Derivative-Based Audio Steganalysis
https://www.shsu.edu/~qxl005/New/Publications/TOMCCAP_audiosteganalysis.pdf
In audio steganalysis, it is expected that a similar relation can be observed between detection performance and the audio’s signal complexity. In this article, we present an approach for audio steganalysis based on the Mel-cepstrum coefficients derived from the second-order derivative to improve Kraetzer and Dittmann’s work. We also extract

The derivative of a sine wave is the cosine, and vice versa. The cosine is just a sine shifted in phase by 90°. All periodic waves can be constructed from the sum of a series of sinewaves of different frequencies and amplitudes (Fourier’s Theorem), and this is the underlying principle of lossy encoding schemes like MP3.

Audio and video content are both important for retrieval: “karaoke” specifies audio content (instrumental version) and video content (animated lyrics). Although YouTube's text search is fairly reliable, many search results do not match the exact query. We introduce an algorithm to classify YouTube videos by category of derivative work.

For example, the FFT of a 16,384 point acquisition acquired at 48 kHz sample rate, the resulting FFT has 8192 bins and each bin has a width of about 2.93 Hz (48,000/16,384). If an FFT spectrum has sufficient resolution, a fractional octave spectrum can be derived from it. Equation (1) describes the gain versus frequency of a 1/b-octave filter ...
