Comparing these two audio files

I have two audio files, one of which is the original file, and the other I ruined it by changing some bits, how to compare the quality of these two files - is there any algorithm or software where I can compare the quality of the two files,

"any algorithm or an software": Do you want to program or not?

  • If you want software to do this for you: stackoverflow can't help you

  • If you want to program (at least call functions in the library) another story:

, , , WAVEFORM ( , ). ? . ( , , * 16- 22 ), : , , - , up: , : - ( ); * 16- , C int, A) , B) .

SNR: http://en.wikipedia.org/wiki/Signal-to-noise_ratio. lib, , :

  • : [n] = [n] - [n], n =
  • "" "": p_noise [n] = [n] * noise [n],...
  • SNR, = SNR [n] = p_original [n]/p_noise [n]

(!) SNR... , , . .
