To compute the PSNR, the block first calculates the mean-squared error using the following equation: M S E = ∑ M , N [ I 1 ( m , n ) − I 2 ( m , n ) ] 2 M * N In the …
PSNR for audio signal in matlab - Stack Overflow
https://stackoverflow.com/questions/22935900/psnr-for-audio-signal-in-matlab
I am trying to find out the values of MSE and PSNR for audio files in my project. The code i have written so far is as follows: [y1,fs1, nbits1,opts1]=wavread ('one.wav'); [y2,fs2, nbits2,opts2]=wavread ('newOne.wav'); [c1x,c1y]=size (y1); [c2x,c2y]=size (y1); if c1x ~= c2x disp ('dimeonsions do not agree'); else R=c1x; C=c1y; err = ( ( (y1-y2).^2)/ (R*C)); MSE=sqrt (err); …

PSNR value is 43.862955653517126 dB. PSNR is most commonly used to estimate the efficiency of compressors, filters, etc. The larger the value of PSNR, the more efficient is a corresponding compression or filter method. My Personal Notes arrow_drop_up.

s=temp (1,; N=length (s); [temp,f]=wavread ('voice2.wav'); temp=temp'; s (2, =temp (1,1:N); i mix them and then using fastICA i get back the unmixed signs. I study 4 cases. 2,3,4 and 5 microphones and i'm trying to find if the increase of mics gives better results (higher psnr).
