Audio Peak Signal to Noise Ratio (PSNR) Analysis Peak Signal to Noise Ratio is a comparison between the maximum intensity of the signal over time compared to the noise floor. This can be a useful metric to approximate quality of compression by comparing the source “signal” to the encoded target and reporting how much compression “noise” affected the signal in the output.
PSNR for audio signal in matlab - Stack Overflow
https://stackoverflow.com/questions/22935900/psnr-for-audio-signal-in-matlab
PSNR for audio signal in matlab. Bookmark this question. Show activity on this post. 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 …
How is the quality of audio file when PSNR is more than 48?
https://www.mathworks.com/matlabcentral/answers/521125-how-is-the-quality-of-audio-file-when-psnr-is-more-than-48
PSNR = 20*log10 (MAXVAL/MSE); How can I comment on the result? According to the post here, it says ‘If the reconstructed audio signal is exactly same as original signal then MSE =0. And if Max pixel value is 255 (8-bit representation), then the value of …

Mazdak Technique for PSNR Estimation in Audio Steganography Abstract: A novel method to estimate PSNR of the result of audio steganography before embedding is presented. Estimated PSNR by proposed linear interpolation formula was tested and the result was almost the same with the obtained PSNR in practical way. Access through your institution

So to get PSNR of your "s" signal -> "s" is the orig_signal (Technically , mixed signal) or in other words an referenced signal so you will get 2 cases for psnr :- "s" (original signal) & recovered_voice1(derived ) (though it was actual before implementation of algo.) & other "s" (original signal) & recovered_voice2(derived ) Hope this helps Thanks
Compute peak signal-to-noise ratio (PSNR) between …
https://www.mathworks.com/help/vision/ref/psnr.html
Description. The PSNR block computes the peak signal-to-noise ratio, in decibels, between two images. This ratio is used as a quality measurement between the original and a compressed image. The higher the PSNR, the better the quality of the compressed, or reconstructed image.

Peak signal-to-noise ratio (PSNR) is the ratio between the maximum possible power of an image and the power of corrupting noise that affects the quality of its representation. To estimate the PSNR of an image, it is necessary to compare that image to an ideal clean image with the maximum possible power. PSNR is defined as follows:
