HSoxLib

Haskell bindings to LibSoX, the Swiss Army knife of sound processing programs.

Tested on debian bullseye with libsox 14.4.2 and gcc 9.2.1 installed via apt.

Warning: this library is unofficially and still in development.

Quick start

Make sure you already have the c library installed, for debian user, you can simply install it by:

apt-get install libsox-dev

Check version number of libsox you have:

(the version should no less than 14.4.0)

>>> import Sound.HSoxLib
>>> soxVersion
"14.4.2"

Getting audio file's information

import qualified Sound.HSoxLib       as Sox
import qualified Sound.HSoxLib.Types as T

data AudioTrack =
  AudioTrack { artist         :: Maybe String
             , album          :: Maybe String
             , sampleRate     :: Maybe Double
             , sampleEncoding :: T.SoxEncoding
             } deriving Show

audioTrackGetter :: Sox.AudioTrackGetter AudioTrack
audioTrackGetter =
  AudioTrack <$> Sox.artistGetter
             <*> Sox.albumGetter
             <*> Sox.sampleRateGetter
             <*> Sox.encodingGetter

getAudioTrack :: IO AudioTrack
getAudioTrack =
  let filepath = "/home/un/Music/test.flac"
   in Sox.simpleSoxOpenRead filepath $ Sox.runGetter audioTrackGetter

main :: IO ()
main = Sox.withSox $ do
  audioTrack <- getAudioTrack
  print audioTrack
