While editing a video sometimes you might want to mix different audio and video clips together.

By doing so you can achieve some interesting results, so today we’re going to show you the best audio & video mixer software.  

What is the best app to merge audio and video files?

Adobe Premiere Pro

Mixing video and audio together in order to create a compilation or a music video is one of the most basic tasks that you can perform with a video editor.

Of course, while any low-end video editor can perform this task, very few manage to blend the two elements together at a truly professional level.

That is where Adobe Premiere Pro is different compared to all the rest, as this timeline-based video editor has all the tools that you may ever need in order to pull off this job.

It doesn’t matter if you want to add a simple sound effect to a 5-minute video, or if you want to make a YouTube-worthy music video, Adobe Premiere Pro has got you covered. Simply annotate along the timeline where you want the secondary audio to be added in, and then let Premiere Pro process the file.

Of course, you can also use the program to perform some minor audio editing as well, so you don’t have to switch back and forth between audio and video editors.

However, that wouldn’t be the case with Premiere Pro anyway, since importing and exporting into Adobe’s dedicated audio editor, Adobe Audition, is incredibly easy.

Here are some of the perks of using Adobe Premiere Pro:

  • Great for mixing video, imagery, and audio together
  • Familiar-looking timeline-based video editor
  • Very compatible with all other Adobe products
  • Works best when paired with Adobe After Effects
  • It can be tested for free for 7 days
