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


  • dsputils - utilities and data structures for DSP
  • fft - fast Fourier transform
  • spectral - power spectral density functions (e.g., Pwelch)
  • wav - wav file reader functions
  • window - window functions (e.g., Hamming, Hann, Bartlett)

Installation and Usage

$ go get

package main

import (


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