# MPEG-H 3D Audio Renderer

#### Applicability

This description applies to the MPEG-H 3D Audio Renderer module.

#### Overview

MPEG-H 3D Audio Renderer is a module for rendering MPEG-H 3D Audio content according to its metadata and user input to a selected monitoring or output target.

#### Processing Principle

The module uses the selected metadata source to render the incoming audio signals. Users can select the presentation, user data and output format either for quality checking the signal or creating channel based downmixes for further processing or distribution.
