What Is Lossless Audio, and Do You Really Need It?

What Is Lossless Audio, and Do You Really Need It?

There’s a difference, of course, between “putting some music on” and “listening to music.” The first is just a nice way of disturbing the silence while you get on with some task or other, while the second is a way of transporting you into a world of emotion and expression. And so it follows that while the first doesn’t require an exceptional level of quality to be effective, the second benefits no end from sounding as close to the artist’s original intentions as is possible. For digital music, that’s lossless audio.

You may have heard more about lossless audio recently, thanks to a growing number of music streaming services offering it as part of their subscriptions, most recently Spotify. But what exactly is lossless audio, how do you get it, and does it really make a difference? Let’s get into it.

What Is Lossless Audio?

At the risk of stating the obvious, lossless audio is digital audio that has lost none of the information originally contained in the recording. This doesn’t mean it hasn’t been compressed—both lossless and “lossy” files will have been through a process of compression in order to make sure the digital file is of manageable size to be streamed reliably. It’s the size of the file after that compression that defines whether it’s lossless or not—and there are two numbers that are relevant here.

First is the “sample rate,” which is the number of times per second the analog audio signal is examined as it’s being converted into digital information. The higher the sample rate, the more accurate the digital information should be—a compact disc has a sample rate of 44.1 kHz, for example, which means the analog signal is sampled 44,100 times per second as it’s being converted to digital.

Next, there’s “bit depth,” which signifies how much of the analog sound wave each sample of the signal is capturing. The higher the number here, the more of the analog audio signal is being examined, and the more accurate the transcription of the information from analog to digital. It also helps deliver greater dynamic range, which is the distance between the quietest and the loudest moments in a recording. Compact disc uses 16-bit audio.

The 16-bit/44.1 kHz resolution that compact disc uses was acknowledged at the time of the technology’s development as the best compromise between capturing as much data as is audible to the human ear as possible and keeping digital audio files down to a manageable size. And it has endured—any digital audio file with a resolution of at least 16-bit/44.1 kHz can be described as lossless, as long as it’s stored in a lossless format like FLAC (Free Lossless Audio Codec) or, indeed, on a compact disc. Anything less than this—often expressed differently, in kbps—can safely be termed “lossy,” while anything larger takes us into the realms of “high-resolution” audio (which is ultimately anything higher than CD quality, but generally it’s considered as anything with a 24-bit bit depth or above).

Is Lossless Audio Better Than Regular Audio?

Short answer: yes. Information is knowledge, after all, and knowledge is power—or, in this instance, knowledge is access to as much audio information as possible, which keeps your music sounding as the artist intended.

The slightly longer answer: yes, as long as you’re using equipment capable of revealing all of the information contained in a lossless audio file, then it will sound better* than the lossy equivalent. This means everything from your source of music, how well the digital information is converted to analog, its amplification and, finally, the speakers or headphones that serve it to your ears.

Even with the campaign, getting qualified individuals through training and into the role may still be a challenge: according to the Department of Transportation’s Office of Inspector General (OIG), the FAA is facing “considerable challenges with training, including a shortage of qualified instructors, training capacity limitations, an outdated curriculum, and high training failure rates.”

An FAA video full of clips of things like Madden NFL, Fortnite, League of Legends esports, and the Xbox One stinger from commercials promises an average salary of $155,000 per year after three years and says that “you’ve been training for this.”

In a press release, the FAA says that air traffic controllers said in exit interviews that gaming was an influence on “their ability to think quickly, stay focused, and manage complexity.” The FAA’s website about the application process encourages applicants to “level up” their career. However, the Trump administration isn’t the first to target gamers for the role; according to The New York Times, the Biden administration launched a “Level Up” recruiting push in 2021, encouraging gamers as well as women and members of minority groups to become air traffic controllers.

Getting more air traffic controllers has been a focus for Sean Duffy, President Trump’s secretary of transportation, and he announced a plan to “supercharge” hiring shortly after he was sworn in for the job last year. That campaign closed in March 2025 and “attracted more than 10,000 applications,” resulting in about 600 trainees entering the Controller Training Academy, the OIG says. And the GAO says that some attrition during the air traffic controller hiring process “may be preventable,” noting that the hiring process can be “difficult to navigate” and that applicants may have already accepted other jobs by the time they get an employment offer.

The National Air Traffic Controllers Association (NATCA), the union representing air traffic controllers, “welcomes innovative approaches to expanding the candidate pool,” including “outreach to individuals with high-level aptitude skills such as gamers,” according to a statement from NATCA president Nick Daniels.

After 10 days, the four astronauts aboard the Orion spacecraft have returned to Earth, their mission around the Moon a success.

Integrity, the name of the crew’s spacecraft as part of NASA’s Artemis II mission, splashed down in the Pacific Ocean off the coast of San Diego, California, at 5:07 p.m. Pacific Time, according to NASA. The four crew members aboard — three Americans and one Canadian — were all in “green” (or safe and healthy) condition after the Orion craft’s “perfect” landing.

The crew was composed of Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen. From liftoff to splashdown, the quartet was in space for just over nine days (with NASA rounding up and calling it a 10-day mission).

Artemis II was NASA’s first mission to the Moon’s orbit in more than 50 years. The crew traveled farther from Earth than humans ever have before — reaching an estimated 252,760 miles from our planet. During their journey, the crew orbited the Moon, taking photos from their flyby of never-before-seen parts of the surface, and even witnessing a total solar eclipse. They identified new craters, naming one after Wiseman’s wife Carroll, who died of cancer in 2020.

“These were the ambassadors to the stars that we sent out there,” Jared Isaacman, NASA’s administrator, said after the landing. “I can’t imagine a better crew. It was a perfect mission.”
