Public function Static TSharedPtr< FWaveTableOsc >

CreateWaveTable ( const EWaveTable::Type WaveTableType,
const int32 WaveTableSize
)

 Creates a wave table using internal factories for standard wave tables or uses custom wave table factor if it exists.
Public function void

Generate ( float* OutputNormalPhase,
float* OutputQuadPhase
)

 Processes the wave table, outputs the normal and quad phase (optional) values.
Public function Const float Returns the frequency of the wave table oscillator.
Public function TArray< float > & Returns the internal table used in the wave table.
Public function Const const TArray< float > & Returns the internal table used in the wave table.
Public function Const EWaveTable::Type

GetType ()

 Returns the type of the wave table oscillator.
Public function void

Init ( const float InSampleRate,
const float InFrequencyHz
)

 Initialize the wave table oscillator.
Public function void

Reset ()

 Resets the wave table read indices.
Public function void

SetFrequencyHz ( const float InFrequencyHz
)

 Sets the frequency of the wave table oscillator.
Public function void

SetSampleRate ( const float InSampleRate
)

 Sets the sample rate of the oscillator.
Public function void

SetScaleAdd ( const float InScale,
const float InAdd
)

 Sets the amount to scale and add to the output of the wave table.
Protected function void
