Tips: How to embed WAV audio into FLV videos for background music

So, as you can see, using the right tool makes extracting the audio from videos an easy task. However, what happens if what you wanted to work the other way around? embedding an audio file into a video file. If you are producing a video of your own, this can be very useful, for example to make background sound effects or music. Again, there are online solutions that will help you out with this, as Media Cope, but as seen above, many times, online solutions fall quite short when compared to their desktop counterparts. Luckily, iSkysoft also has the perfect tool to merge audio into video files.

iSkysoft Video Editor for Mac will easily let you set up an audio background for your video project in three easy steps.

1. After installing and running the application for the first time, you need to select the video size format which can be 16:9 or 4:3. After this, you will need to import the video that you want to add the audio into. You can do this by clicking on the File menu, then Import... and browsing your computer for the file. You can also import the files just by dragging them into the Media section of the application.

2. Once the videos are imported (remember you can merge also several videos together), you need to drag them to the lower part of the application, to the Video stream.

3. Now you need to import the audio that you want to use for the background. To do this, repeat step one, but this time browse or drag your audio file, the importing process will start automatically.

4. Just like you did with the video(s), you need to drag the audio files from Media to the bottom of the application, at the Music stream. Here you will be able to cut, move and add effects to the audio as well in a very visual manner, just like video itself.

5. After mixing your audio and video just the way you wanted, all you need to to is to click on the Export button to start the merging and saving process. You will be asked to which format your video should be saved (FLV, AVI, MPEG and many more are available), what will you name it and where you want to save it. You can also find advanced settings below in case you want to adjust them manually, and once you are done tweaking your video, all you need to do is confirm the Export process.

So as you can see, extracting or adding audio to your video files can be as easy as you want. It is all about choosing the right tools to work with, and for that, iSkysoft have the best solutions for you.
