ttv::OperatorChainBuilder

struct ttv::OperatorChainBuilder

template<typename ContextType, typename InputBufferFormat, typename OutputBufferFormat, size_t SelectedChannelIndex>
struct ttv::OperatorChainBuilder< ContextType, InputBufferFormat, OutputBufferFormat, SelectedChannelIndex >

This class builds a chain of operators to convert audio from a given input buffer format to an output buffer format.

Template Parameters

ContextType	The type of AudioConvertContext for the operators to use. See audioconvertcontext.h
InputBufferFormat	The input buffer format. See BufferFormat in dsputilities.h
OutputBufferFormat	The output buffer format. See BufferFormat in dsputilities.h
SelectedChannelIndex	Which input audio channel this chain will process.

ttv::OperatorChainBuilder::MakeSignedIfIntegralSelector

struct ttv::OperatorChainBuilder::MakeSignedIfIntegralSelector

template<typename ContextType, typename InputBufferFormat, typename OutputBufferFormat, size_t SelectedChannelIndex>
template<typename ScalarType, typename Enable = void>
struct ttv::OperatorChainBuilder< ContextType, InputBufferFormat, OutputBufferFormat, SelectedChannelIndex >::MakeSignedIfIntegralSelector< ScalarType, Enable >

std::make_signed chokes if we pass it a non-integral type. We sometimes want to pass floating-point types in the algorithm below, so this is a more lenient version that is just a no-op for floating-point types.
