正視聽 Apple 講到明如要用無損音樂，一定要插DAC先用到

Due to the large file sizes and bandwidth needed for Lossless and Hi-Res Lossless Audio, subscribers will need to opt in to the experience. Hi-Res Lossless also requires external equipment, such as a USB digital-to-analog converter (DAC).

反而杜比Atmos 唔使

Apple is bringing Spatial Audio with support for Dolby Atmos to Apple Music. Dolby Atmos is a revolutionary, immersive audio experience that enables artists to mix music so the sound comes from all around and from above. By default, Apple Music will automatically play Dolby Atmos tracks on all AirPods and Beats headphones with an H1 or W1 chip, as well as the built-in speakers in the latest versions of iPhone, iPad, and Mac.

Apple 行 AAC, 比你機內放 24/196 AIFF 都係壓做 256kbps AAC 先傳去隻 AirPods 度

Dolby Atmos 只要喺 bandwidth 限制下都傳到落 AirPods 就得，話唔定係壓到 ~200 然後果 56kpbs quota 來傳 Atmos code

Fpt 爆apple為左唔俾人告anti先咁做 ，之後會用類似AirPlay 技術 播

Hi-Res Lossless 呀
普通CD lossless iPod classic都播到啦

問題係依家iphone cut左3.5真係CD都做唔到

唔知macbook 插3.5 播唔播到

放心啦， 呢間吸血鬼公司一定迫你買新/ 加舊嘢先玩到

咁如果係android dap用Apple Music播又食唔食到

重諗住賣鬼咗部dac 佢 留多一排試下
