● Qt6 audio Returns the engine associated with this listener. Function Documentation float QtAudio:: convertVolume (float volume, QtAudio::VolumeScale from, QtAudio::VolumeScale to). Shows some of the capabilities of the spatial audio engine in Qt. QSpatialSound. The examples listed below show some typical use cases where audio sources are located in 3D space adding virtual rooms around the source. Sets or returns overall volume being used to render the sound field. QAudioEngine *QAudioListener:: engine const. A sound field is defined by several QSpatialSound objects that define a sound at a specified location in 3D space. The default constructed QAudioInput selects the system default audio input. UI volume controls should usually be scaled non-linearly. Classes. The recorder controls the recording process with a simple record() and stop() An audio format specifies how data in a raw audio stream is arranged. To select a certain audio device for input or output set it as the device on AudioInput or AudioOutput. Qt provides the QAudioSource class to enable audio functionality within a standard application user interface. QAudioFormat contains parameters that specify how the audio sample data is arranged. [virtual noexcept] QAudioListener:: ~QAudioListener Destroys the listener. The MediaPlayer component is a non-visual item that connects a media source to one or several output channel(s). This code snippet is in Qt5 documentation, not in Qt6. As the rest of Qt Quick 3D, the audio engine uses a coordinate system that is in centimeters by default.
