Audio Plugin Wrapper Extension

Overview

The carb.audio extension wraps up the carb.audio-forge plugin and its associated Python bindings. The plugin does have a C++ interface as well, but it is not exposed here through C++ header files. Only the audio playback interface is exposed through the Python API. The audio capture and audio data management interfaces are not fully exposed to Python here. To use them, the C++ API should be used directly instead.

This extension has two main purposes:

  • To expose the Python API for the plugin to Kit based apps. Other extensions or app developers can simply import the carb.audio Python module and make use of its interfaces for audio playback.

  • To act as a dependency for other extensions that want to use the C++ API and plugin. If this extension is loaded as a dependency of another extension or an app, all of its interfaces become available through the normal interface framework.

Note that the Python API for this extension will operate on separate audio contexts from the one that is associated with the current USD stage. In the current version it is not possible to retrieve the audio playback context used by the current USD stage. Similarly, this Python API cannot be used to interoperate with the objects returned from the USD stage audio API.
