Shifts the Buffer data to the left, to make room for new Source data and copies Source to the Buffer. BufferSize defines the maximum size up to which the Buffer will increase and before the shifting begins. When BufferSizse is exceeded the oldest data is dropped to make space for the new. 

Note This function is not very efficient for very big buffers, but it is very simple to use.
