<div>Dear Davide,<br clear="all"><br>Unfortunatelly, reading video data (both through mmreader or VideoReader) imports only the visuals, the audio is not read, and thus when saving - you save without sound.<div><br></div>
<div>I'm not sure if there is a convenient workaround (within the realms of matlab) to your problem. Reading sound from video file does not seem to be supported by matlab core functions. However, if you do have Computer Vision System Toolbox - the <span class="yiv829190259Apple-style-span" style="font-size:12px;background-color:rgb(255,255,255);">vision.VideoFileReader </span>object does support this. I'm not sure if saving video with sound is any easier, but at least you can import the sound to matlab.</div>

<br></div><div>So, generally - it's quite complicated (read: "as far as I know - impossible") to load and save with sound with basic matlab functions. Sorry I couldn't help you more.<br><br>Mikolaj<br></div>
