自入手PS4以來,一直都是用光纖 PCM格式輸出聲音
前幾天入手了Harman Kardon Sabre SB35
有支援 ◆ Dolby® Digital TrueHD Decoding
◆ DTS HD Decoding
看了網路上幾篇文章 對於聲音格式的知識仍然很混亂
一篇巴哈的文章 PS3聲音輸出不專業解說:位元流和LPCM的抉擇
裡面提到
選位元流,就是無論聲音訊號格式為何,PS3皆不干涉,直接丟給擴大機去解碼。
選LPCM,就是無論聲音訊號格式為何,PS3通通解碼成PCM格式,擴大機只負責推喇叭不解
碼。
選位元流,你可以聽到比較清晰、品質比較好的聲音,但是沒辦法聽到完整的次世代音效
(會降轉)
選LPCM,你可以享受完整的次世代音效,但是得忍受比較模糊、品質較差的聲音。
這邊的問題是 位元流輸出既然不經過主機直接到擴大機 那為什麼還會被降轉呢?
若擴大機本身可以解次世代音效,是否選擇位元流輸出即可得到最高音質?
