Types

Provides the public data types (typedefs and enums) used by the RoomAcoustiC++ API.

These types are used when configuring the spatialiser and when updating listener/source state.

  • Namespace: RAC::Spatialiser
  • Header: Spatialiser/Types.h
  • Source: (header only)
  • Dependencies: Common/Coefficients.h, Common/Vec3.h

Typedefs

using Vertices = std::array<Vec3, 3>

Triangle vertices used to define a wall surface.

Enums

enum class SpatialisationMode

Controls how direct sound is spatialised.

  • SpatialisationMode::none: no spatialisation (mono)
  • SpatialisationMode::performance: performance mode (interaural time and level differences)
  • SpatialisationMode::quality: quality mode (HRTF-based)

enum class SourceDirectivity

Selects the directivity pattern used by a source.

  • SourceDirectivity::omni
  • SourceDirectivity::subcardioid
  • SourceDirectivity::cardioid
  • SourceDirectivity::supercardioid
  • SourceDirectivity::hypercardioid
  • SourceDirectivity::bidirectional
  • SourceDirectivity::genelec8020c
  • SourceDirectivity::genelec8020cDTF
  • SourceDirectivity::qscK8

enum class DiffractionModel

Selects the diffraction model.

  • DiffractionModel::attenuate: distance attenuation only (shadow zone)
  • DiffractionModel::lowPass: 1 kHz low-pass filter (shadow zone)
  • DiffractionModel::udfa: UDFA model
  • DiffractionModel::udfai: UDFA-I model (shadow zone)
  • DiffractionModel::nnBest: neural network model (shadow zone)
  • DiffractionModel::nnSmall: smaller neural network model (shadow zone)
  • DiffractionModel::utd: UTD-based model (shadow zone)
  • DiffractionModel::btm: BTM model

enum class ReverbFormula

Selects the formula used to estimate late reverberation time.

  • ReverbFormula::Sabine
  • ReverbFormula::Eyring
  • ReverbFormula::Custom: use user-provided T60 values

enum class FDNMatrix

Selects the feedback matrix used by the feedback delay network.

  • FDNMatrix::householder
  • FDNMatrix::randomOrthogonal

enum class DirectSound

Selects how the direct sound path is handled.

  • DirectSound::none: no direct sound
  • DirectSound::doCheck: perform visibility check
  • DirectSound::alwaysTrue: always consider direct sound present

enum class LateReverbModel

Late reverberation model selection.

In typical usage this is selected automatically based on which late reverberation initialisation function you call.

  • LateReverbModel::none: no late reverberation
  • LateReverbModel::fdn: feedback delay network (SingleFDN)
  • LateReverbModel::raves: MoD-ART late reverberation model

enum class DiffractionSound

Controls whether diffraction sound is rendered.

  • DiffractionSound::none: no diffraction sound
  • DiffractionSound::shadowZone: render diffraction only in the shadow zone (recommended)
  • DiffractionSound::allZones: render diffraction in all zones
