Class AudioDeviceRenderCallback

include/LabSound/core/AudioDevice.h:75–91

`render()` is called periodically to get the next render quantum of audio into destinationBus. Optional audio input is given in src (if not nullptr). This structure also keeps track of timing information with respect to the callback.
