lets say i have an audio that has so many different frequencies, can i modify its frequency to constant and run it at 2000 hz for example?

load handel.mat
[p, q] = rat(2000/Fs)
y2000 = resample(y, p, q);
whos

load handel.mat % load a sample data with Fs
[p, q] = rat(2000/Fs) % find a rational fraction of desired Fs and orighinal Fs
% p, q are integers so that resample can be efficiently implemented
y2000 = resample(y, p, q); % resample the data so that FsNew = p/q*Fs
