Steganography: Hide secret messages or files in pictures. DCT/FFT Watermark Signal SS Decoder nsign Spectrum Image Steganography, IEEE Transactions on Image Processing, vol. An important consideration will be whether or not you want to hide the string into an existing audio file (so it sounds like a normal file, but has an encoded message -- that is called steganography), or whether you will just be creating a file that sounds like gibberish, for the purpose of encoding data only. This project is a Docker image useful for solving Steganography challenges as those you can find at CTF platforms like hackthebox. It extracts the encrypted secret image from the stego image. While the general Fast Fourier transform (FFT) algorithm computes evenly across the bandwidth of the incoming signal, the Goertzel algorithm looks at specific, predetermined frequency.

The method in [ first employs a low complexity in order to find the transmitted signal candidate that maximizes the log likelihood function, that is the maximum likelihood sequence (MLS). When the multiple access scheme relies on the use of multicarrier signals, and if what is important is how the signal is modulated/demodulated, or "hardware" aspects in the transmitter or the receiver to produce or recover (like synchronisation) such signal or aspects related to the peak power reduction, then the classes under H04L 27/2601 are relevant.
