	Frame partitioning method used by SSIGIN=====Notes:=====		Frame partitioning method used by SSIGIN

			=====Notes:=====

	This read function is currently not used, because specialized signal-I/O (analysis/re-synthesis) atoms for the filter methods have been implemented. The values of the outputs <var>SR</var> and <var>N</var> are set during the initialization. The output <var>I</var> is initialized to 0 and incremented by 1 after each read cycle. The input <var>REV</var> can be used to reverse the signal in time.
