Functions

  Type Name Description
Public function void Clears memory without reevaluating coefficients.
Public function Const float  
Public function void

Init ( float InSampleRate,
int32 InNumChannels
)

  
Public function void

ProcessAudioBuffer ( const float*__restrict InputBuffer,
float*__restrict OutputBuffer,
const int32 NumSamples
)

 Interpolates coefficient and processes a buffer
Public function void

ProcessAudioFrame ( const float*__restrict InputFrame,
float*__restrict OutputFrame
)

 Interpolates coefficient and processes a sample
Public function void

Reset ()

 Resets the sample delay to 0.
Public function void

StartFrequencyInterpolation ( const float InTargetFrequency,
const int32 InterpLength
)

 StartFrequencyInterpolation(): Intended use: call once at the beginning of callback, pass the callback length then call ProcessAudioFrame() exactly "InterpLength" number of times At the end of the callback, call StopFrequencyInterpolation()
Public function void StopFrequencyInterpolation() needs to be called manually when the interpolation should be done.
