The Fourier Transform preserves energy, i.e. the transform has the same exact energy as the signal does in the time domain. You can then find the energy of each frequency bin by multiplying its value with its complex conjugate. Signal power represents how quickly it delivers energy. In the context of audio it correlates with how loud the sound ...

Energy of audio signal. Ask Question Asked 1 year, 8 months ago. Active 1 year, 8 months ago. Viewed 165 times 0 $\begingroup$ From audio file [y,FS]=something.wav. So the y is typically N cross 2 matrix . I want calculate energy so i.e sum(abs(y.^2)) So when I apply these I end with two answer for each column. ...
