9 % The frequency in the temporal profile, that we are interested in | |
10 pitchstrength.target_frequency=0; % if zero, then look for the highest pitch strength on your own! | |
11 % if we have a target frequency, then the found frequency can deviate by so much: | |
12 pitchstrength.allowed_frequency_deviation=1.12; %two halftones | |

14 % how long the temporal profiles are averaged to get the peak | |
15 pitchstrength.tip_average_time=0.05; % in sec (50 ms) | |
16 pitchstrength.low_pass_frequency=1000; % Hz is used in the logarithmic(!) tip for averaging | |

25 pitchstrength.start_frequency_integration=0.2; % start the ratio calculation at a region at 20% of the maximum | |
