support mir.fft : thin wrapper around fftw for ND convolution #332

Closed timotheecour closed 8 years ago

timotheecour commented 8 years ago

The goal should be to be as efficient as possible (eg by providing a user friendly wrapper around fftw; note that https://dlang.org/library/std/numeric/fft.html is slow compared to fftw IIRC)

9il commented 8 years ago

Duplicate of #45. Mir will have its own fft with the same spead as fftw (GLAS is fast as OpenBLAS, so I think we can do our fftw analog in D).

p0nce commented 7 years ago

Note that the dplug:dsp package has a FFT that works with real inputs (public domain + boost license). Might be used for 1d convolution only.

timotheecour commented 7 years ago

@ p0nce: well there is already https://dlang.org/phobos/std_numeric.html#.fft but it's much slower than fftw.

@9il: fftw is quite a large library, matching the speed would probably take a lot of effort/time; in the meantime having user friendly wrappers would be nice to have

Agreed (but time constraints)
