杜比全景声渲染器v3.x创建的.atmos文件是否和老版本兼容？

是的，只要不增加Bed（声床）的数量，或者将双耳渲染元数据（Binaural Metadata）写入Bed

  • 杜比全景声渲染器v3.x可以创建的文件为damf v0.5（杜比全景声母版格式）

  • 在DAPSv2.5.3中创建的母版文件是damf v0.5，和杜比全景声渲染器v3.0.0是兼容的

  • 杜比全景声家庭影院渲染器（Dolby Atmos Home Theater Renderer）v1.7.2创建的母版文件（damf v0.4）可以打开、播放并编辑。用户在解锁母版文件时会受到警告：如果增加了Bed将无法和v1.7.2版本的渲染器兼容

  • 在杜比全景声家庭影院渲染器（Dolby Atmos Home Theater Renderer）v1.7.2之前的版本中创建的母版文件（damf v0.3）仅能以只读的方式打开

  • 杜比全景声渲染器v3.0中可以在Bed通道中写入双耳渲染元数据（Binaural Metadata），这样会造成母版文件无法兼容DAPS v2.5.3、杜比家庭影院渲染器v1.7.2和DMP v2.3（杜比媒体制作工具）。此功能需要在双耳元数据（Binaural Metadata）窗口中手动开启

Are .atmos created with version the Dolby Atmos Renderer v3.x backwards compatible?

Yes. As long as multiple beds are not added, and as long as binaural metadata is not written to beds.

  • Dolby Atmos Renderer v3.x. creates damf v.0.5 files

  • Files created in Dolby Atmos Production Suite v2.5.3 (damf v0.5) are compatible with the Dolby Atmos Renderer v3.0.0.

  • Files created in Dolby Atmos Home Theater Renderer v1.7.2 (damf v0.4) are openable, playable and editable. The user is warned when unlocking that the file will not be backwards compatible with Dolby Atmos Home Theater Renderer v1.7.2 if multiple beds are added.

  • Files created pre Dolby Atmos Home Theater Renderer v1.7.2 (damf v0.3) are opened as read only

  • The Dolby Atmos Renderer v3.0.0 has the ability to write binaural metadata into bed channels. The resultant file will be incompatible with Dolby Atmos Production Suite v2.5.3, Dolby Atmos Home Theater Renderer v1.7.2, Dolby Media Producer v2.3, This function has to be unlocked by the user in the binaural metadata window
