Apple Music does not work on lossless airplanes, only space audio with Dolby Atmos

Apple announced in June that it would be offering support for Dolby Atmos with Apple Music Lossless Music and Space Audio. However, there is some confusion as to which devices can take advantage of these features, especially the high reliability available in the music service. Apple has left information about these technologies and requirements Airports and Airboats Max and HomePots are leaving HiFi. However, the headphones will have support for space audio and Dolby Atmos.

To take advantage of the high reliability offered by the company, wireless headphones are immediately phased out by Apple or a third party.

Apple Music delivers high fidelity sound

Lossless option may be available in settings for headphones, but this feature is not supported via Bluetooth. Thus, airports in relation to lossless have already been abandoned.

Now, there is still skepticism on the Airboats Max because they can be connected to the lightning cable with a 3.5mm connector. OK, but Apple also marked the site 9to5 “Airboats Max does not currently support digital audio formats in wired mode.” For Airbus owners, the only feature compatible with Apple Music is Space Audio with Dolby Atmos.

What is the reason why airports do not support lossless?

First we need to read what Apple described Its release communication In these new technologies. You can read the following:

Apple Music also offers a list of over 75 million songs on Lossless Audio. Apple uses the ALAC (Apple Lossless Audio Codec) to protect every bit of the original audio file. This means that Apple Music subscribers can hear the same thing created by artists in the studio.

To start listening to lossless audio, subscribers using the latest version of Apple Music can enable it Definitions > Song > Audio quality. Here, you can choose different settings for different connections like cell phone, wifi or download.

Apple Music starts at CD quality, which goes 16 bit at 44.1 kHz (kHz), and goes up to 48 kHz at 24 bits, which is native to Apple devices. As for the actual audio file, Apple Music also offers high-resolution lossless up to 24 bit at 192 kHz.

Therefore, a typical Apple Music track encoded in AAC with a 256 kbps bit rate is not considered “studio quality”, but is sufficient for most users with normal headphones. With Apple Music Lossless, users can listen to songs encoded in ALAC encryption starting at 16 bits / 44.1 kHz, also known as “CD quality”.

The quality of the audio file on a CD is about 1411 kbps, which is much higher than the normal Apple Music AAC file. This number is even higher when it comes to Apple Music Hi-Res Lossless, which requires even better equipment – such as an outdoor DAC. The higher the bit rate, the more details will be in the music, which means the audio has passed the lower compression.

What is DAC?
DAC stands for Digital First Analog Converter. A DAC receives digital audio information and converts it into an analog signal. This signal goes to an amplifier and then to the transceiver.

Lossless Bluetooth picture and headphones

But does Bluetooth not support lossless?

It is true that Bluetooth technology can theoretically reach speeds of up to 2000kbps, but this requires better visuals and conditions. Therefore, in the real world, as the Bluetooth signal travels through the air, it is necessary to consider the normal interference and distances that reduce bandwidth.

These conditions prevent wireless work on any Bluetooth headset. Note that this limit is not limited to Apple Music and Apple headphones.

Apple could develop a lossless codec compatible with Bluetooth and Sony’s LDAC, which can reach up to 990 Gbps – but the company has yet to announce new models of airports to support a new codec.

In short

The hardware required for each new Apple Music feature is:

  • Lost: A wired headset (except Airboats Max with Lightning / 3.5mm cable)
  • Hi Res Lossless: Wired headset connected to external DAC
  • Space Audio: Any Airboats or Beats model with Apple’s W1 or H1 chip (Apple claims that users can manually enable this option for other headsets)

What about homepages?

According to Apple, Apple Music does not work with Loseless Homepot or HomePot Mini. Additionally, in the case of space audio, this feature is also available on compatible Mac computers.
