A dual audio movie is a specially encoded video file which has more than one audio languages. Modern Blu-ray movie discs are now coming with multiple audio languages support. So, you don't need to buy the same movie again if you want to watch it in some other language. Media players, DVD, and BD players provide an option to select the desired audio language with 5.1 or 7.1 Dolby digital surround sound.
Older media players may or may not support dual audio movies. However, they play the movie with the default language only without giving an option to change the audio track. Dual audio movies perform well also on android smartphones and iOS devices. The only thing you need is a compatible video player app. Most of the time it may happen that you do not need the multiple audio languages and just want to convert the movie to a single audio. This is the case when you try to convert movies or videos for your android or iOS devices.
However, there is actually no need to convert a dual audio movie to single audio because you can still convert any dual audio movie for your smartphone, tablet or iOS devices while preserving all the audio languages. In this tutorial, we will teach you how you can convert any dual audio movie to a single audio of your choice.
