function test_toneInNoise % test_MAP1_14 is a general purpose test routine that can be adjusted to % test a number of different applications of MAP1_14 % % A range of options are supplied in the early part of the program % % One use of the function is to create demonstrations; filenames <demoxx> % to illustrate particular features % % #1 % Identify the file (in 'MAPparamsName') containing the model parameters % % #2 % Identify the kind of model required (in 'AN_spikesOrProbability'). % A full brainstem model (spikes) can be computed or a shorter model % (probability) that computes only so far as the auditory nerve % % #3 % Choose between a tone signal or file input (in 'signalType') % % #4 % Set the signal rms level (in leveldBSPL) % % #5 % Identify the channels in terms of their best frequencies in the vector % BFlist. % % Last minute changes to the parameters fetched earlier can be made using % the cell array of strings 'paramChanges'. % Each string must have the same format as the corresponding line in the % file identified in 'MAPparamsName' % % When the demonstration is satisfactory, freeze it by renaming it <demoxx> global dt dtSpikes savedBFlist saveAN_spikesOrProbability saveMAPparamsName... savedInputSignal OMEextEarPressure TMoutput OMEoutput ARattenuation ...
