Detailed Description

Implements a sparse FIR filter.

Member Function Documentation

Clear()

void sfFDN::SparseFir::Clear ( )

overridevirtual

Clears the internal state of the processor.

This function resets the internal state of the filter to zero.

Implements sfFDN::AudioProcessor.

Clone()

std::unique_ptr< AudioProcessor > sfFDN::SparseFir::Clone ( ) const

overridevirtual

Creates a copy of the filter.

Returns

A unique pointer to the cloned filter.

Implements sfFDN::AudioProcessor.

InputChannelCount()

uint32_t sfFDN::SparseFir::InputChannelCount ( ) const

overridevirtual

Returns the number of input channels supported by this processor.

Returns

The number of input channels.

Implements sfFDN::AudioProcessor.

OutputChannelCount()

uint32_t sfFDN::SparseFir::OutputChannelCount ( ) const

overridevirtual

Returns the number of output channels produced by this processor.

Returns

The number of output channels.

Implements sfFDN::AudioProcessor.

Process()

void sfFDN::SparseFir::Process ( const AudioBuffer & input, AudioBuffer & output )

overridevirtualnoexcept

Processes a block of input samples through the filter.

Parameters

input	The input audio buffer.
output	The output audio buffer. The input and output buffers must have the same number of channels and sample count.

Implements sfFDN::AudioProcessor.

SetCoefficients()

void sfFDN::SparseFir::SetCoefficients

(

const SparseFirOptions &

config = {}

)

Sets the FIR coefficients.

Parameters

config

The FIR coefficients.

Tick()

float sfFDN::SparseFir::Tick

(

float

in

)

Input a sample in the filter and return the next output.

Parameters

in	The input sample

Returns

The next output sample
