Definition |
An instance of this DRM class is a single case of the existence of a <DRM Sound> instance within a given transmittal, including variations or specializations unique to that case. A <DRM Sound Instance> instance can represent environmental audio, region-based audio, or spatialized audio:
The active_sound_value specifies the default / active state of the given <DRM Sound> instance, where TRUE indicates on and FALSE indicates off. For a <DRM Sound Instance> instance with a <DRM Sound Instance Control Link> component X, the value of the active_sound_value field is obtained from X. |

Clarifications |
1The <DRM Sound> instance represents the sound recording being instanced. 2The <DRM Fade Range> component specifies the starting distance, relative to the sound source, at which a fade to off should begin and an ending distance, relative to the sound source, at which the fade to off should be complete. The location of the sound source for the <DRM Fade Range> component is determined by:
NOTE If no <DRM Fade Range> component is present, no attenuation is to be performed, which implies instantaneous on / off transitions at the borders of the <DRM Perimeter Data> component and <DRM Sound Volume> component. 3The <DRM Location 3D> component specifies the location of the sound source for spatialized audio. 4The <DRM Perimeter Data> component defines an area within which the <DRM Sound> instance is to be active. 5If a <DRM Sound Instance> instance is subject to dynamic control (that is, if it can be turned on and off), it has a <DRM Sound Instance Control Link> component to express that control mechanism. 6The <DRM Sound Volume> component defines a volume within which the <DRM Sound> instance is to be active. |
