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.
If you are new to Qt Spatial Audio, the QML types can be
imported
into an application using the following statement in your
.qml
文件。
import QtQuick3D.SpatialAudio
To link against the C++ libraries, add the following to your project's
CMakeLists.txt
file. Substitute
my_project
with the name of your project.
find_package(Qt6 REQUIRED COMPONENTS SpatialAudio)
target_link_libraries(my_project PRIVATE Qt6::SpatialAudio)
