Typedef Documentation

DynamicDataTypeNone

using JPL::VBAP::DynamicDataTypeNone = typedef void*

GainPack

template<class T >

using JPL::VBAP::GainPack = typedef std::array<T, 3>

Alias for speaker triplet gains.

GainTypeNone

using JPL::VBAP::GainTypeNone = typedef void*

LUT can be made out of just the selected speaker triplets, without precomputed gains.

LUT_65

template<size_t N, CVec3 Vec3Type>

using JPL::VBAP::LUT_65 = typedef LUTBase<N, GainTypeNone, TripletIdx, DynamicDataWithMat<Vec3Type> >

LUT_655

template<size_t N>

using JPL::VBAP::LUT_655 = typedef LUTBase<N, Gain24Bit, TripletIdx, DynamicDataTri>

LUT_786

template<size_t N>

using JPL::VBAP::LUT_786 = typedef LUTBase<N, Gain24Bit, SpeakerTripletIdx>

LUT_851

template<size_t N>

using JPL::VBAP::LUT_851 = typedef LUTBase<N, float, TripletIdx, DynamicDataTri>

LUT_983

template<size_t N>

using JPL::VBAP::LUT_983 = typedef LUTBase<N, float, SpeakerTripletIdx>

Just some more convenient aliases.

SpeakerIdx

using JPL::VBAP::SpeakerIdx = typedef uint8

Index of a speaker/channel.

SpeakerTripletIdx

using JPL::VBAP::SpeakerTripletIdx = typedef std::array<SpeakerIdx, 3>

Direct indices of the speakers, corersponding to channels in the output buffer.

TripletIdx

using JPL::VBAP::TripletIdx = typedef uint8

Index of a 'SpeakerTripletIdx' (one extra indirection to select actual speakers/channels) For this, a small array of all triplets has to be stored alongside the LUT

Enumeration Type Documentation

ELUTSize

enum class JPL::VBAP::ELUTSize

strong

LUT type selector parameter based on approximate size of the static data. Sizes are approximate for Octahedron16Bit encoding, not including dynamic data.
