Detailed Description

Defines a room for the spatial audio engine.

If the listener is inside a room, first order sound reflections and reverb matching the rooms properties will get applied to the sound field.

A room is always square and defined by its center position, its orientation and dimensions. Each of the 6 walls of the room can be made of different materials that will contribute to the computed reflections and reverb that the listener will experience while being inside the room.

If multiple rooms cover the same position, the engine will use the room with the smallest volume.

class Material

Defines different materials that can be applied to the different walls of the room.

Constant	Description
QAudioRoom.Transparent	The side of the room is open and won’t contribute to reflections or reverb.
QAudioRoom.AcousticCeilingTiles	Acoustic tiles that suppress most reflections and reverb.
QAudioRoom.BrickBare	Bare brick wall.
QAudioRoom.BrickPainted	Painted brick wall.
QAudioRoom.ConcreteBlockCoarse	Raw concrete wall
QAudioRoom.ConcreteBlockPainted	Painted concrete wall
QAudioRoom.CurtainHeavy	Heavy curtain. Will mostly reflect low frequencies
QAudioRoom.FiberGlassInsulation	Fiber glass insulation. Only reflects very low frequencies
QAudioRoom.GlassThin	Thin glass wall
QAudioRoom.GlassThick	Thick glass wall
QAudioRoom.Grass	Grass
QAudioRoom.LinoleumOnConcrete	Linoleum floor
QAudioRoom.Marble	Marble floor
QAudioRoom.Metal	Metal
QAudioRoom.ParquetOnConcrete	Parquet wooden floor on concrete
QAudioRoom.PlasterRough	Rough plaster
QAudioRoom.PlasterSmooth	Smooth plaster
QAudioRoom.PlywoodPanel	Plywodden panel
QAudioRoom.PolishedConcreteOrTile	Polished concrete or tiles
QAudioRoom.Sheetrock	Rock
QAudioRoom.WaterOrIceSurface	Water or ice
QAudioRoom.WoodCeiling	Wooden ceiling
QAudioRoom.WoodPanel	Wooden panel
QAudioRoom.UniformMaterial	Artificial material giving uniform reflections on all frequencies

class Wall

An enum defining the 6 walls of the room

Constant	Description
QAudioRoom.LeftWall	Left wall (negative x)
QAudioRoom.RightWall	Right wall (positive x)
QAudioRoom.Floor	Bottom wall (negative y)
QAudioRoom.Ceiling	Top wall (positive y)
QAudioRoom.FrontWall	Front wall (negative z)
QAudioRoom.BackWall	Back wall (positive z)

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property dimensionsᅟ: QVector3D

Defines the dimensions of the room in 3D space. Units are in centimeters by default.

See also

position distanceScale

Access functions:

• dimensions()

• setDimensions()

• Signal dimensionsChanged()

property positionᅟ: QVector3D

Defines the position of the center of the room in 3D space. Units are in centimeters by default.

See also

dimensions distanceScale

Access functions:

• position()

• setPosition()

• Signal positionChanged()

property reflectionGainᅟ: float

A gain factor for reflections generated in this room. A value from 0 to 1 will dampen reflections, while a value larger than 1 will apply a gain to reflections, making them louder.

The default is 1, a factor of 0 disables reflections. Negative values are mapped to 0.

Access functions:

• reflectionGain()

• setReflectionGain()

• Signal reflectionGainChanged()

property reverbBrightnessᅟ: float

A brightness factor to be applied to the generated reverb. A positive value will increase reverb for higher frequencies and dampen lower frequencies, a negative value does the reverse.

The default is 0.

Access functions:

• reverbBrightness()

• setReverbBrightness()

• Signal reverbBrightnessChanged()

property reverbGainᅟ: float

A gain factor for reverb generated in this room. A value from 0 to 1 will dampen reverb, while a value larger than 1 will apply a gain to the reverb, making it louder.

The default is 1, a factor of 0 disables reverb. Negative values are mapped to 0.

Access functions:

• reverbGain()

• setReverbGain()

• Signal reverbGainChanged()

property reverbTimeᅟ: float

A factor to be applies to all reverb timings generated for this room. Larger values will lead to longer reverb timings, making the room sound larger.

The default is 1. Negative values are mapped to 0.

Access functions:

• reverbTime()

• setReverbTime()

• Signal reverbTimeChanged()

property rotationᅟ: QQuaternion

Defines the orientation of the room in 3D space.

Access functions:

• rotation()

• setRotation()

• Signal rotationChanged()
