Hello there everyone…i am new to matlab and i have some enquiry regarding time delay…let's say i have a .wav file which consists of my voice (will be using wavread to read the wav file). is there any way i can implement a time delay like for instance:
original signal s(t) delayed version s(t-T), where T=delay
any ideas for implementing s(t-T)? any help or advice will be greatly appreciated!
