Adding white noise to an audio signal to obtain a targeted SNR

Hi, I have an audio signal with an SNR of about 100db. My goal is to get multiple version of that signal with different targeted SNR levels: would like to have one version with an SNR of 99.5 db, and another one with 99db and again at 98db and so on. how can I generate this noise and add it to get the targeted SNR

you can try with this code. [ Output_noisy_signal, noise_value ] = generate_noisy( inp_signal, noise_value, snr );
