A free app for Android, by palcoder.

Are you fond of editing videos and experimenting with audio that will best suit the scenes? If so, then the Video Replace Mix Remove Audio app is here to help you out!

This tool helps you remove audio from or video or replace it with something you prefer. These changes can be made for the entire video or just for selected clips. This does not hinder you from using the original sound and mixing it with a different one. 

The app was built with a clean and simple user interface so you can just focus on editing your output without any hassle or distractions.
