VR系列——Oculus Audio sdk文档：八、Oculus Spatializer AAX集成指南（1~2）——概述及使用插件

概述（Overview）

  Oculus Spatializer AAX插件是一个Avid 的Pro Tools音频制作平台的附加插件。
  The Oculus Spatializer AAX plugin is an add-on plugin for Avid’s Pro Tools audio production platform.

  这个插件可以实现基于用户头部位置的单声道声源的3D效果。
  This plugin allows for monophonic sound sources to be properly spatialized in 3D relative to the user’s head location.

  AAX插件融合了在其他插件格式中使用的相同的空间算法（如：Wwise，Unity）。这些其他格式通常用于生成虚拟环境内的实时空间。对于音频设计师来说，AAX插件是用于在Pro Tools DAW（数字音频工作站）中设置混音，要知道在虚拟现实中，混音的优先级高于音频空间化。
  The AAX plugin incorporates the same spatialization algorithms found in our other plugin formats (e.g., Wwise, Unity). These other formats are typically used to generate real-time spatialization within virtual environments. For the audio designer, the AAX plugin is useful for setting up mixes within the Pro Tools DAW (Digital Audio Workstation) and for hearing what the mix will sound like prior to being spatialized in virtual reality.

版本兼容性（Version Compatibility）

  AAX插件已经在Windows 7 和 8, 以及 OS X 10.10+的Pro Tools 11 (64-bit) 下测试过。
  The AAX plugin has been tested in Pro Tools 11 (64-bit) on Windows 7 and 8, and OS X 10.10+.

OSP的一般限制（General OSP Limitations）

1. 当早期反射被开启时CPU使用率会增加，且CPU使用率会随着空间面积的扩大而提高。（CPU usage increases when early reflections are turned on, and increases proportionately as room dimensions become larger.）

AAX的具体限制（Limitations Specific to AAX）

1. 所有参数被分配到MIDI控制器。然而，大多数参数范围落在当前MIDI映射范围0.0 - 1.0之外。每个参数的范围设置将在之后的插件版本中得到解决。（All parameters are assigned to MIDI controllers. However, most parameter ranges fall outside of the current MIDI mapping range of 0.0 - 1.0. Range settings for each parameter will be resolved in a future release of the plugin.）
2. 为了保证的最佳保真度必须将Pro Tools的采样率设置为44.1kHz或48kHz。需要注意的是当值低于16 kHz或高于48kHz时会没有声音。（You must set the Pro Tools sample rate to be at 44.1 kHz or 48 kHz for optimal fidelity. Note that values below 16 kHz or above 48 kHz will result in no sound.）

安装（Installation）

复制Oculus Spatializer.aaxplugin到Avid Pro Tools Plug-Ins目录。
Copy Oculus Spatializer.aaxplugin to the Avid Pro Tools Plug-Ins folder

Mac：

Macintosh HD/Library/Application Support/Avid/Audio/Plug-Ins

PC：

C:\Program Files\Common Files\Avid\Audio\Plug-Ins

使用插件（Using the Plugin）

  我们建议将Oculus Spatializer作为Pro Tools的单声道音轨的插入效果。这样在这个音轨播放的声音将通过空间化进程影响全局。
  We recommend assigning the Oculus Spatializer as an insert effect to a mono track in Pro Tools. Any sound that plays through this track will then be globally affected by the spatialization process.
