Time shift a signal and save the new signal

I have two signals. one is a clean speech signal and the other is an egg signal.

The speech signal is a bit late. So I want to shift the speech signal to start at the same time as the egg and save this new signal. is that possible?

Ive attached the two signals here. Any insights, and ideas will be appreciated.

hello

I am intrigued that you want to shift one and not both signals or maybe (and this is what I would assume) you simply want to remove the same amount of initial samples on both signals

once you have loaded th wav files (with audioread) , you can simply remove the required amount of signals by doing (on both data sets) :

data(1:samples) = []; % samples = Fs*start_time I want
