Unity組件：Audio Manager 音頻管理器

The Audio Manager allows you to tweak the maximum volume of all sounds playing in the scene. To see it choose Edit->Project Settings->Audio.

你可以通過(guò)音頻管理器調(diào)整場(chǎng)景中聲音的最大音量。在菜單Edit->Project Settings->Audio打開(kāi)音頻管理器。

Properties 屬性

• Volume 音量
  The volume of all sounds playing. 所有聲音的播放音量
• Rolloff Scale 衰減因子
  Sets the global attenuation rolloff factor for Logarithmic rolloff based sources (see Audio Source). The higher the value the faster the volume will attenuate, conversely the lower the value, the slower it attenuate (value of 1 will simulate the "real world").
  設(shè)置指數(shù)衰減音頻源（參見(jiàn)音頻源）的全局衰減系數(shù)。該數(shù)值越高，音量的衰減速度越快，反之則越慢。（數(shù)值為1則模擬真實(shí)世界的效果）
• Speed of Sound 音速
  The speed of sound. 343 is the real world speed of sound, if you are using a meters as your units. You can adjust this value to make your objects have more or less Doppler effect with larger or smaller speed.
  聲音的傳播速度。如果用米來(lái)做長(zhǎng)度單位的話，現(xiàn)實(shí)世界的音速是每秒343。你可以通過(guò)調(diào)整該數(shù)值來(lái)改變多普勒效應(yīng)的效果。
• Doppler Factor 多普勒因子
  How audible the Doppler effect is. When it is zero it is turned off. 1 means it should be quite audible for fast moving objects.
  模擬多普勒效應(yīng)聽(tīng)起來(lái)的效果。0表示關(guān)閉模擬。1意味著在高速物體上多普勒效應(yīng)會(huì)比較明顯地能聽(tīng)到。
• Default Speaker Mode
  默認(rèn)揚(yáng)聲器模式
  Defines which speaker mode should be the default for your project. Default is 2 for stereo speaker setups (see AudioSpeakerMode in the scripting API reference for a list of modes).
  設(shè)置unity項(xiàng)目中的默認(rèn)揚(yáng)聲器模式。默認(rèn)值為2，即立體聲模式。（模式列表參見(jiàn)腳本API手冊(cè)的AudioSpeakerMode）
• DSP Buffer Size
  DSP緩沖區(qū)大小
  The size of the DSP buffer can be set to optimise for latency or performance
  調(diào)整DSP的緩沖區(qū)的大小可以優(yōu)化延遲和性能。
•     Default 默認(rèn)
  Default buffer size 緩存區(qū)的默認(rèn)大小
•     Best Latency 最小延遲
  Trades off performance in favour of latency 犧牲性能以換取低延遲
•     Good Latency 良好延遲
  Balance between latency and performance 延遲與性能的平衡
•     Best Performance 最佳性能
  Trades off latency in favour of performance 犧牲延遲來(lái)獲取最佳性能

Details 細(xì)節(jié)

If you want to use Doppler Effect set Doppler Factor to 1. Then tweak both Speed of Sound and Doppler Factor until you are satisfied.
Speaker mode can be changed runtime from your application through scripting. See Audio Settings.

如果你想在場(chǎng)景模擬多普勒效應(yīng)，可以把多普勒因子設(shè)為1，然后調(diào)整音速和多普勒因子直到得到滿意的效果。揚(yáng)聲器模式可以在程序運(yùn)行時(shí)通過(guò)腳本實(shí)時(shí)改變。參見(jiàn)Audio Settings音頻設(shè)置。
