显示 更早的评论
Dear community,
Is there a way to insert timed pauses (say 1s pause) into an audio array in MATLAB?

Hi Mengjia,
You can use array concatenation to introduce pauses into an audio array.
Assuming you need to have a 1s pause and you will have Fs number of samples in one second (Fs is the sampling frequency), refer the following script for an example,
load gong.mat
% Fs -> Sampling Frequency
% y -> Audio data
% A 1 second pause, in one second you will have Fs number of samples
pause = zeros(Fs,1);
% New array Y
Y = [y(1:4201);pause;y(4202:end)]; % Array concatenation
sound(Y)
