Does anyone know how this is being done on device?
This is content analysis, just like Photos has been doing for years now. When it's analysing your photos for content, so that you can search for "cat", it's also analysing for nudity.

Now where this does relate to human hearing's maximum frequency, is the fact that humans can't generally hear more than 20kHz. Sampling at double that rate means there will be no aliasing errors in the audio - where parts of the audio could be "missed" essentially, as the samples might fall on two sides of a frequency peak. This is known as the Nyquist rate. The sound between the samples is effectively interpolated (averaged), and of course the higher sample rates mean there's less averaging going on. Audiophiles claim they can hear this, but double blind tests have shown that almost no one can actually tell the difference. And the Nyquist rate says 44kHz is plenty high enough to accurately reconstruct a 20kHz signal, proving that high sample rates are pointless.
The bit rate is inversely related to how much of the original audio is thrown away, and how much the MP3/AAC/whatever decoder has to "guess" to reconstruct the audio.
Regarding audio quality and this 192 kHz sample rate: earlier this year, announced immediate availability of ’s music catalog in 192 kHz/24 bit Hi-Res Lossless format (although limited to a subset of the catalog at first)—at no extra cost!!
What is mind-boggling is that ’s hardware is limited to 96 kHz—why?
—my antique +20 year old Denon AV-receiver happily supports uncompressed multi-channel audio in 192 kHz, but neither my TV 4K 2nd gen., nor my Mac mini M1 is able to take advantage of Music’s reference-class format! AFAIK, there is no technical reason for this HDMI-output buzz kill 🤒
There is no practical benefit whatsoever from going above 96kHz. That sampling rate can accurately reproduce any signal up to 48 kHz.Only some percussion produces audio up to that range, and virtually no microphones go beyond about 20 kHz.Our hearing tops out at around 16 kHz at birth, dropping dramatically from there over time.
In fact, unless you are talking about super high-end converters, going to extremely high sample rates is likely to introduce ADDITIONAL intermodulation distortion that can affect the high frequencies. All double-blind tests where people have been able to distinguish super-high sample rates were cases where people were actually hearing distortion.In the case of a built-in off-the-shelf $1.50 (if that) logic board D/A converter, going to 192kHz is almost *certainly* going to sound worse than staying with the already-overkill 96 kHz.Even ignoring the fact that absolutely NOBODY with playback equipment capable of reproducing that resolution is going to be playing it from a 3.5mm minijack output on his laptop.That’s just ridiculous.
approx said:Yes that’s great. But it is still not possible to import Video from Sony SXS Cards. SXS Cards are used in Sony and Arri Broadcast and Cinema camerasWe are waiting since one year to get a updated device driver for SXS Cards.Without this updated driver, the super fast M1 MacBook Pro is useless for our job. Ingesting Footage is impossible.So sad!However, in general, I’ve found that professionally used systems are ideally kept about one year behind, to let the software work out its kinks.So, we’re still within limits, I suppose.I’ve some plugins that didn’t see Upgrades for three years, before finally adding support for the very latest systems… I guess the team rotates between projects and only gets around to updating when it’s that plug-in‘s maintenance turn.

At least we can (usually) tell if it supports Thunderbolt from the TB logo on the connector, but beyond that…
