Audio scrambler
An audio scrambler is created to enhance the security during audio signal transmission. The audio signal is transformed by Short-time Fourier transform and scrambled in frequency domain. The scrambled audio signal is decrypted on the receiver side. To test the quality of audio scrambler, three types...
