FInterpolatedHPF::StartFrequencyInterpolation

[StartFrequencyInterpolation()](API\Runtime\SignalProcessing\DSP\FInterpolatedHPF\StartFrequencyInterpolation): Intended use: call once at the beginning of callback, pass the callback length then call [ProcessAudioFrame()](API\Runtime\SignalProcessing\DSP\FInterpolatedHPF\ProcessAudioFrame) exactly "InterpLength" number of times At the end of the callback, call [StopFrequencyInterpolation()](API\Runtime\SignalProcessing\DSP\FInterpolatedHPF\StopFrequencyInterpolation)

Remarks

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()

Failing to call StopFrequencyInterpolation() after more than InterpLength calls to ProcessAudioFrame will cause the filter to become unstable and blow up to +/- inf!
