Android O 讓手機音質更好了！Google 這次要感謝 Sony？
隨著 Google 正式釋出了 Android O 技術預覽版，外界也得以一窺 Android O 將會帶來
的各項升級。其中無線音樂的音質表現可望有感提升，最大的原因就是 Sony 提供的
LDAC 技術支援！
根據《Android Authority》的報導，Google 在 Android O 系統中採用了更好的藍牙音
樂技術，也就是 LDAC 技術。該技術由 Sony 所開發，可以透過藍牙傳送高達 990kbps
的速度，藉此提升即時音樂無線傳輸數據量。

比起一般的藍牙傳輸 328kbps 的傳輸速度，LDAC 同時間可以傳輸的資料量多了 3 倍以
上，除了能維持最大位元深度，藉由 96 kHz、24 位元的頻率範圍，能確保無線音樂的可
以提供更接近原聲的音質。
先前 LDAC 技術只能在特定 Xperia 機種與 Walkman 裝置上看見，這次在 Android O 的
設計中，Google 讓 LDAC 技術與 aptX 和d aptX-HD 成為藍牙傳輸方式的選項之一，藉
此讓 Android O 裝置可以獲得更好的無線音樂體驗。
LDAC這技術是SONY從Z3+開始導入的，後續期間機種都有這機能，可以將藍芽傳輸
流量提高到990kbps，使得無線藍芽音質可以提升，現在Google直接跟SONY拿授權？
這樣一來之後有更新到Android O的手機都可以有LDAC用，但是配件也是要支援到LDAC
，對於安著手機廠等於說手機可以不用跟SONY買授權，只是藍芽耳機要買LDAC技術授權？
因為LDAC要手機跟耳機都支援才能，就得看其它廠商是否願意買現成的LDAC技術啦
