你的喇叭數目如何，你的Dolby Atmos效果也必如何

How is Dolby Atmos different than typical channel-based home theater systems?

Dolby Atmos is the first home theater system that is based not on channels, but on audio objects. What is an audio object? Any sound heard in a movie scene—a child yelling, a helicopter taking off, a car horn blaring—is an audio object. Filmmakers using Dolby Atmos can decide exactly where those sounds should originate and precisely where they move as the scene develops.

Thinking about sound in this way eliminates many of the limitations of channel-based audio. In a channel-based system, filmmakers have to think about the speaker setup: Should this sound come from the left rear surrounds or the left side surrounds? With Dolby Atmos, filmmakers just have to think about the story: Where is that yelling child going to run? The Dolby Atmos system, whether in the cinema or a home theater, has the intelligence to determine what speakers to use to precisely recreate the child’s movement in the way the filmmakers intend.

Dolby Atmos is also far more flexible and adaptable than channel-based home theater. In a channel-based system with channel-based content, the number of speakers is fixed—a 7.1 system always consists of seven speakers and one subwoofer. With Dolby Atmos, in contrast, you have amazing flexibility: you can get the full experience with just seven speakers or get an even richer, more detailed sound by adding more speakers. As you add speakers, a Dolby Atmos enabled receiver will automatically determine how to use them to create fantastic, immersive audio.

If Dolby Atmos allows me to add more speakers, why do I see A/V receivers with just 11 channels?

Many hardware partners are building or planning to build Dolby Atmos enabled A/V receivers and speakers. Those partners decide what product configurations make the most sense for their customers. But the Dolby Atmos system itself is almost unlimited. If you have the space and budget, you can build a Dolby Atmos system with as many as 24 speakers on the floor and 10 overhead speakers. One of our hardware partners is planning to release an A/V receiver with 32 channels.

如果以一般家居講，要將surround放到耳仔水平，可能要考慮一下入牆或扁身嘅掛牆喇叭。當然在音色同音效中可能要作出取捨了。

Pac兄反而可以考慮在sofa兩側用上坐地作surround，玩5.1.2/4 效果應該會好好。

我昨晚坐最後果行,所以效果不是太好,但都聽到surround的效果比傳統好,補充返頭頂的聲音細節.
一般香港家庭要玩Atmos,真系好難,特別系喇叭放耳邊的效果比掛牆好.難取捨.

我都會諗諗加1對走鬼surround喇叭放sofa2邊耳仔高度, 將原先掛假天花既surround換成指向式(盡諗全頻)做atoms, 加多對atoms enabled speaker喺前置, 或者將本身對front height做atoms.......呢個係暫時諗法....等有錢先再決定.....{:9_428:}

相信係唔係全頻問題唔大，Bass Management會幫你攪，戲院啲天花喇叭都唔係全頻。

just my 2 cents

我打算咁擺，耳水平高一尺,第時可以放回耳水平,試左先

尾頂喇叭用返b&W三角喇叭玩下5.1.4先
