Video Reader and Audio

I am using the below code to merge multiple videos together. Is it possible to save the audio from one of the videos to the merged (new) video?

vid1 = VideoReader(LeftVideo,'CurrentTime',TimeOffset_L);%Left
vid2 = VideoReader(RightVideo,'CurrentTime',TimeOffset_R);%Right

videoPlayer = vision.VideoPlayer;
outputVideo = VideoWriter(OutPutVideo);
outputVideo.FrameRate = vid1.FrameRate;
open(outputVideo);

for i=1:60 
    img1 = readFrame(vid1);
    img2 = readFrame(vid2);

      imgt=[img1 img2];
      step(videoPlayer, imgt);%play video
      writeVideo(outputVideo, imgt); %record new video
  end

release(videoPlayer);
close(outputVideo);

You need vision.VideoFileWriter
