Generate one convolution filter for that speaker for each sampling frequency (rate) you will need making sure you increase number of taps in powers of two as the sampling frequency gets higher. The mathematical operation of scaling and summing these individual impulse responses to generate the tissue contrast concentration curve c(t) is known as convolution. For good reverb: echo density (echoes per second) must increase as time goes on response should be quasi-random (no spectral coloration) high frequencies typically decay faster than low frequencies Reverb Simulation (cont.) echo_signal(ds+(1:length(in*gain)))=in*gain; % Calculate the number of points for the given delay, % Pad the original signal with zeros to make room for the echo, % Create an echo signal that starts with 0's, % the abs of all values must be < 1.
