Detailed Description

A chain of audio processors that processes audio sequentially.

This class allows adding multiple audio processors and processes the audio through each processor in the chain.

Constructor & Destructor Documentation

AudioProcessorChain()

sfFDN::AudioProcessorChain::AudioProcessorChain

(

uint32_t

block_size

)

Constructs an AudioProcessorChain with a specified block size.

Parameters

block_size

The size of the audio blocks to process.

Note

The block size is used to allocate internal buffers for processing.

Member Function Documentation

AddProcessor()

bool sfFDN::AudioProcessorChain::AddProcessor

(

std::unique_ptr< AudioProcessor > &&

processor

)

Adds an audio processor to the chain.

Parameters

processor

A unique pointer to the audio processor to add.

Returns

True if the processor was added successfully, false if the output channel count of the last processor does not match the input channel count of the new processor.

Clear()

void sfFDN::AudioProcessorChain::Clear ( )

overridevirtual

Clears the internal state of all processors in the chain.

Implements sfFDN::AudioProcessor.

Clone()

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

overridevirtual

Creates a copy of the audio processor chain.

Returns

A unique pointer to the cloned audio processor chain.

Implements sfFDN::AudioProcessor.

GetProcessor()

AudioProcessor * sfFDN::AudioProcessorChain::GetProcessor

(

uint32_t

index

)

const

Returns a pointer to the processor at the specified index.

Parameters

index

The index of the processor to retrieve.

Returns

A pointer to the processor at the specified index, or nullptr if the index is out of range.

GetProcessorCount()

uint32_t sfFDN::AudioProcessorChain::GetProcessorCount

(

)

const

Returns the number of processors in the chain.

Returns

The number of processors in the chain.

InputChannelCount()

uint32_t sfFDN::AudioProcessorChain::InputChannelCount ( ) const

overridevirtual

Returns the number of input channels this processor expects.

Implements sfFDN::AudioProcessor.

OutputChannelCount()

uint32_t sfFDN::AudioProcessorChain::OutputChannelCount ( ) const

overridevirtual

Returns the number of output channels this processor produces.

Implements sfFDN::AudioProcessor.

Process()

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

overridevirtualnoexcept

Processes the audio buffers through the chain.

Parameters

input	The input audio buffer.
output	The output audio buffer.

Note

The input and output buffers must have the same sample count.

The input buffer's channel count must match the first processor's input channel count, and the output buffer's channel count must match the last processor's output channel count.

The sample count of the input and output buffers must match the block size specified during construction.

Implements sfFDN::AudioProcessor.
