A new audio object will implement the following functions depending on functionality. See the header files for the associated classes for detailed comments.

In the class which inherits CAudioObject – ie: CYourAudioObject.cpp

Abstract Methods (required implementation)

xUInt32 CAudioObject::getSize() const 

Virtual Methods (optional implementation – depending on object features). This is not a complete list but contains the major virtual methods.

void      CAudioObject::init()
void      CAudioObject::calc(xFloat32** inputs, xFloat32** outputs)
void      CAudioObject::tuneXTP(xSInt32 subblock, xSInt32 startMemBytes, xSInt32 sizeBytes, xBool shouldAttemptRamp)
void      CAudioObject::controlSet(xSInt32 index, xFloat32 value)
xAF_Error CAudioObject::controlSet(xSInt32 index, xUInt32 sizeBytes, const void * const pValues)
void      CAudioObject::assignAdditionalConfig()
xInt8*    CAudioObject::getSubBlockPtr(xUInt16 subBlock)
xSInt32   CAudioObject::getSubBlockSize(xUInt16 subBlock)

In the class which inherits CAudioObjectToolbox – ie: CYourAudioObjectToolbox.cpp

const CAudioObjectToolbox::tObjectDescription*          CAudioObjectToolbox::getObjectDescription()
const CAudioObjectToolbox::tModeDescription*            CAudioObjectToolbox::getModeDescription(xUInt32 mode)
const CAudioObjectToolbox::additionalSfdVarDescription* CAudioObjectToolbox::getAdditionalSfdVarsDescription(xUInt32 index)
xAF_Error                                               CAudioObjectToolbox::getObjectIo(ioObjectConfigOutput* configOut)
xUInt32                                                 CAudioObjectToolbox::getXmlSVTemplate(tTuningInfo* info, xInt8* buffer, xUInt32 maxLen)
xUInt32                                                 CAudioObjectToolbox::getXmlObjectTemplate(tTuningInfo* info, xInt8* buffer, xUInt32 maxLen)
xUInt32                                                 CAudioObjectToolbox::getXmlFileInfo(tTuningInfo* info, xInt8* buffer, xUInt32 maxLen)
void                                                    CAudioObjectToolbox::createStaticMetadata()
void                                                    CAudioObjectToolbox::createDynamicMetadata(ioObjectConfigInput& configIn, ioObjectConfigOutput& configOut)

In the class which inherits CMemoryRecordProperties – ie: CYourAudioObjectMemRecs.cpp

xUInt8 CMemoryRecordProperties::getMemRecords(xAF_memRec* memTable, xAF_memRec& scratchRecord, xInt8 target, xInt8 format)
