fprintf('Choose integer M \n')
grid on ;
I would like to make an inquiry, who can help me, I appreciate it. I'm doing the downsampling effect on an audio signal with an integer M factor for example 2 to make the a acute voice. The problem is the following, my original audio has a certain sampling frequency, a number of samples and a duration for example of 10 sec. When applying the dowsampling effect with a reduction factor of M = 2, the audio time is reduced to 5 seconds. There is some way in matlab to make the high-pitched voice effect as it happens to me here but keeping 10 seconds of the original audio?
I leave my program Thank you very much to all!
