rmeddis@35: function test_speechInNoise
rmeddis@35: % test_MAP1_14 is a general purpose test routine that can be adjusted to

rmeddis@35: % One use of the function is to create demonstrations; filenames <demoxx>

rmeddis@35: %  A full brainstem model (spikes) can be computed or a shorter model
rmeddis@35: %  (probability) that computes only so far as the auditory nerve
rmeddis@35: %
rmeddis@35: % #3
rmeddis@35: % Choose between a tone signal or file input (in 'signalType')
