Hi coma hing

我想問下 atmos 7.1.4中的.4 ch已知如你所提及的由AV Processor的處理器去計算出物件位置再 ...

咁bluray disk 就要有atmos 及non-atmos的2種完全不同的數據?

唔會.....本身TrueHD聲軌上有個code
AVamp認到就會拆訊號去派聲

AAA1

About ceiling or top layer speakers orientation
For Atmos, they are directed downward towards listening position
For DTS X,  the speakers are directed at a higher level at around 2 meters from floor at the listening position
For Auro, the middle layer speakers are also more horizontal firing
Which one should be better?

最實際係片源行7.1就用返7.1
唔好玩UPMIX去DDsurr/A3D
依家atmos片源多就跟atmos喇叭裝法
得唔得可以去atmos戲院入場參考效果
dtsX戲院效果暫時唔知邊度有(upmix唔算)
至於天花裝幾多隻就按自己實際環境量力而為
如果一般家居揀裝10隻唔到位喇叭定係揀4隻到位
我一定揀4隻到位天花喇叭

所以天龍連入門機粒DSP晶片都係行4核
不過都係基本野除咗處理派聲
高端機種仲處理埋所有聲道獨立EQ同相位分頻

完全正確⋯⋯
而且電影聲音原生亦係 7.1 去做後期制作(混音)⋯⋯Dolby Atmos / DTS:X / Auro 3D
以個人認為 ...

無計Dolby都話要跟空間同錢妥協
妥協唔到唯有比錢入戲院睇
