Audio Signal Processing in MATLAB. The Audio Signal Processing group at IEM is, in particular, concentrating on sound analysis, sound modeling, and the extraction of musical or speech-relevant features and characteristics. The topic comprises methods of time-frequency processing, multi-rate processing, and adaptive filtering.

“antennas” in this project. Note that USB is only needed to provide power; the audio signal itself is transmitted over the 3.5mm audio jack cable. First, connect the USB connector to the computer (on the left side of the monitor) and then, connect the audio jack to the computer (also on the left side of the monitor).

Measure the Power of a Signal - MATLAB & Simulink
https://www.mathworks.com/help/signal/ug/measure-the-power-of-a-signal.html
The power of a signal is the sum of the absolute squares of its time-domain samples divided by the signal length, or, equivalently, the square of its RMS level. The function bandpower allows you to estimate signal power in one step. Consider a unit chirp embedded in white Gaussian noise and sampled at 1 kHz for 1.2 seconds.

The Matlab function int needs a symbolic expression as an integrand, and a symbolic variable as an integration variable. In your example s and t are both vectors, and you can't use int in this case. If you want to compute the power or energy of discrete time signals, then you need to use the corresponding definitions:
