I found the solution.

here I am fetching audio files to array

  var songs = [
      '{C:/Projects/audio/public/b(2).mp3}',
      '{C:/Projects/audio/public/b(3).mp3}',
      '{C:/Projects/audio/public/b(4).mp3}'

    ]
     console.log("songs checked")


    //here i am changing path
     var abc = 'C:/Projects/audio/public/sentence after merge.MP3';
    audioconcat(songs)
