    how to calculate PSNR of audio files using MATLAB

    @ Mariach:- From code snipplet it is evident that you are reading two signal as voice1.wav & voice2.wav. From Later steps it is clear , "s" is your signal which is mixed. Since your code snipplet used temp variable to store original signal data, so in technical sense , original signal has been...
