Generating an Echo for an Audio Signal using Convolution
显示 更早的评论
[y,Fs] = audioread('Test1.wav');
delay=0.8*Fs; %Delay
attenuation_factor=0.4;
h=zeros(1,delay);%Impulse
h(delay)=attenuation_factor; %Impulse at delay
z=conv(y,h); %Convolution
sound(z,Fs)
The produced sound doesn't include the desired echo, and not sure why so. I would apprechiate the help

z is simply the delayed input (echo). You forgot to add echo to the input! You are listening to the echo component only, not sound + echo
