness. 

    They’re getting really good results with Mini-LED. Plus it’s a run-up to Micro-LED, in a not obvious way—more in manufacturing than in as a back light for a group of pixels vs. a light for each subpixel of R,B,G,G respectively.

  • Lunar details a 'very exciting time' for high end Mac Pro, Apple Silicon

    This is an uplifting article with insight into real life consequences of Apple’s intense focus and skills in integration of software and hardware. 
    I work in high level photography and design. My work is faster, higher quality, and a pleasure to produce with the tools I now can use. 
    Video and 3D artists have much more complex workloads than I do, so I greatly appreciate D.E.D.’s concise yet very deep look into how these complex and demanding workflows are are so vastly improved due to Apple’s integrated design culture. 
    I set aside my work in 3D fifteen years ago due to its time demands hurting my productivity in my specialty areas. I feel I can now revisit 3D and put it to good use in content I produce. 
    Nice one, D.E.D.!

  • Dutch antitrust regulators launch probe into Apple Pay

    Sarkany said:
    Secure? Funny. I guess you didn’t read the article with the WiFi exploit. Who knows what kind of security hole is being exploited this very moment by a bad actor on Apple itself or their devices. Get real.
    When you load your card onto Apple Pay, it is encrypted and sent to VISA, MasterCard, or whatever company manages the card. Then VISA eg. will issue a different set of 16 digits encrypted to send back and be stored in the Secure Enclave silicon on your iPhone. Only VISA knows the new 16 digits and only VISA has the encryption key. The Secure Enclave does not communicate without encryption, and only VISA can translate the encryption. New keys are used on every transaction. VISA et al only collect info that would be collected to make the payment, the same info collected with a card transaction.

    Read up on it at Anandtech.com or ArsTechnica.com via search on sites. AppleInsider may have an archive article on the subject as well.

    It’s so secure that credit card companies and banks offer a discounted usage fee to Apple. 
    As in the VISA example, not even your bank knows the key. VISA does the communication with your bank directly.

    If you don’t trust a company like VISA and their communicating with your bank, then you don’t have any cards at all. As far as the Secure Enclave, it is silicon that would be destructed if it is tampered with physically. Software-wise, the encryption is safer than using a card directly to pay for something.

    Be happy, not cynical. ߎ栦amp;nbsp;(emoji for musical notes).

  • OWC unveils Thunderbolt Hub with multiple Thunderbolt 3 ports

    Larry O’Connor, owner and founder of OWC (OtherWorld Computing aka MacSales.com) had an interview on MacObserver.com earlier this week. He’s a geek’s geek. He started OWC at age 15 and has grown the company and product line to be a significant and very reliable supplier of Mac peripherals and storage solutions. 

    He explained that PC suppliers have often offered TB3 that was only partially implemented. 
    He further explained that Thunderbolt3 (TB3) has always been fully implemented on Macs and that we’ve had it good on the Mac.

    TB4 is actually TB3 as we’ve had on the Mac all along (40 Gb/s). The difference is that it will be certified on PCs only if it’s the full implementation under the new USB4 spec. 
     
    Meanwhile, USB4 is now 40Gb/s. The new standard for USB4 includes TB3 and power requirements of at least one port supplying 100 watts of power  it also enforces capability of 4 port hubs or docks plus  capability for both USB4  & TB4 (te TB3 we’ve already enjoyed on Macs).   
    The 4 port dock should work under Big Sur on all TB3 Macs. The cables have to be certfied as USB 4 as well and they have to be able to carry 100 watts of power. 

    I’m not sure why OWC is only varying 60 watts of power.
