Converter /

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() 

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

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