Izvinjavam se, biblioteka sa linka je neka mnogo matora, nesto sam pomesao, uglavnom ima dosta takvih biblioteka na primer ova je dosta novija:

https://www.kfrlib.com

DFT/FFT
Convolution
High quality Sample Rate Conversion (SRC)
EBU R 128 Loudness
FIR (Finite Impulse Response) filtering
IIR (Infnite Impulse Response) filtering
FIR filter design using window method
Delay line and fractional delay line
Biquad filters and Biquad cascades
Biquad design functions
Oscillators
Window functions
Waveshaper
Stereo conversion (L/R, M/S)
Goertzel algorithm
DC Remover
Audio file reading/writing
Fast incremental sine/cosine generation
Pseudorandom number generator
Sorting
Mathematical and statistical functions
A-, B- and C- weighting
Template expressions
SIMD functions
Runtime CPU dispatching
All vector lengths are supported
Ring (Circular) buffer

Tu je i fftw biblioteka, ona je jako puno zastupljena i mnogo programa koristi bas tu biblioteku za DSP, mada kazu da je kfrlib skoro duplo brza, to nisam probao, fftw sam koristio u nekim vocoder-ima za sintezu govora od ulaznog texta ...
