Hi,
I have an audio signal which has 44.1 KHz sampling rate, which would be stored as an array. I am trying to find energy for each second using:
sum(x.^2);
Can someone help me how to do that? Thanks

Fs = 44.1E+3; % Sampling Frequency
s = randn(Fs*5.2,1); % Signal
seconds_sampled = 1; % Desired Smaple Length
sec1 = Fs*seconds_sampled; % Corresponding Samples
s_sections = buffer(s,sec1)
Check = size(s_sections)
Energy = sum(s_sections.^2)
.
