tvOS 27 Brings Hi-Res Lossless Audio to Apple TV 4K via Apple Music
Apple has long been pushing the boundaries of audio quality through its streaming platform, and with the arrival of tvOS 27, the company is taking a significant leap forward for home listening enthusiasts. Apple Music subscribers can now look forward to Hi-Res Lossless Audio on Apple TV 4K, delivering studio-quality sound directly through their living room setup. This is a meaningful upgrade that audiophiles and casual listeners alike have been waiting for, and it signals Apple's continued commitment to making premium audio accessible to everyone in its ecosystem.
What's New in tvOS 27 for Apple Music?
The headline addition in tvOS 27 for Apple Music users is full support for Hi-Res Lossless Audio playback. While Apple TV 4K has supported standard Lossless Audio since tvOS 26 — at up to 24-bit/48 kHz — it notably stopped short of supporting Hi-Res Lossless, which covers audio above 48 kHz and up to 24-bit/192 kHz. With tvOS 27, that ceiling has been raised dramatically.
According to Apple, subscribers who have compatible external speaker outputs connected to their Apple TV 4K will be able to enjoy their favorite songs at the highest audio quality the platform can deliver. The company describes the experience as "studio-quality sound," positioning the Apple TV 4K as a serious contender in the home audio space — not just a streaming box, but a high-fidelity audio hub for your living room.
Understanding Lossless vs. Hi-Res Lossless Audio
To appreciate the significance of this upgrade, it helps to understand the difference between standard Lossless and Hi-Res Lossless Audio.
What Is Lossless Audio?
Lossless audio refers to a method of audio compression that preserves all of the original data from the source recording. Unlike the lossy formats most streaming services have historically relied upon — such as AAC or MP3 — lossless formats do not discard any audio data during encoding. The result is a file that is bit-for-bit identical to the original studio master. Apple Music uses ALAC (Apple Lossless Audio Codec) for its lossless tier, which delivers CD-quality audio at 16-bit/44.1 kHz up to 24-bit/48 kHz.
What Is Hi-Res Lossless Audio?
Hi-Res Lossless Audio takes things a step further. It refers to lossless audio files that exceed standard CD quality, typically starting above 48 kHz and going up to 24-bit/192 kHz. At this resolution, the audio contains more data than a standard CD track, capturing finer details in timing and dynamic range. Whether the average listener can perceive the difference in a real-world environment is a topic of ongoing debate among audio experts, but for enthusiasts with high-end speaker systems, the improvement can be noticeable and meaningful.
It's worth noting that Apple itself acknowledges the debate. The company states that while lossless compression preserves all original data and can result in an improved listening experience, the extent of that improvement varies. That said, for users with the right equipment, accessing the highest available resolution is always preferable to having it artificially capped.
What You Need to Take Advantage of Hi-Res Lossless on Apple TV 4K
Not every Apple TV 4K setup will automatically benefit from this upgrade. Apple specifies that subscribers will need compatible external speaker outputs to experience Hi-Res Lossless Audio. This means connecting your Apple TV 4K to a capable audio system — such as a high-quality stereo receiver, a DAC (digital-to-analog converter), or a compatible soundbar that supports high-resolution audio passthrough.
- Apple TV 4K (any supported model): Hi-Res Lossless playback requires a current Apple TV 4K running tvOS 27.
- Compatible external speakers or audio receiver: The connected audio output device must support high-resolution audio to benefit from the full 24-bit/192 kHz signal.
- Active Apple Music subscription: Hi-Res Lossless Audio is part of the standard Apple Music subscription at no additional cost — a notable advantage over some competitors.
- Appropriate cabling: Using a high-quality HDMI or optical connection to your audio hardware will ensure the signal is passed through without degradation.
Without compatible external hardware, the Apple TV 4K will continue to deliver the best audio quality its output allows, but the full Hi-Res Lossless experience will require that additional investment in your audio chain.
How to Install tvOS 27 and Try It Now
If you're a registered Apple developer, you don't have to wait until fall to experience this upgrade. The tvOS 27 developer beta is already available. You can install it directly on your supported Apple TV by navigating to Settings → System → Software Update → Beta Updates and selecting the developer beta channel. As always, beta software may contain bugs and is best installed on a secondary device rather than your primary home theater setup.
For everyone else, tvOS 27 is expected to be released to the general public in the fall of 2026, in line with Apple's typical annual software release schedule alongside new iPhone and Apple Watch models.
Why This Upgrade Matters for the Apple Ecosystem
Apple has been steadily building out its high-quality audio infrastructure across its devices and services. Since introducing Lossless and Spatial Audio to Apple Music in 2021 at no additional charge, the company has been working to bring those formats to every corner of its product lineup. The Apple TV 4K was one of the remaining gaps in that coverage, particularly at the Hi-Res tier.
This upgrade reinforces the Apple TV 4K's value proposition as more than just a video streaming device. Paired with a quality audio system, it now becomes a capable Hi-Res music player that can serve as the heart of a high-fidelity home audio setup — all controlled through the Apple Music app and the familiar tvOS interface. For users who are already invested in the Apple ecosystem, it's a compelling reason to route their music listening through the Apple TV 4K rather than a separate dedicated streamer.
The Bottom Line
tvOS 27 delivers a genuinely meaningful upgrade for Apple Music subscribers who care about audio quality. By extending support from 24-bit/48 kHz all the way up to 24-bit/192 kHz Hi-Res Lossless playback, Apple is closing the gap between the Apple TV 4K and dedicated high-fidelity audio streamers. Whether you're a committed audiophile or simply someone who wants the best possible sound from their living room system, this is the kind of incremental but impactful improvement that makes upgrading to tvOS 27 well worth it when it arrives this fall.
