Engadget Logo Entered Japanese version of AirPods Max cannot support Apple Music's lossless regeneration

The fact that Apple Music announced the distribution with loseless sound quality has delighted music fans who were faintly dissatisfied with their sound quality.This is the same as the CD from the CD from June..From 1kHz/16bit music, you will be able to enjoy a maximum of 192kHz/24bit lossless or high -resolution sound sources.

However, Apple explains that a high-resolution-compatible regeneration environment such as USB-DAC requires a roseless playback of a 48kHz/24bit sound source.

On the other hand, Apple did not explain clearly that the existing Apple wireless headphones, earphones, and speakers do not support the playback of lossless streaming.Considering the music fans who purchased an AirPods Max of 67,980 yen including tax, it is a disappointing story.

The audio data included in the CD is a linear PCM method, and the audio of the analog is sampled rate 44.Digitized with 1kHz, bit depth (number of quantization bits) 16bit.The sampling rate is a number that shows how many times the sound is converted to digital per second, or the bit depth is how many posters (strength) of the sound (strength).The greater these numbers, the more they can digitize them closer to the sound of reality.

And high -resolution sound sources can accurately reproduce sounds more accurately than CDs by increasing this sampling rate and bit depth numbers (however, whether we can recognize it.)

Apple's wireless headphones, earphones, and speakers all transmit music via Bluetooth, so the audio data must be cut off the data so that the codec can fit into a bit rate that can be transmitted.The codecs used in Bluetooth are all non -possible compression methods, including AAC (Advanced Audio Coding) used by Apple, and sound quality deterioration is inevitable.Sony's LDAC, which claims the sound quality of the "high -resolution class" despite being used in Bluetooth, is also a non -possible compression system.Not a lossless playback.

Then, "Lightning -3" is "Lightning -3.What if you connect with "5mm audio cable"?In this case, Apple says that Loseless regeneration is not possible.Lightning --3.5mm audio cable 3.The analog audio in the 5mm terminal is digitally converted in the cable and outputs to AirPods Max from the Lightning terminal.This digital data is re -converted to analog inside AirPods Max, sent to the driver, and plays it as audio.By the way, the Lightning terminal is not a design that handles analog audio signals.

Then what about a wireless speaker like HomePod, not headphones or earphones?At the time of writing, Apple explains that HomePod cannot play music in lossless.Nevertheless, if you use WiFi instead of Bluetooth, the problem of transmission speed will be substantially eliminated, so in the future, the update of the WiFi speaker function will support Alac (Apple Lossless Audio Codec), an Apple Loseless system.There is a possibility.However, as Apple says, it seems that high-resolution sound sources cannot be played in full style, only by using high-resolution playback support such as USB-DAC on iOS devices, Macs, and PCs.

Apple has announced that it will start distribution of songs using Dolby ATMOS in June, along with streaming at Losless High Reso.As Apple, it is difficult to recognize the differences even if you listen to them very much, and we want to appeal more strongly on the "spatial audio" method that can understand the difference even if you listen to the streaming in high -resolution.It seems to be there.

Dolby Atmos is compatible with AirPods and Beats brand headphones equipped with H1 or W1 chips, and of course HomePod, and Apple TV, such as the latest iPhone, iPad, Mac, and Apple TV.Lothless reproduces the recorded sound as it is, while spatial audio reproduces the "realism" as if it were there, so that the sound could be heard, depths, and nuances more intuitively.It is a technology to do.For us, it should probably be more surprising when listening to ATMOS's spatial audio realism than listening to the sound of lossless and high -restrooming.

There are still few songs that support Dolby Atmos, and at the beginning of the offer, it will be about 200 songs.Nevertheless, Apple says he will provide artists, producers and engineers in this spatial audio format in cooperation with Dolvy La Boratries.It is an idea.
