The separation matrix is expressed as a file in HGTF format with SM sub chunks. The sound source separation transfer function file is designated in the property INITW_FILENAME of GHDSS . Moreover, a separation matrix file is output by designating EXPORT_W_FILENAME, which appears when EXPORT_W is set to true. For details of usage, see GHDSS . Table 5.6 shows the definition of SM sub chunks. The rows in memory of a multi-dimensional array are row major (same as the case of C language).
