Detailed Description

template<class SampleType, Interp::TypeCode InterpTypeCode = Interp::Linear>
class HPFUnit< SampleType, InterpTypeCode >

Butterworth 2nd-order high-pass filter.

This has good linearity in the passband.

Factory functions:

• ar (input, frequency=1200, mul=1, add=0, preferredBlockSize=default, preferredSampleRate=default)
• kr (input frequency=1200, mul=1, add=0)

Inputs:

• input: (unit, multi) the unit to filter
• frequency: (unit, multi) the -3dB point cut-off frequency in Hz
• mul: (unit, multi) the multiplier applied to the output
• add: (unit, multi) the offset aded to the output
• preferredBlockSize: the preferred output block size (for advanced usage, leave on default if unsure)
• preferredSampleRate: the preferred output sample rate (for advanced usage, leave on default if unsure)
