Signal processing
Chapter Signal Processing It includes tools for analyzing and converting signals.
This section describes the calculation of periodograms, filtering, the use of window functions, and linear forecasting, which is suitable for audio signal analysis and processing tasks. High-performance Fourier transforms are described, as well as specialized mathematical transformations, including work with harmonics and Chebyshev polynomials.
It describes working with audio devices in real time. The possibilities of wavelet transformations are available, which is useful for analyzing signals on different time scales.
