Review from bluray.com(http://www.blu-ray.com/movies/Avengers-Age-of-Ultron-Blu-ray/55760/#Review)
"Avengers: Age of Ultron Blu-ray, Audio Quality
Avengers: Age of Ultron features a somewhat tepid sounding DTS-HD Master Audio 7.1 mix that provides impeccable surround activity, but is surprisingly (to me, anyway) light from the midrange down to subwoofer territory. Amplitude across the board seems weirdly mitigated as well, with some effects failing to land with the requisite force. Whether this is an intentional approach or the result of someone not paying attention somewhere in the production chain is unclear, but some may find themselves turning their home theater systems "up to 11" to gain a full appreciation of the film's often dense sound mix. Those anomalies aside, the overall mix is quite enveloping from virtually the first moment, when the sounds of battle resound through the side and rear channels very effectively. Later effects, including some neat ping ponging and panning effects during Ultron's "awakening", and the rumbling climax, offer more opportunities for nice aural immersion, albeit with the same somewhat restrained feeling. Dialogue is rendered cleanly and clearly and is always well prioritized."

這位台灣師兄你好
戲院Dolby同家用Dolby在AC3年代以後
兩種Dolby聲軌其實一點關系都沒有
今天發現又有香港朋友在抱怨這張BD的音效不佳，才想到一直忘記回覆你的看法。從Dolby Atmos開始的音效已經與之前的Dolby Digital或DTS完全不同，後者或許都是由PCM轉製，但基本上都是channel-based的音效，Atmos已經是objec-based的音效系統，這也就是為何DTS公司無法將Atmos轉製為DTS HD的原因，兩者是完全不同的音效系統，DTS公司的發言人也已經在去年初的CES承認DTS:X與Atmos不相容。所以，目前Hollywood的大製作電影普遍採用Atmos來後製音效，除非電影公司發行BD時也採用Atmos，否則就算是DTS HD 7.1，仍然會再度發生音效不佳、至少會比電影院播放Atmos版本要差的情形。immersive sound已經是未來4K BD的音效規格，而immersive sound就是objec-based，包括Dolby Atmos、AuroMax以及DTS:X都是objec-based。AuroMax是Auro 3D的upgrade版本，Auro 3D仍然是channel-based，但是AuroMax則是objec-based，Barco已經在今年4月中旬的Cinema Con期間正式宣佈，你可以參考文末的網路連結。
