Hi,
I wanted to ask if there is a way to add gain to an audio signal using MATLAB?
For ex., I have an audio file, and I want to add ~30dB gain to the signal. How can I do that?

Try this —
Fs = 44100; t = linspace(0, Fs-1, Fs)/Fs; s1 = sin(2*pi*t*15); dB30 = db2mag(30)
dB30 = 31.6228
s2 = s1*dB30; figure plot(t, s1, 'DisplayName','Original') hold on plot(t, s2, 'DisplayName','Original With 30 dB Amplification') hold off grid legend('Location','best')
