Conclusion

Table 1. shows the difference between RSA, PlayFair and Noble Prime encrypt/decrypt .

File Name :  anna.wav

Size           :  828.934 bytes

Play Time  : 18,794 seconds.

Mode         :  PCM  44100 Hz  8 bit Mono (Unsigned)

                                                           Table 1.

Findings:  

-         Edwave  : If the encrypted audio is listened, it can be seen that there is only noise.

-         Rsawave :  This algorithm is added 80 % noise in audio. Original sound is a little bit recognizable.

-         Playwave : This algorithm is added a little bit of noise. Almost everything is heard. Can't be used in audio encryption.

At the end we can say that the best algorithm is Noble Prime Encryption.
