Intel® IPP provides a wide variety of common audio and general signal processing functions. These functions operate on 1D buffer data and can be grouped as follows:
Low pass, high pass, band-pass filters
Power, root, and logarithmic operations
Statistical functions: min, max, mean, standard deviation and so on
Up/down sampling and windowing
Filtering: FIR, IIR, LMS, convolution, correlation
Linear transforms: FFT, DFT, DCT
Signal generation/initialization: tone, triangular, random, Jaehne, slope, ramp
