.atmosIR 文件是什么，有什么用途？

.atmosIR文件是一种杜比全景声渲染器的配置文件，可以导入与导出，它包括：

  • 输入配置
    • 用于Bed的输入通道
    • Bed的宽度
    • 用于Object的输入通道
    • 编组和命名信息
    • Bed和Object的组分配
    • 输入通道的描述信息
  • Re-render的定义
    • 名称
    • 宽度
    • 属性
      • 全部混音
      • 仅Bed
      • 仅Object
      • 自定义 - 使用组定义和分配
  • 双耳渲染器（binaural renderer）模式设置
    • 除了输入设置以外，还包括
    • 每个输入的开关和距离设置（Object或每个Bed通道 - 关闭、近、中、远）

.atmosIR文件通过以下渲染器的功能使用

  • File // Import Input/Binaural/Re-Render Config
  • File // Export Input/Binaural/Re-Render Config

当导入一个.atmosIR文件时，用户可以选择“apply the file to Input Only（仅导入输入配置）”、“ Input and Binaural Render Mode（导入输入配置和双耳渲染模式）”、“Re-Renders.（导入再渲染的配置）”。

在v3.x版本渲染器之前，.atmosIR的前身是.rmuio。他包含输入和Re-render配置信息，不过没有双耳渲染模式设置。老的.rmuio文件在v3.0中依然能导入。

.atmosIR中的信息也保存在母版的.atmos文件中。不过独立的.atmosIR文件可以在建立新的母版文件时确保渲染器输入配置和Pro Tools的输出配置是匹配的。Pro Tools的输出配置保存在Pro Tools工程文件中或者单独保存为.pio文件。在渲染器中从头开始配置一个非默认设置会消耗大量人力劳动，.atmosIR文件可以极大的提高效率，尤其是在重复使用相同配置的情况。比如，在一部剧集中每一集都使用了相同的自定义Pro Tools模板。将ADM文件以工程数据的方式导入Pro Tools ，加载相应的.atmosIR到渲染器中，就可以开始工作了。

.atmoscfg文件是独立的配置文件。包括渲染器房间配置、输出分配、增益、均衡和自定义扬声器布局等等。

What are .atmosIR files and what can they be used for?

An .atmosIR file is a type of config file used by our Atmos Renderer that can be exported/imported. It contains:

  • input configuration:
    • inputs dedicated to bed(s)
    • width of bed(s)
    • inputs dedicated to objects
    • group creation and naming
    • bed and object assignment to groups
    • input descriptions
  • re-render definitions:
    • name
    • width
    • properties
      • fullmix
      • beds only
      • objects only
      • custom – using the group definitions and assignments
  • binaural renderer mode settings:
    • populated from the input configuration but also includes:
    • on/off and distance settings per input (objects or individual bed channels– off, near, mid, far).

.atmosIR files are used with Renderer functions:

  • File/Import Input/Binaural/Re-Render Config
  • File/Export Input/Binaural/Re-Render Config

When importing a .atmosIR file the user can choose to apply the file to Input Only, Input and Binaural Render Mode and/or to the Re-Renders.

The predecessor to the Atmos.IR file used prior to Renderer v3.x was the .rmuio file type. These contained the input and re-render info but not the binaural renderer mode settings. Older
.rmuio files can still be imported into v3.x.

All the information in the .atmosIR file is also saved in the master .atmos file. But the separate .atmosIR file is useful for setting up the renderer to work with a new master and making sure the Input Configuration matches the output configuration of Pro Tools (which is saved with the Pro Tools session or separately as .pio file). Setting the Renderer up from scratch with non-default settings can be labor intensive so .atmosIR files can speed things up considerably especially if the same configurations are used repeatedly i.e. with the same custom Pro Tools template for every episode in a series etc. Importing a ADM.wav into Pro Tools as session data and loading a corrsponding .atmos.IR to the Renderer means you can start working right away.

The .atmosIR is a separate config file from the .atmoscfg which contains Renderer room setup info, output assignments, gain, eq, custom monitor layouts etc
