The FX Engine treats individual 8 second sub-observations as independent work units. Most of its mode settings are able to change on-the-fly from one sub-observation to the next.  Each 8 second sub-observation file contains 160 blocks of 50 ms of input data each.   An additional block of metadata (of the same size as a 50 ms data block) is prepended to the data blocks, making a total of 161 blocks per sub-observation file.  At the start of processing each new sub-observation file, the metadata block is parsed to configure the operating parameters for the following 160 data blocks.
