Constructor & Destructor Documentation

◆ AudioBuffer() [1/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( )
noexcept

Creates an empty buffer with 0 channels and 0 length.

◆ AudioBuffer() [2/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( int  numChannelsToAllocate,
int  numSamplesToAllocate 
)

Creates a buffer with a specified number of channels and samples.

The contents of the buffer will initially be undefined, so use clear() to set all the samples to zero.

The buffer will allocate its memory internally, and this will be released when the buffer is deleted. If the memory can't be allocated, this will throw a std::bad_alloc exception.

◆ AudioBuffer() [3/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( Type *const *  dataToReferTo,
int  numChannelsToUse,
int  numSamples 
)

Creates a buffer using a pre-allocated block of memory.

Note that if the buffer is resized or its number of channels is changed, it will re-allocate memory internally and copy the existing data to this new area, so it will then stop directly addressing this memory.

Parameters
dataToReferToa pre-allocated array containing pointers to the data for each channel that should be used by this buffer. The buffer will only refer to this memory, it won't try to delete it when the buffer is deleted or resized.
numChannelsToUsethe number of channels to use - this must correspond to the number of elements in the array passed in
numSamplesthe number of samples to use - this must correspond to the size of the arrays passed in

◆ AudioBuffer() [4/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( Type *const *  dataToReferTo,
int  numChannelsToUse,
int  startSample,
int  numSamples 
)

Creates a buffer using a pre-allocated block of memory.

Note that if the buffer is resized or its number of channels is changed, it will re-allocate memory internally and copy the existing data to this new area, so it will then stop directly addressing this memory.

Parameters
dataToReferToa pre-allocated array containing pointers to the data for each channel that should be used by this buffer. The buffer will only refer to this memory, it won't try to delete it when the buffer is deleted or resized.
numChannelsToUsethe number of channels to use - this must correspond to the number of elements in the array passed in
startSamplethe offset within the arrays at which the data begins
numSamplesthe number of samples to use - this must correspond to the size of the arrays passed in

◆ AudioBuffer() [5/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( const AudioBuffer< Type > &  other)

Copies another buffer.

This buffer will make its own copy of the other's data, unless the buffer was created using an external data buffer, in which case boths buffers will just point to the same shared block of data.

◆ ~AudioBuffer()

template<typename Type>
AudioBuffer< Type >::~AudioBuffer ( )
noexcept

Destructor.

This will free any memory allocated by the buffer.

◆ AudioBuffer() [6/6]

template<typename Type>
AudioBuffer< Type >::AudioBuffer ( AudioBuffer< Type > &&  other)
noexcept

Move constructor.

Member Function Documentation

◆ operator=() [1/2]

template<typename Type>
AudioBuffer& AudioBuffer< Type >::operator= ( const AudioBuffer< Type > &  other)

Copies another buffer onto this one.

This buffer's size will be changed to that of the other buffer.

◆ operator=() [2/2]

template<typename Type>
AudioBuffer& AudioBuffer< Type >::operator= ( AudioBuffer< Type > &&  other)
noexcept

Move assignment.

◆ getNumChannels()

template<typename Type>
int AudioBuffer< Type >::getNumChannels ( ) const
noexcept

Returns the number of channels of audio data that this buffer contains.

◆ getReadPointer() [1/2]

template<typename Type>
const Type* AudioBuffer< Type >::getReadPointer ( int  channelNumber) const
noexcept

Returns a pointer to an array of read-only samples in one of the buffer's channels.

For speed, this doesn't check whether the channel number is out of range, so be careful when using it! If you need to write to the data, do NOT call this method and const_cast the result! Instead, you must call getWritePointer so that the buffer knows you're planning on modifying the data.

◆ getReadPointer() [2/2]

template<typename Type>
const Type* AudioBuffer< Type >::getReadPointer ( int  channelNumber,
int  sampleIndex 
) const
noexcept

Returns a pointer to an array of read-only samples in one of the buffer's channels.

For speed, this doesn't check whether the channel number or index are out of range, so be careful when using it! If you need to write to the data, do NOT call this method and const_cast the result! Instead, you must call getWritePointer so that the buffer knows you're planning on modifying the data.

◆ getWritePointer() [1/2]

template<typename Type>
Type* AudioBuffer< Type >::getWritePointer ( int  channelNumber)
noexcept

Returns a writeable pointer to one of the buffer's channels.

For speed, this doesn't check whether the channel number is out of range, so be careful when using it! Note that if you're not planning on writing to the data, you should always use getReadPointer instead.

Referenced by VST3BufferExchange< float >::associateBufferTo().

◆ getWritePointer() [2/2]

template<typename Type>
Type* AudioBuffer< Type >::getWritePointer ( int  channelNumber,
int  sampleIndex 
)
noexcept

Returns a writeable pointer to one of the buffer's channels.

For speed, this doesn't check whether the channel number or index are out of range, so be careful when using it! Note that if you're not planning on writing to the data, you should use getReadPointer instead.

◆ getArrayOfReadPointers()

template<typename Type>
const Type** AudioBuffer< Type >::getArrayOfReadPointers ( ) const
noexcept

Returns an array of pointers to the channels in the buffer.

Don't modify any of the pointers that are returned, and bear in mind that these will become invalid if the buffer is resized.

◆ getArrayOfWritePointers()

template<typename Type>
Type** AudioBuffer< Type >::getArrayOfWritePointers ( )
noexcept

Returns an array of pointers to the channels in the buffer.

Don't modify any of the pointers that are returned, and bear in mind that these will become invalid if the buffer is resized.

Referenced by AudioProcessor::getBusBuffer().

◆ setSize()

template<typename Type>
void AudioBuffer< Type >::setSize ( int  newNumChannels,
int  newNumSamples,
bool  keepExistingContent = false,
bool  clearExtraSpace = false,
bool  avoidReallocating = false 
)

Changes the buffer's size or number of channels.

This can expand or contract the buffer's length, and add or remove channels.

If keepExistingContent is true, it will try to preserve as much of the old data as it can in the new buffer.

If clearExtraSpace is true, then any extra channels or space that is allocated will be also be cleared. If false, then this space is left uninitialised.

If avoidReallocating is true, then changing the buffer's size won't reduce the amount of memory that is currently allocated (but it will still increase it if the new size is bigger than the amount it currently has). If this is false, then a new allocation will be done so that the buffer uses takes up the minimum amount of memory that it needs.

If the required memory can't be allocated, this will throw a std::bad_alloc exception.

◆ setDataToReferTo() [1/2]

template<typename Type>
void AudioBuffer< Type >::setDataToReferTo ( Type **  dataToReferTo,
int  newNumChannels,
int  newStartSample,
int  newNumSamples 
)

Makes this buffer point to a pre-allocated set of channel data arrays.

There's also a constructor that lets you specify arrays like this, but this lets you change the channels dynamically.

Note that if the buffer is resized or its number of channels is changed, it will re-allocate memory internally and copy the existing data to this new area, so it will then stop directly addressing this memory.

Parameters
dataToReferToa pre-allocated array containing pointers to the data for each channel that should be used by this buffer. The buffer will only refer to this memory, it won't try to delete it when the buffer is deleted or resized.
newNumChannelsthe number of channels to use - this must correspond to the number of elements in the array passed in
newStartSamplethe offset within the arrays at which the data begins
newNumSamplesthe number of samples to use - this must correspond to the size of the arrays passed in

Referenced by AudioBuffer< float >::setDataToReferTo().

◆ setDataToReferTo() [2/2]

template<typename Type>
void AudioBuffer< Type >::setDataToReferTo ( Type **  dataToReferTo,
int  newNumChannels,
int  newNumSamples 
)

Makes this buffer point to a pre-allocated set of channel data arrays.

There's also a constructor that lets you specify arrays like this, but this lets you change the channels dynamically.

Note that if the buffer is resized or its number of channels is changed, it will re-allocate memory internally and copy the existing data to this new area, so it will then stop directly addressing this memory.

Parameters
dataToReferToa pre-allocated array containing pointers to the data for each channel that should be used by this buffer. The buffer will only refer to this memory, it won't try to delete it when the buffer is deleted or resized.
newNumChannelsthe number of channels to use - this must correspond to the number of elements in the array passed in
newNumSamplesthe number of samples to use - this must correspond to the size of the arrays passed in

◆ makeCopyOf()

template<typename Type>
template<typename OtherType >
void AudioBuffer< Type >::makeCopyOf ( const AudioBuffer< OtherType > &  other,
bool  avoidReallocating = false 
)

Resizes this buffer to match the given one, and copies all of its content across.

The source buffer can contain a different floating point type, so this can be used to convert between 32 and 64 bit float buffer types.

◆ clear() [1/3]

template<typename Type>
void AudioBuffer< Type >::clear ( )
noexcept

◆ clear() [2/3]

template<typename Type>
void AudioBuffer< Type >::clear ( int  startSample,
int  numSamples 
)
noexcept

Clears a specified region of all the channels.

For speed, this doesn't check whether the channel and sample number are in-range, so be careful!

◆ clear() [3/3]

template<typename Type>
void AudioBuffer< Type >::clear ( int  channel,
int  startSample,
int  numSamples 
)
noexcept

Clears a specified region of just one channel.

For speed, this doesn't check whether the channel and sample number are in-range, so be careful!

◆ hasBeenCleared()

template<typename Type>
bool AudioBuffer< Type >::hasBeenCleared ( ) const
noexcept

Returns true if the buffer has been entirely cleared.

Note that this does not actually measure the contents of the buffer - it simply returns a flag that is set when the buffer is cleared, and which is reset whenever functions like getWritePointer() are invoked. That means the method does not take any time, but it may return false negatives when in fact the buffer is still empty.

Referenced by AudioBuffer< float >::makeCopyOf().

◆ getSample()

template<typename Type>
Type AudioBuffer< Type >::getSample ( int  channel,
int  sampleIndex 
) const
noexcept

Returns a sample from the buffer.

The channel and index are not checked - they are expected to be in-range. If not, an assertion will be thrown, but in a release build, you're into 'undefined behaviour' territory.

◆ setSample()

template<typename Type>
void AudioBuffer< Type >::setSample ( int  destChannel,
int  destSample,
Type  newValue 
)
noexcept

Sets a sample in the buffer.

The channel and index are not checked - they are expected to be in-range. If not, an assertion will be thrown, but in a release build, you're into 'undefined behaviour' territory.

◆ addSample()

template<typename Type>
void AudioBuffer< Type >::addSample ( int  destChannel,
int  destSample,
Type  valueToAdd 
)
noexcept

Adds a value to a sample in the buffer.

The channel and index are not checked - they are expected to be in-range. If not, an assertion will be thrown, but in a release build, you're into 'undefined behaviour' territory.

◆ applyGain() [1/3]

template<typename Type>
void AudioBuffer< Type >::applyGain ( int  channel,
int  startSample,
int  numSamples,
Type  gain 
)
noexcept

Applies a gain multiple to a region of one channel.

For speed, this doesn't check whether the channel and sample number are in-range, so be careful!

Referenced by AudioBuffer< float >::applyGain(), and AudioBuffer< float >::applyGainRamp().

◆ applyGain() [2/3]

template<typename Type>
void AudioBuffer< Type >::applyGain ( int  startSample,
int  numSamples,
Type  gain 
)
noexcept

Applies a gain multiple to a region of all the channels.

For speed, this doesn't check whether the sample numbers are in-range, so be careful!

◆ applyGain() [3/3]

template<typename Type>
void AudioBuffer< Type >::applyGain ( Type  gain)
noexcept

Applies a gain multiple to all the audio data.

◆ applyGainRamp() [1/2]

template<typename Type>
void AudioBuffer< Type >::applyGainRamp ( int  channel,
int  startSample,
int  numSamples,
Type  startGain,
Type  endGain 
)
noexcept

Applies a range of gains to a region of a channel.

The gain that is applied to each sample will vary from startGain on the first sample to endGain on the last Sample, so it can be used to do basic fades.

For speed, this doesn't check whether the sample numbers are in-range, so be careful!
