Detailed Description

\inmodule QtSpatialAudio

A sound object in 3D space.

QSpatialSound represents an audible object in 3D space. You can define its position and orientation in space, set the sound it is playing and define a volume for the object.

The object can have different attenuation behavior, emit sound mainly in one direction or spherically, and behave as if occluded by some other object.

Member Enumeration Documentation

◆ DistanceModel

enum class QSpatialSound::DistanceModel

strong

Defines how the volume of the sound scales with distance to the listener.

\value Logarithmic Volume decreases logarithmically with distance. \value Linear Volume decreases linearly with distance. \value ManualAttenuation Attenuation is defined manually using the \l manualAttenuation property.

Property Documentation

◆ autoPlay

QSpatialSound::autoPlay

readwrite

Determines whether the sound should automatically start playing when a source gets specified.

The default value is true.

Definition at line 33 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::autoPlay(), and setAutoPlay().

◆ directivity

QSpatialSound::directivity

readwrite

Defines the directivity of the sound source.

A value of 0 implies that the sound is emitted equally in all directions, while a value of 1 implies that the source mainly emits sound in the forward direction.

Valid values are between 0 and 1, the default is 0.

Definition at line 29 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::directivity().

◆ directivityOrder

QSpatialSound::directivityOrder

readwrite

Defines the order of the directivity of the sound source.

A higher order implies a sharper localization of the sound cone.

The minimum value and default for this property is 1.

Definition at line 30 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::directivityOrder().

◆ distanceCutoff

QSpatialSound::distanceCutoff

readwrite

Defines a distance beyond which sound coming from the source will cutoff.

If the listener is further away from the sound object than the cutoff distance it won't be audible anymore.

Definition at line 26 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::distanceCutoff().

◆ distanceModel

QSpatialSound::distanceModel

readwrite

Defines distance model for this sound source.

The volume starts scaling down from \l size to \l distanceCutoff. The volume is constant for distances smaller than size and zero for distances larger than the cutoff distance.

See also: QSpatialSound::DistanceModel

Definition at line 24 of file qspatialsound.h.

◆ loops

QSpatialSound::loops

readwrite

Determines how many times the sound is played before the player stops.

Set to QSpatialSound::Infinite to play the current sound in a loop forever.

The default value is 1.

Definition at line 32 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::loops(), and setLoops().

◆ manualAttenuation

QSpatialSound::manualAttenuation

Defines a manual attenuation factor if \l distanceModel is set to QSpatialSound::DistanceModel::ManualAttenuation.

Definition at line 27 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::manualAttenuation().

◆ nearFieldGain

QSpatialSound::nearFieldGain

readwrite

Defines the near field gain for the sound source.

Valid values are between 0 and 1. A near field gain of 1 will raise the volume of the sound signal by approx 20 dB for distances very close to the listener.

Definition at line 31 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::nearFieldGain().

◆ occlusionIntensity

QSpatialSound::occlusionIntensity

readwrite

Defines how much the object is occluded.

0 implies the object is not occluded at all, 1 implies the sound source is fully occluded by another object.

A fully occluded object will still be audible, but especially higher frequencies will be dampened. In addition, the object will still participate in generating reverb and reflections in the room.

Values larger than 1 are possible to further dampen the direct sound coming from the source.

The default is 0.

◆ position

QSpatialSound::position

readwrite

Defines the position of the sound source in 3D space.

Units are in centimeters by default.

See also: QAudioEngine::distanceScale

Definition at line 21 of file qspatialsound.h.

◆ rotation

QSpatialSound::rotation

readwrite

Defines the orientation of the sound source in 3D space.

Definition at line 22 of file qspatialsound.h.

◆ size

QSpatialSound::size

readwrite

Defines the size of the sound source.

If the listener is closer to the sound object than the size, volume will stay constant. The size is also used to for occlusion calculations, where large sources can be partially occluded by a wall.

◆ source

QSpatialSound::source

readwrite

The source file for the sound to be played.

Definition at line 20 of file qspatialsound.h.

Referenced by QQuick3DSpatialSound::source().

◆ volume

QSpatialSound::volume

readwrite

Defines the volume of the sound.

Values between 0 and 1 will attenuate the sound, while values above 1 provide an additional gain boost.
