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

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 …
Peak signal-to-noise ratio - Wikipedia
https://en.wikipedia.org/wiki/Peak_signal-to-noise_ratio
Peak signal-to-noise ratio is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. Because many signals have a very wide dynamic range, PSNR is usually expressed as a logarithmic quantity using the decibel scale. PSNR is commonly used to quantify …

PSNR for Audio Steganography using LSB algorithm
https://in.mathworks.com/matlabcentral/answers/299954-psnr-for-audio-steganography-using-lsb-algorithm
PSNR for audio steganography is the same as PSNR for any other audio application, which in turn is the same as PSNR for any other purpose.
how to calculate mse and psnr of compressed audio?
https://www.mathworks.com/matlabcentral/answers/322788-how-to-calculate-mse-and-psnr-of-compressed-audio
Assuming that you have a reference signal and another compressed one, you can use the inbuilt MATLAB functions to calculate both MSE and PSNR of the two audio signals. It might help to refer to the MATLAB documentation for the same:
Python | Peak Signal-to-Noise Ratio (PSNR) - GeeksforGeeks
https://www.geeksforgeeks.org/python-peak-signal-to-noise-ratio-psnr/
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.

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.
