| 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< Type >::AudioBuffer | ( | Type *const * | dataToReferTo, |

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.
| dataToReferTo | a 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. |

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.
This will mark the buffer as not cleared and the hasBeenCleared method will return false after this call. If you retain this write pointer and write some data to the buffer after calling its clear method, subsequent clear calls will do nothing. To avoid this either call this method each time you need to write data, or use the setNotClear method to force the internal cleared flag to false.

| 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.
Note that if keepExistingContent and avoidReallocating are both true, then it will only avoid reallocating if neither the channel count or length in samples increase.
If the required memory can't be allocated, this will throw a std::bad_alloc exception.
| newNumChannels | the new number of channels. |
| newNumSamples | the new number of samples. |
| keepExistingContent | if this is true, it will try to preserve as much of the old data as it can in the new buffer. |
| clearExtraSpace | if this is true, then any extra channels or space that is allocated will be also be cleared. If false, then this space is left uninitialised. |
| avoidReallocating | if this 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. |

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.

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

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 is quick, but it may return false negatives when in fact the buffer is still empty.

noexcept |
Forces the internal cleared flag of the buffer to false.
This may be useful in the case where you are holding on to a write pointer and call the clear method before writing some data. You can then use this method to mark the buffer as containing data so that subsequent clear calls will succeed. However a better solution is to call getWritePointer each time you need to write data.

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.
