def __init__(self, d):
if type(d) is int:

vanne02135 / rt60.m
Created February 11, 2010 21:18
Matlab function to determine RT60 reverberation time from burst signals. Works at least with 2 of my recorded samples of clapping hands.
function r = rt60(s, Fs)
% rt60 (s, Fs) : determine reverberation time from signal s with sampling
% frequency Fs (44100 Hz for most wav's).
t = (0:(length(s)-1))'/Fs;
dt = 1/Fs;
s2 = abs(s);
s2 = s.^2;
s2db = 10*log10(s2/max(s2));
