Detailed Description

template<typename SampleType>
class dsp::AudioBlock< SampleType >

Minimal and lightweight data-structure which contains a list of pointers to channels containing some kind of sample data.

This class doesn't own any of the data which it points to, it's simply a view into data that is owned elsewhere. You can construct one from some raw data that you've allocated yourself, or give it a HeapBlock to use, or give it an AudioBuffer which it can refer to, but in all cases the user is responsible for making sure that the data doesn't get deleted while there's still an AudioBlock using it.

using dsp::AudioBlock< SampleType >::NumericType = typename SampleTypeHelpers::ElementType<SampleType>::Type

Constructor & Destructor Documentation

◆ AudioBlock() [1/8]

template<typename SampleType>

dsp::AudioBlock< SampleType >::AudioBlock ( )

defaultnoexcept

Create a zero-sized AudioBlock.

◆ AudioBlock() [2/8]

template<typename SampleType>

constexpr dsp::AudioBlock< SampleType >::AudioBlock	(	SampleType const	channelData,
		size_t	numberOfChannels,
		size_t	numberOfSamples
	)

noexcept

Creates an AudioBlock from a pointer to an array of channels.

AudioBlock does not copy nor own the memory pointed to by dataToUse. Therefore it is the user's responsibility to ensure that the memory is retained throughout the life-time of the AudioBlock and released when no longer needed.

◆ AudioBlock() [3/8]

template<typename SampleType>

constexpr dsp::AudioBlock< SampleType >::AudioBlock	(	SampleType const	channelData,
		size_t	numberOfChannels,
		size_t	startSampleIndex,
		size_t	numberOfSamples
	)

noexcept

Creates an AudioBlock from a pointer to an array of channels.

AudioBlock does not copy nor own the memory pointed to by dataToUse. Therefore it is the user's responsibility to ensure that the memory is retained throughout the life-time of the AudioBlock and released when no longer needed.

◆ AudioBlock() [4/8]

template<typename SampleType>

dsp::AudioBlock< SampleType >::AudioBlock	(	HeapBlock< char > &	heapBlockToUseForAllocation,
		size_t	numberOfChannels,
		size_t	numberOfSamples,
		size_t	alignmentInBytes = `defaultAlignment`
	)

noexcept

Allocates a suitable amount of space in a HeapBlock, and initialises this object to point into it.

The HeapBlock must of course not be freed or re-allocated while this object is still in use, because it will be referencing its data.

◆ AudioBlock() [5/8]

template<typename SampleType>

template<typename OtherSampleType >

constexpr dsp::AudioBlock< SampleType >::AudioBlock ( AudioBuffer< OtherSampleType > & buffer )

noexcept

Creates an AudioBlock that points to the data in an AudioBuffer.

AudioBlock does not copy nor own the memory pointed to by dataToUse. Therefore it is the user's responsibility to ensure that the buffer is retained throughout the life-time of the AudioBlock without being modified.

◆ AudioBlock() [6/8]

template<typename SampleType>

template<typename OtherSampleType >

dsp::AudioBlock< SampleType >::AudioBlock	(	AudioBuffer< OtherSampleType > &	buffer,
		size_t	startSampleIndex
	)

noexcept

Creates an AudioBlock that points to the data in an AudioBuffer.

AudioBlock does not copy nor own the memory pointed to by dataToUse. Therefore it is the user's responsibility to ensure that the buffer is retained throughout the life-time of the AudioBlock without being modified.

	)		const

noexcept

Modifies a sample in the buffer.
