Problem with white noise and wav file
显示 更早的评论
[x, fs ] = wavread('hola.wav');
t = 0:1/fs:1;
% Genera Ruido blanco
L = length(t);
var = 2; % varianza
k = randn(1,L); % ruido no uniforme
mean1 = 0.0; % media
ruido = mean1 + sqrt(var)*k; % ruido blanco
x=ruido;
what is the problem? It will no audio signal with the noise but there is only noise, as is done to be both simultaneously I hope answers thank you

It looks like you're doing:
signal = valid_data_read_from_file;
noise = randomly_generated_noise;
signal = noise; % remove the signal entirely and replace it with noise
You should be doing
signal = signal + noise;
