go-dsp is a digital signal processing package for the Go programming language.

• fft - fast Fourier transform
  • fft.FFT([]complex128) []complex128 - forward FFT for complex inputs
  • fft.IFFT([]complex128) []complex128 - inverse FFT for complex inputs
  • fft.FFT_real([]float64) []complex128 - forward FFT for real inputs
  • fft.IFFT_real([]float64) []complex128 - inverse FFT for real inputs

$ goinstall "github.com/mjibson/go-dsp/fft"

package main

import "github.com/mjibson/go-dsp/fft"
import "fmt"

func main() {
        fmt.Println(fft.FFT_real([]float64 {1, 2, 3}))
}

• All FFT functions:
  • use goroutines
