hlab - HRTF Lab, HRTF analysis and visualization application. hlab( s1, s2 ) s1: slab3d archive struct 1 (required) s2: slab3d archive struct 2 (optional) hlab() provides a graphical user interface for the command-line utilities vir(), vall(), hen(), and vitd(). When viewing two sarcs, if an ITD is displayed above the figure, it is the ITD of HRTF 2. When loading CIPIC sarcs, use s1. s1 includes the NearGrid feature that maps the CIPIC grid to a fixed-increment grid. The distance from the actual CIPIC grid location to the "near grid" location is shown in cm's assuming a 1m radius sphere. This feature is for comparing CIPIC sarcs to fixed-grid sarcs. If not comparing to other sarcs, the GRID slider can be used to increment through the HRTF locations. The locations are ordered el-grouped-by-az in CIPIC coordinates. The values displayed on the screen, however, are in slab3d coordinates. To visualize this mapping, run cgrid(). See also: vir(), vall(), hen(), cgrid(), vitd()
