dtmf_testing.m

% This srcipt test DTMF-function with 12 different audio signals and writes
% "dtmf_X.log" file, where X is your teams name.
% You need dtmf_TESTI_[101,..,112].wav.
% 
% Write your own dtmf_decode.m function with takes .wav-file as input and
% returns characterline of the numbers/spaces like '555 9999 434343434'
% (class(numberLine) --> 'char'; num2str(112) -> '112').

f_h  = @dtmf_decode;        % Change you function name here
teamName = 'DTMF group 6';        % Change your teams name here
