Qt Spatial Audio

Qt Spatial Audio is an add-on module that provides a rich set of QML types and C++ classes to implement sound fields in 3D space. It contains an easy to use API for positing a listener in space, adding localized sound sources around the listener and emulating virtual rooms with reverb and reflections.

快速入门

If you are new to Qt Spatial Audio, the QML types can be imported 进应用程序使用以下语句在 .qml 文件。

import QtQuick3D.SpatialAudio
					

要链接到 C++ 库,添加以下到工程 CMakeLists.txt 文件。代入 my_project 采用工程名称。

find_package(Qt6 REQUIRED COMPONENTS SpatialAudio)
target_link_libraries(my_project PRIVATE Qt6::SpatialAudio)
