Hey guys, in the mirbrightness docs the options accidentally describe mirrolloff (copy and paste error). PDF page 102: mirrolloff(..., 'CutOff’, f) specifies the frequency cut-off, in Hz. Default value: 1500 Hz. The value 1000 Hz has been proposed in (Laukka, Juslin and Bresin, 2005), and the value of 3000 Hz has been proposed in (Juslin, 2000). This should be: mirbrightness(...
