itdc - compares HRTF ITD modeling techniques. itdc( map, itd, r, graph, style ) Parameters: map az,el indices (default = newgrid(30,18,180,-180, 90,-90)) itd measured ITD data r range (default = 1m) graph measured, arc model, dist model (default = '111') style measured plot style (default = '-ob') Warning! Use newmap() if map read from Snapshot archive. Snapshot archive maps are floating-point; itdc() expects integer. This function is based on a similar function from the paper: Miller, Joel D., "Modeling Interaural Time Difference Assuming a Spherical Head", Music 150, Musical Acoustics, Stanford University, December 2, 2001. http://www.sonisphere.com/SLAB/MUS150Paper.pdf The author has allowed this function to be included in the slab3d release.
