Reverberation Time
显示 更早的评论
trying to design a T60 measurement function. I think i've worked it out but every time i run the function it crashes Matlab. I must have an infinite loop or using a very inefficient way of calculating the t60 but i can't see why it's not working. Any help would be much appreciated thank you
function [ T60Plot ] = T60Plot(input,Fs)
%UNTITLED3 Summary of this function goes here
% Detailed explanation goes here
modInput=sqrt(input.^2);
L=length(input);
maxA = cumsum(modInput);
invertModInput = modInput';
for n = 1:L; n1 = 0;
if 20*log10(sum(modInput(n:L))./maxA)<=-60;
n1 = n1;
else
n1 = n1+1;
end
end
T60Plot = n1/Fs;
end

Do not use the same output variable name as your function name.

You set n1 to 0 each iteration through the "for" loop. The "n1" after the iteration of a loop is thus always going to be 0 or 1. Then you go on to the next iteration, overwriting n1. The result would be the same as if your "for" went from L:L instead of 1:L .
