Detailed Description

\inmodule QtSpatialAudio

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.

Member Enumeration Documentation

Material

enum QAudioRoom::Material

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

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