Hey guys. I'm an EE student stuck on a stupid problem for DSP. I have a voice recording that I made using the wavrecord function. Its a single vector of values (VERY long) named y. Now my problem is how do I reverse the time on it, when the timing vector is already embedded? Reversing the plot is no problem:

%original plot

tt= 0:9.0704e-5:6.5;
plot(tt,y)

%time reversed:

minus_tt= 7.5-tt;
plot(minus_tt,y)

My requirement is to wavwrite this file as a .wav. Therefore I should be able to use the normal tt with the modified signal. Help please :D
