Detailed Description

template<typename T>
class switchboard::AudioBufferPool< T >

Allocates memory for multiple AudioBuffer instances.

AudioBufferPool class.

This class can be used to avoid allocations on the real-time audio thread by pre-allocating enough memory for the audio buffers. Only supports non-interleaved buffers.

Constructor & Destructor Documentation

AudioBufferPool()

template<typename T >

switchboard::AudioBufferPool< T >::AudioBufferPool	(	const uint	maxNumberOfBuffers,
		const uint	maxNumberOfChannels,
		const uint	maxNumberOfFrames )

Creates an AudioBufferPool instance.

Parameters

maxNumberOfBuffers	Maximum number of AudioBuffer instances that can be taked from the pool.
maxNumberOfChannels	Maximum number of channels for each audio buffer.
maxNumberOfFrames	Maximum number of channels for each audio buffer.
