Magnum::Audio namespace

Audio playback.

Contents

Audio import, playback and integration with SceneGraph.

This library depends on the OpenAL library. It is built if WITH_AUDIO is enabled when building Magnum. To use this library with CMake, you need to request the Audio component of the Magnum package and link to the Magnum::Audio target:

find_package(Magnum REQUIRED Audio)

# ...
target_link_libraries(your-app Magnum::Audio)

Additional plugins and utilities are built separately. See particular Audio::*Importer class documentation, the magnum-al-info utility documentation, Downloading and building, Downloading and building plugins, Usage with CMake, Plugin usage with CMake and Loading and using plugins for more information.
