     Featured in both tasks, the NOTSOFAR recorded meeting dataset is leveraged as a common benchmark: 
     each geometry-agnostic MC system submitted to DASR tracks (constrained or not) will also be **automatically submitted** 
     to the known-geometry single-device NOTSOFAR-MC track. These entries will be marked with "DASR" to denote their origin.
