Takes some real motivated reasoning to believe Israel needed to bomb hospitals.

Apple’s AI-driven Stem Splitter audio separation tech has hugely improved in a year

2 Shares

Imagine that you have a song file—drums, guitar, bass, vocals, piano—and you want to rebalance it, bringing the voice down just a touch in the mix.

Or you want to turn a Lyle Lovett country-rock jam into a slamming club banger, and all that's standing between you and the booty-shaking masses is a clean copy of Lovett's voice without all those instruments mucking things up.

Or you recorded a once-in-a-lifetime, Stevie Nicks-meets-Ann Wilson vocal performance into your voice notes app... but your dog was baying in the background, and your guitar was out of tune. Can you extract the magic and discard the rest?

Without access to the original recording project files or master tapes, jobs like these have always been slightly difficult. Specialized tools or software could extract specific sounds, often the vocals, sometimes through crude techniques based around high- and low-passing the audio, but the results were never quite what one might wish. With the advent of machine learning, however, computers have gotten scarily good at reaching into dense audio mixes and surgically extracting complicated parts.

Apple's May 28 update to its flagship audio program, Logic Pro, shows just how far this tech has come—and how quickly it's advancing.

Put to the test

In 2024, Apple rolled out the Stem Splitter feature in Logic 11. Powered by AI tools and requiring Apple Silicon in order to work, Stem Splitter could "recover moments of inspiration from any audio file and separate nearly any mixed audio recording into four distinct parts: Drums, Bass, Vocals, and Other instruments, right on the device," Apple said. "With these tracks separated, it’s easy to apply effects, add new parts, or change the mix."

And it worked—but it worked best as long as you kept all the stems together (that is, if you simply rebalanced the track or added effects to one of the stems). But if you wanted to isolate a single stem, you had to contend with some fairly gnarly audio artifacts.

Consider an example from a song I've been working on. Here's a snippet of the full piece:


After running Logic's original Stem Splitter on the snippet, I was given four tracks: Vocals, Drums, Bass, and "Other." They all isolated their parts reasonably well, but check out the static and artifacting when you isolate the bass track:



The vocal track came out better, but it was still far from ideal:


Now, just over a year later, Apple has released a point update for Logic that delivers "enhanced audio fidelity" for Stem Splitter—along with support for new stems for guitar and piano.

The difference in quality is significant, as you can hear in the new bass track:


And the new vocal track, though still lacking the pristine fidelity of the original recording, is nevertheless greatly improved:


The ability to separate out guitars and pianos is also welcome, and it works well. Here's the piano part:



Pretty impressive leap in fidelity for a point release!

There are plenty of other stem-splitting tools, of course, and many have had a head start on Apple. With its new release, however, Apple has certainly closed the gap.

Izotope's RX 11, for instance, is a highly regarded (and expensive!) piece of software that can do wonders when it comes to repairing audio and reducing clicks, background noise, and sibilance.

It includes a stem-splitting feature that can produce four outputs (vocal, bass, drums, and other), and it produces usable audio—but I'm not sure I'd rank its output more highly than Logic's. Compare for yourself on the vocal and bass stems:



In any event, the AI/machine learning revolution has certainly arrived in the music world, and the rapid quality increase in stem-splitting tools in just a few years shows just what these AI systems are capable of when trained on enough data. I remain especially impressed by how the best stem splitters can extract not just a clean vocal but also the reverb/delay tail. Having access to the original recordings will always be better—but stem-splitting tech is improving quickly.

Speaker Emerita Melissa Hortman, husband shot and killed; Sen. John Hoffman and wife also shot - KSTP.com 5 Eyewitness News

1 Share

Democratic House Speaker Emerita Melissa Hortman and her husband, Mark, were shot and killed Saturday morning at their home in Brooklyn Park in what Gov. Tim Walz called a “politically motivated assassination.”

During a news conference Saturday morning, the governor also confirmed that DFL State Sen. John Hoffman and his wife, Yvette, were also shot multiple times at their home in Champlin. They were both out of surgery, and Walz said he was “cautiously optimistic” about their chances of survival.

“Our state lost a great leader, and I lost the dearest of friends. Speaker Hortman was someone who served the state of Minnesota with grace, compassion, humor and a sense of service,” Walz said. “She was a formidable public servant, a fixture and a giant in Minnesota. She woke up every day determined to make this state a better place. She is irreplaceable and will be missed by so many.”

Authorities say both lawmakers and their spouses were shot by a gunman impersonating a police officer. A manhunt is underway in Brooklyn Park for the person responsible, and thousands of people in the surrounding area remain under a shelter-in-place order.

Minnesota Bureau of Criminal Apprehension Superintendent Drew Evans said police first responded to the shooting at the Hoffman residence in Champlin around 2 a.m. At 3:35 a.m., a call came in of a similar attack at Hortman’s home in Brooklyn Park.

Brooklyn Park police were “proactively checking” on Hortman’s home due to her close proximity to Hoffman. Evans said those officers encountered the suspect, who fired at them. Police returned fire, but the gunman got away.

Hortman was first elected to the Minnesota House of Representatives in 2004, and she served as House speaker from 2019 to 2025. She and her husband are survived by their two children.

GOP Rep. Lisa Demuth of Cold Spring succeeded her as House speaker during the 2025 legislative session under a power-sharing agreement in a tied chamber. In a written statement, she condemned the attack on her colleague.

“I am horrified by the evil attack that took place overnight, and heartbroken beyond words by the loss of Speaker-Emerita Melissa Hortman and her husband Mark,” Demuth said. “With the law enforcement response ongoing and details still emerging, I will simply ask all Minnesotans to please lift up in prayer the victims of this horrific attack, as well as the law enforcement personnel still working to apprehend the perpetrator.” 

Sources tell 5 EYEWITNESS NEWS that all other Minnesota state lawmakers are under protective custody in coordination with the Minnesota Department of Public Safety and local law enforcement jurisdictions.

Two Days Talking to People Looking for Jobs at ICE | Online Only | n 1 | Yanis Varoufuckice

1 Share

On Thursday and Friday of last week I attended a Department of Homeland Security job fair at the Dulles Expo Center in Chantilly, Virginia. I learned about the event while browsing the DHS website in order to find the phone number of someone who’d been detained by ICE. A pop-up ad linked to an EventBrite page, with free tickets readily available.

Customs and Border Patrol, the Coast Guard, and the Secret Service were all recruiting at the event, but ICE was the main draw. Far more applicants stood in line to submit their resumes for deportation officer than for any other position on offer in the cavernous room.

Naturally there were a large number of law enforcement types hanging around the convention—men with military fades, moisture-wicking shirts, and tattoos of the bible and the constitution and eagles and flags distended across their arms. But there were also a handful of women ICE applicants and a lot of men of color. The deportation officer applicant pool was, I felt, shockingly diverse—one might say it looked like America. The whole place looked and felt like America.

There were tactical trucks, motorcycles, and drones; an ambulance, a Humvee, and a kind of paddy wagon that could accommodate eighty or ninety people, all parked inside the Expo. At rest in curtained-off and carpeted recruitment areas, they loomed over the supportive agency staffers there to “triage” resumes and offer encouragement to prospective employees. The ICE recruitment area sported two enormous trucks similar to those used to menace protestors in Los Angeles. When an agent lifted the curtain, I saw piles of Starbucks tumblers hidden behind their wheels.

At the CBP booth, a glowing snowmobile was parked next to a teepee made of synthetic fabrics and metal poles where applicants could sit and charge their phones. Some of them looked a little frightened, less tough than people in the photographs around them, the diverse officers framed in siren lights, shot from below to emphasize their solemnity and certainty of purpose. The recruiter for the air marshals told a crowd of applicants they shouldn’t bother applying if they were fat. “No one likes a fat cop,” she said. She drank Pink Monster Ultra Rosá and had multiple dreamcatcher forearm tattoos.

She told us not to apply if we couldn’t do pushups and sit-ups, or if we were unprepared to run one and half miles. Candidates who “punched their girlfriend or boyfriend” also need not apply, she said. But candidates should also show empathy and emphasize what was unique about them in interviews. “Maybe you saw a car on fire in Colorado and you threw blankets onto it. That’s great. Say you were on a SWAT team in Albuquerque. That’s also great,” she said.

The air marshals were the only group to have a dedicated, detailed presentation—the rest relied on pre-recorded talks or videos. CBP’s video looked like it was made by professionals—ICE’s, with its “Stencil” font titles and royalty-free photographs of stainless steel, had the feeling of a grade-school history project, the kind that little boys use as an excuse to shoot each other with Airsoft guns.

The ICE video began with jittery, sepia-toned photographs of the founding fathers and the Federalist Papers, jumped ahead to immigrants arriving at Ellis Island, and from there to mugshots of the 9/11 attackers. Though the narration was inaudible, I believe that 9/11 was cited to justify the deployment of the men who appeared onscreen next, the ICE agents arresting meatpackers with their hairnets still on.

A solitary fascist marched through the center of the frame even as the setting changed around him—from secondhand store, to airport, to warehouse. He was everywhere, protected by his flak vest and holstered pistol.

The banality of these settings juxtaposed with the grandiosity of mission reminded me of a TikTok I had seen recently, which compared the way men and women move through the world. In the video a couple walks through a mall while a series of subtitles announce their divergent thoughts. The man, ever on his guard, sizes up the threat posed by each passerby, commenting to himself, “I can take him,” “I can take him,” or “I’d need backup,” depending on the size of the individual in question. The woman just examines the shop windows, thinking things like “That’s so cute!” or “I wish I could buy that.”

Although obviously unrealistic as a way of experiencing a mall, the video suggested that populating one’s field of vision with imaginary threats might offer a sense of purpose, which life in suburban America does not always provide.

One of the ICE applicants I spoke with seemed to have an insatiable desire for conflict in line with this hypothesis. All his life, he said, he had hoped to fight wars in Iraq or Afghanistan. He’d joined the army hoping to fulfill this desire. But our foreign wars had wound down by the time of his enlistment, and he never got a chance to fight abroad.

He said his wife had almost been assaulted in Texas, and when she’d called the police they arrested a man who turned out to be an “illegal alien” and who was promptly deported. He said he’d seen videos of a member of the Taliban getting into an argument at a fast-food restaurant in California (I couldn’t find any evidence of this—not even as a conspiracy), and that he wanted to join ICE to protect his family.

“I learned all these skills in the army—smash and grabs, site exploitation—and never got to use them,” he said. “So I’m here to kind of do what I learned to do over there, but this time here, defending my country.”

Previously impressed by the connections between war and domestic policy elucidated by the historians Kathleen Belew and Stuart Schrader, I found this man’s account almost embarrassingly transparent. This was the most straightforward articulation I’d ever heard of someone bringing the war home.

Other applicants offered similar explanations for their motives.

There was the young, taciturn southerner managing a batting cage near New Orleans, and the pimply youth from Kentucky, churning out Yahoo Finance content for twenty dollars an hour. Both said they were tired and bored. The latter said his father had been in ICE, but he “didn’t really know what he did.”

I spoke to a gregarious New York police officer who was fed up with patrolling Times Square and all “the savages” there. Another applicant said he was sick of installing office furniture in properties subleased by the United States Marines.

A blind man I spoke to, who was hoping to find a data-centric position with ICE, said he was sick of his current job collecting child support payments from delinquent parents. At present, he said, his “hands were tied” because the law in his state forbade him from sending in sheriffs to collect money from deadbeat dads. In a lilting, basso voice, he told me that “in college, I wrote several papers about the harms of illegals in America.”

The last applicant I spoke to said he didn’t care much about the politics of ICE—it was just that he thought his taxes shouldn’t be used to buy school supplies for “illegal alien children.” What he was really interested in, he said, was parlaying his wages as a deportation officer into buying Airbnbs. “My classmates came up in the same environment as me,” he said, “but now they’re off posting photographs of Lamborghinis on Instagram, standing on balconies of waterfront apartments.”

His dad had also been in ICE and had broken down the doors of a Queens family that had just sat down to dinner when he stormed in. They all happened to be wearing Obama shirts and hats and were eating off of Obama dishware. Once, in the early part of his career, the man had gotten to travel to Southeast Asia on various deportation flights and had sent his son photographs of a beautiful waterfall in Cambodia. “I was like, what the fuck dad?” the young man said. “I thought you were supposed to be deporting people!”

The prospect of travel excited this applicant. And in fact over and over the DHS agents at the fair emphasized how it was the best part of their job.

A longtime ICE agent said he had accompanied undocumented immigrants on deportation flights to more than fifty countries and stayed in numerous three- and four-star hotels. A White House rooftop sniper said that she had had “amazing experiences in foreign countries” and that the camaraderie of her sniper team reminded her of her college volleyball team.

A CBP agent in Arizona said his favorite part of the job was riding horses through the mountains. The staff of the EMT Hazardous Agent Mitigation & Medical Emergency Response team (Hammer) said that he traveled with his ambulance all over the world, loading it into massive C17 airplanes and then sleeping beside it midair. He said it was “almost like camping.”

The motivating force behind American career fascism would appear to be wanderlust. My conversations with prospective Enforcement and Removal Operation officers tended to follow the familiar script of engagement with the most banal people on Tinder, the kinds of people who post airplane emojis in their bios. Granting that the banality of evil, as an explanation, has itself become banal, it was hard to know what else to make of all this. The US is filled with “pretty nice guys” who are ready to inflict, who have already inflicted, senseless and life-shattering violence on innocent, impoverished people.

I went outside for about an hour and found a small bench next to a manmade lake just beyond the expo parking lot. The lake was filled with geese diving for food in the water, then bobbing up, heads covered in mud and weeds.

Looking behind me, I realized that that the body of water was connected to the local offices of Northrop Grumman, which supplies Israel with the Longbow missile delivery system for its Apache attack helicopters, and laser weapon delivery systems for its fighter jets. Across the highway was an enormous company headquarters called BigBear AI, which, as it turned out, was yet another defense contractor, lately being sued for defrauding investors.

This is a disgusting country, I thought, irredeemable visually, psychically, morally, and ethically, and whatever is likable about our people’s warm patter does not in any way forgive what we have done to the world. Furthermore, it isn’t hard to bring politeness and evil into view at the same time.

I could not bring myself to return to the convention. I walked and walked. I bought some food at a Walmart and then spoke to a man in the parking lot who had sawed a square hole into the trunk of his truck and inserted a window-unit air conditioner inside of it and attached the A/C to a generator. His clothes were drying on the ground.

“Is your car’s A/C broken?” I asked. “Yep!” he replied, in a cheerful voice. “It’s broken!”

In the Uber on the way home I had a rambling, incomprehensible conversation with a man who told me that working at a car dealership was harder than fighting in a war and that he had the facts to prove it. He said that his ex-manager had been trained to jump out of airplanes but had had a heart attack because of how hard it was to sell cars in Virginia. After this he added, for no reason, “I’m a normal person. When I go to Walmart, I look for the beer in the exact middle of the price range.”

Back at the convention the next morning, a Border Patrol agent was walking the agency’s emotional support dog around the conference perimeter. Her name was Willow, her handler said, and she was 5 years old.

She was giant and soft, with impeccable fur, and had already flown to sixteen different countries. She belonged to a special, docile German breed called the Leonburger and her job was to confer warmth to Border Patrol agents on the verge of committing suicide. She would work as long as she wanted to work and was hungry for lunch, the handler said.

Willow’s presence elicited coos of sympathy from agents whose job it is to impart unshakeable traumas onto the wretched of the earth. This same sympathy was later extended to a disturbing Department of Defense “BigDog” robot named Confidence, whose handler directed it to waggle its hips and peer up inquisitively at onlookers. Its thin frame resembled a miniature fuselage with imitation deer legs attached to the bottom. Its hooves looked like the wheels of an office chair, and it had a spinning camera on top of its ass.

Apart from its dog-like face, there was nothing creaturely about it, and even this mild resemblance soon disappeared. A DHS agent placed a BODYARMOR SuperDrink on the ground and the dog retrieved it by opening up its entire face to become a mechanical claw.

Back at the ICE booth, a lone protester was at last present, asking a simple question. At the deportation officer recruiting table, he asked the agent, “Have you read Eichmann in Jerusalem?”

“Do you know what the Nazis said?” he asked. “They said they were just following orders. How do you think of your own work in this context?” He pressed ahead: “I’m just trying to figure out if this position is right for me. Do you think it’s right to separate people from their families, their mothers and fathers from their children, hard-working people who pose no threat? Do you think that’s right?”

The agent demurred, turned away. She looked shy and frazzled. He asked her again, “Have you read Eichmann in Jerusalem?” But at this point another agent—a thick-necked, red-faced pig—walked up to the protester and leaned into his face in an effort at intimidation. I am not certain I heard the next part correctly, but I think the man hissed: “Eichmann in WHAT?”
