hz.tools/fftw: hz.tools/sdr/fft bindings for libfftw3
Paul Tagliamonte 2023-02-22 projectThe hz.tools/fftw
package contains bindings to libfftw3
to implement
the hz.tools/sdr/fft.Planner
type to transform between the time and
frequency domain.
The git repo can be found at github.com/hztools/go-fftw, and is importable as hz.tools/fftw.
This is the default throughout most of my codebase, although that default is
only expressed at the “leaf” package – libraries should not be hardcoding the
use of this library in favor of taking an fft.Planner
, unless it’s used as
part of testing. There are a bunch of ways to do an FFT out there, things like
clFFT
or a pure-go FFT implementation could be plugged in depending on what’s
being solved for.
