Scientific Discussion / Re: ARDFTSRC - Real Discrete Fourier Transform Sample Rate Conversion
Last post by mycroft -ARDFTSRC is using rather extremely trivial algorithm to implement resampling, you just need good FFT lib that supports RDFT transforms (FFTW3, libhpk), and do correct amount of left and right padding and apply pre-constructed taper window to subset of coefficients in frequency domain + do overlap save step.
Construction of the taper window is also very trivial. I might write python script which would do same thing as this filter, if there is enough of interest.
