~ConverterImplCoreAudio ()
std::pair< size_t, size_t >
convert (const Buffer *sourceBuffer, Buffer *destBuffer) override
Converts up to getSourceMaxFramesPerBlock() frames of audio data from sourceBuffer into destBuffer . Returns a std::pair<num source frames used, num dest frames written>

destBuffer must be large enough to complete the conversion, which is calculated as:
```
minNumDestFrames = min( sourceBuffer->getNumFrames, getSourceMaxFramesPerBlock() ) * getDestSampleRate() / getSourceSampleRate() 
```
void

clear () override

Clears the state of the converter, discarding / flushing accumulated samples. Optional for implementations.

create (size_t sourceSampleRate, size_t destSampleRate, size_t sourceNumChannels, size_t destNumChannels, size_t sourceMaxFramesPerBlock)

If destSampleRate is 0, it is set to match sourceSampleRate . If destNumChannels is 0, it is set to match sourceNumChannels .
