Audio can make users better understand the video image or add a dramatic effect, so usually most of videos that we download from the internet have the original audios. But sometimes, we often record some silent videos. What if we do not like the original audio included in the video that we downloaded from internet and want to replace it with another audio file or what if we want to add the audio we like to our recorded silent video?

The easiest way is to use a tool to add your own audio to the silent video or add a new audio to replace the original audio.
