// 'send' copies samples from the sample stream and proactively pushes those samples to external
//  functions by calling them.  As such, the call and parameters are somewhat specific to the
//  need for the data.  Nevertheless, this code is written in somewhat of a generic form to
//  facilitate adding additional functions in the future.
