YouTube creators may be able to upload music that sounds like it was actually sang by famous musicians one day. According to Billboard and Bloomberg, the video hosting platform is developing an artificial intelligence tool that can mimic the voice of recording artists. It was also hoping to introduce the feature during its Made On YouTube event in September, where it debuted other AI-powered creator tools including a generative green screen. Obviously, its plan didn't push through, and it was apparently because negotiating with recording companies is taking time. The technology is new, after all, and there are a lot of questions that need to be answered first. 

Billboard says one of the key issues they're still hashing out is how monetization would work. Will artists be paid for the music YouTube feeds its AI model, or for the output made using the AI tool? Further, how would songwriters be compensated for any of their music used to train YouTube's AI? Recording companies still reportedly have questions about how the AI model is trained, as well, and about how artists will have the power to opt in or out. If and when the tool does come out, YouTube intends to beta test it first by giving a select group of creators access to the voices of artists who opt in. 

While negotiations are taking time, recording companies are receptive to YouTube's idea, according to the sources. That's because they're looking at the use of AI in music as an inevitability, and they're concerned about getting left behind if they resist licensing deals like what YouTube is offering. As Bloomberg notes, though, YouTube is walking a tricky path and may have to brace itself for legal issues in its quest to explore the use of generative AI in music. OpenAI, for instance, had been sued by a group of authors, including John Grisham and George R.R. Martin, for the alleged use of their novels to train its large language model.

Oppo's first two horizontally folding phones caught our attention with their shorter 9:8.4 "golden" aspect ratio, but with the brand new Find N3, the company sided with a more conventional design, which is backed by some new software tricks to boost the multitasking experience. Not to mention an upgraded set of Hasselblad-branded rear cameras, a vastly improved folding durability, and the alert slider inherited from OnePlus — as we've already seen on the recent Find N3 Flip.

The new foldable AMOLED display on the Oppo Find N3 comes in at 7.8 inches wide, with a resolution set at 2,240 x 2,268, which ends up being a pixel density of 426 ppi. As far as crease goes, it's even less visible than before, so it's definitely fair to call it "virtually crease-free" this time round. The more interesting feature here is the new self-healing coating, which can apparently smooth out scuffs to keep the panel in pristine condition for a little longer.

With the increased body height, the Find N3's cover display features a more familiar — and arguably more practical — 20:9 aspect ratio (though it's still shorter than, say, the Xiaomi Mix Fold 3). Here we have a flat 6.3-inch, 2,484 x 1,116 AMOLED panel (431 ppi), and much like the flexible screen, it supports 1,440Hz PWM dimming for less eye fatigue, 1-120Hz refresh rate, Dolby Vision, HDR10+, up to 1,400 nits in High Brightness Mode and up to 2,800 nits peak. This is noteworthy, considering that many earlier foldable phones have weaker display properties on the inner screen.

Oppo

The Find N3 is built with Oppo's third-generation Flexion hinge, which consists of zirconium-based liquid metal for compactness, as well as the company's self-developed aircraft-grade steel for strength. The flexible screen is also backed by carbon fiber support plates for structural strength, making the device "36-percent more resistant to warping than past-generation foldables." Better yet, Oppo got TÜV Rheinland to certify the Find N3's 1,000,000-fold durability, which is more than double that of the Find N2's "mere" 400,000 folds, let alone the Samsung Galaxy Z Fold 5's 200,000 folds. The fold counts remain at 100,000 for both the 50ºC (122°F ) and -20ºC (-4°F) tests. While there's no Ingress Protection Rating here, Oppo has applied a weather-sealing process to make the Find N3 splash-proof.

Photography is also a significant upgrade here. Find N3 is the first smartphone to pack Sony's 48-megapixel (4:3), 1/1.43-inch LYTIA-T808 sensor (it's actually 52 megapixels, 1/1.35 inches in full — 20-percent larger than the main rival's). This is apparently the first sensor to feature a two-layer transistor pixel structure, which is a cunning trick to let each pixel receive more light, thus more image detail. Sony goes as far as claiming that this chip "rivals the high-quality 1-inch type sensor." Additionally, this f/1.7, 24mm-equivalent main camera comes with optical image stabilization.

There's also a 64-megapixel, f/2.6 periscope telephoto camera with an unnamed 1/2-inch sensor — one that's apparently three times larger than what you'd get on a main competitor's foldable. With this 70mm-equivalent lens, you get 3x optical zoom and 6x "lossless" zoom (by cropping), both of which are assisted by optical stabilization via a floating prism structure. You can use the same camera in Hasselblad Portrait mode.

Last but not least, the 48-megapixel, 14mm equivalent ultra-wide camera packs a Sony IMX5811/2-inch sensor, which Oppo claims to be 130-percent larger than key rival’s. It comes with an f/2.2 lens, a 114-degree field of view and macro shot support down to 4cm.

Oppo

To complement the photography hardware upgrade, the Find N3 packs a new Oppo Computational Photography (OCP) feature, which captures the original brightness information for fine-tuning each HDR shot "pixel by pixel." The result is supposedly "a more natural image with rich highlights and shadows." This sounds somewhat like what the now-retired MariSilicon X imaging neural processor would have handled in the past, but Oppo has yet to dive into the technical details on OCP. On a related note, the ProXDR display mode in the gallery app leverages OCP details to optimize the screen’s peak brightness, in order to make the photos pop; but you can also long-press the ProXDR button to see the photos as-is.

For video calls, you also have the option to use either the external 32-megapixel f/2.4 selfie camera (1/3.14-inch, 22mm equivalent), or the internal 20-megapixel f/2.2 counterpart (1/4-inch, 20mm equivalent).

As for the remaining core phone specs, the Find N3 is unsurprisingly packing Qualcomm's flagship Snapdragon 8 Gen 2 processor, along with 16GB of LPDDR5X RAM, 512GB of UFS 4.0 storage, a dual SIM tray, NFC, a triple-speaker system (with spatial audio support) and a larger 4,800mAh battery. With 67W SuperVOOC charging support, the device reaches over 80-percent charge in 30 minutes, or a full charge in 42 minutes. You'll find the new alert slider (silent, vibrate and ring) located right next to the volume rocker, which is above the side-mounted fingerprint reader. The whole package comes in at 239 grams heavy and 5.8mm thick when opened — not record-breaking numbers but still impressive in this category.

On the software side, Oppo justified its shift in aspect ratio by adding some handy multitasking features. In this ColorOS 13.2 (based on Android 13), the new "Global Taskbar" offers an "App Library" button on the far left, which toggles a pop-up menu for quickly launching an app or even dragging it into a split-screen view. There's also a "File Pocket" button next to that, which is another pop-up menu showing your recent files, images and clipboard items, so that you can easily drag and drop into an active app.

Oppo

Another powerful multitasking feature is "Boundless View," which is basically split-screen on steroids. By tapping the top bar above your desired app in split-screen mode, you can click on "Expand View" which then automatically widens said app, but still leaving a small portion of the other app in view, thus letting you quickly swipe between apps. Similarly, you can also have up to three apps in this horizontal split-screen view — just drag the third app from the dock to the center of the screen. By expanding all three apps in this split screen, you'll be creating a "15-inch Boundless View" layout, and you can get an interactive overview with a four-finger pinch at any time. Much like the usual split-screen mode, you can save these Boundless View app combos for quick access on the home screen.

My favorite handy features from before, namely two-finger split screen (swiping down the middle of the screen) and "FlexForm Capture" (partly open the phone while in the camera app), are here to stay. As a bonus, Oppo promises four years of software updates and five years of security updates for the Find N3.

The Oppo Find N3, available in "champagne gold" and "classic black," will be rolling out to global markets soon, with pre-orders starting in Singapore on October 20th. The damage is S$2,399 (around US$1,745) which, to our surprise, is a big jump from the Find N2's price for the same 16GB RAM and 512GB storage configuration. The China version is offered as a premium kit, which is asking for 12,999 yuan or about US$1,777, and it comes with a kickstand case, a car charger and other accessories. Luckily for folks over there, they also have a more affordable 12GB RAM and 512GB storage variant for just 9,999 yuan (about US$1,367), but this is still a lot pricier than last year's base model. It'll be interesting to see how the supposedly near-identical OnePlus Open foldable — launching later today — will differentiate itself from its Oppo twin, be it pricing or software.

The ninth annual Google for India event had a big announcement: the company plans to manufacture its Pixel phones in India, following steady growth in the country's demand for the devices. Google's senior vice president for Devices and Services, Rick Osterloh, positioned India as one of the company's most important markets for Pixel devices. Google aims to begin rolling out locally produced Pixel 8 smartphones in 2024, eventually expanding to other Pixel models.

Google's contribution to the "Make in India" initiative will see partnerships with domestic and international manufacturers. In a tweet, the CEO of Alphabet and Google, Sundar Pichai, stated, "We're committed to being a trusted partner in India's digital growth." The pivot also allows Google to diversify its production away from China, where supply chain risks continue due to strains between the nation and the United States.

The company's decision is another win for India's government, which has attracted international device manufacturers, like Samsung and Apple, to make major investments in local production. Apple first produced iPhones in India back in 2017, but the first devices produced were all older models. Production initially also lagged six to nine months behind China but has improved steadily, first with iPhone 14 production starting within a month of launch. Most recently, a small number of India-made iPhone 15s were available in the region the same day as those produced in China. 

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to the factory floor whenever the line goes down. Day or night, weekends, vacations, whatever — when it breaks, the process engineer jumps.

The pressures of such a gig can be enormous, and seem to have weighed on [Tom Goff] enough that he spent a weekend building a junk bin analog signal generator to replace a loop calibrator that he misplaced. Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop. All that’s needed for both outputs is an Arduino and an LM358 dual op-amp, plus a few support components. The 0-10 V signal starts as a PWM output from the Arduino, with its 0-5 V average amplified by one of the op-amps set up as a non-inverting amp with a gain of 2. With a little filtering, the voltage output is pretty stable, and swings nicely through the desired range — see the video below for that.

The current loop output is only slightly more complicated. An identical circuit on a separate Arduino output generates the same 10 V max output, but a code change limits the low end of the range to 1 V. This output of the op-amp is fed through a 500-Ω trimmer pot, and the magic of Ohm’s Law results in a 4-20 mA current. The circuit lives on a piece of perf board in a small enclosure and does the job it was built for — nothing fancy needed.

And spoiler alert: [Tom] found the missing loop calibrator — after he built this, of course. Isn’t that always the way?

If you have a personal WhatsApp account and a business one — or two accounts of the same nature — you'll soon no longer have to carry two phones to be able to access them both. WhatsApp will finally let you add two accounts to one device, as long as you have a second phone number or a phone that supports eSIM or dual/multiple SIMs. 

You won't even need to log out of one account to be able to access the other. To have simultaneous access to two accounts, go to the app's Settings page and click on the arrow next to your name to find the "Add account" option. Each account has its own privacy and notification settings, so you can choose to receive alerts from one and not the other, which sounds incredibly useful if you're on vacation and don't want to hear from your work or business for a while. 

The new feature follows an update earlier this year that gave you the capability to access your account on multiple devices. WhatsApp used to be very strict when it comes to account access and limited you to having one account on one phone. It started exploring multi-device functionality in 2021, though, and rolled out the ability to sync one account across up to four phones in April. This upcoming update, which could make it easier to juggle different aspects of your life while maintaining boundaries, is rolling out for Android devices in the coming weeks.

Back in February, Meta launched a Telegram-like feature for Instagram called "broadcast channels," which introduced a one-way messaging feature to the app. It gave creators a way to update their followers without having to post on their main page. Now, the company is expanding broadcast channels' availability and is also bringing it to Facebook and Messenger. Creators and public figures with Facebook pages will now be able to send messages, including photos, videos and voice notes, to their community. 

It's still a one-way messaging tool, which means only Page administrators can send messages in the channel, but participants can react to them and vote in polls. Admins can launch a channel directly from their page, and Facebook will send their followers a one-time notification to join after they send their first message. Based on the screenshots shared by Meta chief Mark Zuckerberg, broadcast channels will show up in users' Messenger chats under a tab aptly labeled "Channels." Participants will get notifications every time the page owner sends an update, but they can mute the channel anytime. Presumably, those who chose not to participate the first time can still access the channel from the page's profile like people can on Instagram. 

Meta says any page admin where the feature is now accessible can start a channel if they want. The feature still isn't available everywhere, though, and those who can't find the option to open a broadcast channel yet can join the waitlist for now. 

The Chan Zuckerberg Initiative is opening a research center in New York City dedicated to developing new techniques for early disease detection and treatment. CZ Biohub NY, as it’s being called, will work with Columbia, Rockefeller and Yale universities to better learn how immune cells detect and attack specific diseases, and eventually use this insight to engineer cells that could do the job more precisely.

The charitable organization headed by Priscilla Chan and Meta CEO Mark Zuckerberg has committed $250 million to the effort, according to STAT, alongside investments of $10 million each from the State of New York and New York City. In a blog post announcing CZ Biohub NY, the Chan Zuckerberg Initiative said it will start by focusing on cancers and other diseases that often go undetected until they’ve advanced to the point of being difficult or impossible to treat. That includes “ovarian and pancreatic cancers; neurodegenerative diseases, including Parkinson’s and Alzheimer’s; as well as aging and autoimmunity,” CZI says.

CZ BioHub NY aims to get to the bottom of how immune cells work, down to their ability to spot tissue-specific changes that can be among the earliest indications of a disease’s onset. Then, its researchers hope to be able to create cells that can sniff out these abnormalities even earlier than they’re currently able, and be sent to the disease sites directly for more effective treatment. These bioengineered immune cells would “scout, report, and repair damage to our cells before it leads to serious illnesses,” said Chan.

The New York hub is the latest in CZI’s growing network of research institutions, and joins three others that have been established in San Francisco, Chicago, and Redwood City. All have pledged to break ground on their respective scientific goals within a time frame of 10-15 years. Now, according to STAT, the New York biohub just needs to secure a site to work out of.
