Enhancing Audio Steganography: Comparing Affine & Hill Ciphers for Secure Data Embedding 🔐

This work encrypts the text information using affine and hill cipher method before embedding it into audio signal using LSB method. Then comparison is been made between both the cipher methods on the basis of PSNR( Peak signal to noise ratio), MSE( Mean square error), Time taken to embed the information using both cipher in combination with audio steganography, Frequency representations of both methods.
