Divide an input signal S into n consecutive blocks S i ( i ∈ { 1, …, n }) of length l each. Compute magnitude A i and phase ϕ i of each block using FFT where A (i)=abs (fft (S {i})) and Phi (i)=angle (fft (S {i})) in MATLAB. For example, here are the first 3 elements of ϕ:

In phase coding, the phase of an initial audio segment is substituted with a reference phase that represents the data. Following segments phase is modified back to coding, when applicable, is one of the most efficient audio steganographic methods in terms of the signal to noise ratio (SNR). When the phase relation between each

ing, spread spectrum coding, phase coding, echo data hiding, etc [1]. To hide information within audio signals, [9][10] have designed a steganographic algorithm by manipulating higher LSB layers of the audio signal. Phase alteration and spread spectrum are used in [11][12]; wavelet coding is used in [13][14] and magnitude-based data hiding was proposed by
