Apple Lists FLAC Audio Playback Support for 4K Apple TV, iPhone 7, iPhone 8, iPhone X

by

Apple has quietly included support for playback of FLAC audio files on the 4K Apple TV, iPhone 8, and iPhone X, with compatibility also added retroactively to the iPhone 7 when iOS 11 gets its public release.

Support for the lossless compression codec now appears in the technical specifications on Apple's website for all of the above devices. However, as it stands, Apple's Music app does not currently support the format, so device owners who want to listen to the higher quality audio files will have to use the native Files app or a third-party app specifically made for FLAC playback, such as VLC or Plex.

Apple's support for the FLAC codec doesn't officially extend to the iPhone 6s or iPhone SE, which may be because an A10 processor is a minimum requirement for hardware decoding and Apple is not satisfied with the power consumption tradeoffs of FLAC software decoding.

That said, Apple's latest iPad Pro range should also be capable of FLAC playback thanks to their high performance A10X Fusion chips, yet Apple hasn't updated its iPad Pro tech specs to indicate they will also support the standard.

It's possible that Apple is still testing FLAC support for its range of mobile devices, and may even have plans to offer the lossless compression standard as a download option in iTunes and playback in the Music app further down the line. However, it's worth noting that mobile users would only get the full benefits of FLAC by listening using Lightning-connected wired headphones, since a Bluetooth audio connection doesn't offer enough bandwidth to make the experience worthwhile.

You can play HD Audio over Bluetooth. And it sounds great.

HD FLAC files sound brilliant. I'm considering the Note 8 as it has 1-bit audio playback as well. Have a bunch of DSD audio files. Does it make a difference? Certainly a hell of a lot better than AAC or MP3.

I have these BT headphones for my S7 edge that playback 24bit 96khz audio over Bluetooth, so it can be done. Just needs a proprietary codec (Samsung UHD over Bluetooth) or Qualcomm AptX HD

Peerless UHQ Sound
Enjoy superb UHQ audio with the Samsung Level On Wireless Pro – even better sound than CD quality audio. Using UHQ-BT codec technology, the Level On Wireless Pro allows you to enjoy a richer and more balanced audio experience with authentic-sounding, UHQ sound.

Alas, over Bluetooth, an iPhone, which doesn't have Apt-X compatibility, will re-compress anything that's not AAC to SBC, which sounds like absolute crap. For instance, Spotify - even in "Extreme" 320kbps Ogg Vorbis, sounds vastly inferior to Apple Music @256kbps AAC, because the iPhone sends raw AAC over bluetooth to compatible headphones, whilst it recompresses the OGG on Spotify into SBC.

The only solution I've found to use my Spotify subscription over Bluetooth in a decent quality is to use a cheap Android phone with Apt-X...

By the way, all those Bluetooth 5 bells and whistles will change nothing.

we must assume that Bluetooth audio is still sent from iPhone 7 to Airpods, or any other Bluetooth headphone, using AAC – Apple’s ‘own’ lossy codec of choice. In theory and reality this diminishes the listening experience when directly compared to an aptX-piped Bluetooth pairing.
iOS only uses AAC over Bluetooth for content that is already encoded in AAC: Apple Music and songs bought on iTunes. Any other codec (Spotify's OGG, Deezer or Amazon's MP3, Anghami's Dolby Pulse, Qobuz's ALAC, Tidal's MQA...) is re-compressed using the inferior SBC codec, which is more battery-efficient but more lossy. As a result, you get double the compression artifacts and the soundstage is reduced to nothing.

Lack of FLAC support has never been much of a big deal for me because both FLAC and ALAC are lossless and you can convert between them.

Any FLAC content I acquire gets transcoded to ALAC and I delete the FLAC files. Should I want FLAC in the future I can just transcode it back. That's what's great about lossless formats.

Just convert FLAC to ALAC, folks. It works natively on iTunes, plays back on hardware ranging all the way back to the first iPods, and the compression ratio is very similar. There's also plenty of free tools to do it, including ones that'll parallelize the conversion of many files to do it quickly on multi-core CPUs.

Slightly off topic but it’s inexcusable that AirPlay can’t even stream 48 KHz which is the standard frequency for TV/Cinema. It sends 44.1 kHz instead, the standard for audio CDs and music. Some will argue there’s no way you can tell the slight reduction but I argue there’s no reason they can’t send it in its native encoding quality! It’s a pretty minor increase in bit rate and still well within spec, even for slow Wi-Fi!

Can anyone confirm this is still the case with AirPlay 2?

I re-ripped all my music to Apple Lossless years ago but would have preferred FLAC as my understanding is that's it's an open standard compared to AL. So is this going to be an option in iTunes from here forward (rip in FLAC) or have I misread/misunderstood?
ALC is open-source as well, although it has less support in the open-source community.
