1 function test_toneInNoise | |
2 % test_MAP1_14 is a general purpose test routine that can be adjusted to | |
3 % test a number of different applications of MAP1_14 | |
4 % | |
5 % A range of options are supplied in the early part of the program | |
6 % | |
7 % One use of the function is to create demonstrations; filenames <demoxx> | |
8 % to illustrate particular features | |
9 % | |
10 % #1 | |
11 % Identify the file (in 'MAPparamsName') containing the model parameters | |
12 % | |
13 % #2 | |
14 % Identify the kind of model required (in 'AN_spikesOrProbability'). | |
15 % A full brainstem model (spikes) can be computed or a shorter model | |
16 % (probability) that computes only so far as the auditory nerve | |
17 % | |
18 % #3 | |
19 % Choose between a tone signal or file input (in 'signalType') | |
20 % | |
21 % #4 | |
22 % Set the signal rms level (in leveldBSPL) | |
23 % | |
24 % #5 | |
25 % Identify the channels in terms of their best frequencies in the vector | |
26 % BFlist. | |
27 % | |
28 % Last minute changes to the parameters fetched earlier can be made using | |
29 % the cell array of strings 'paramChanges'. | |
30 % Each string must have the same format as the corresponding line in the | |
31 % file identified in 'MAPparamsName' | |
32 % | |
33 % When the demonstration is satisfactory, freeze it by renaming it <demoxx> | |
