The frequency at which "doGetNextFrame()" gets called depends entirely on the
value that you set for "fDurationInMicroseconds". If you set this appropriately
i.e., fDurationInMicroseconds =
(numSamplesDelivered*1000000)/samplesPerSecond
then "doGetNextFrame()" will get called at the appropriate frequency.
Alternatively, if you leave "fDurationInMicroseconds" at its default value of
zero, then "doGetNextFrame()" will get called again immediately after you
complete delivery of the previous frame, but that's OK, provided that you don't
actually complete the delivery (i.e., call "FramedSource::afterGetting()")
until you have accumulated however many samples you want to deliver each time.
(Of course, you shouldn't 'block' or 'spin' waiting for this to happen.)
