The term "dual audio" refers to a feature where a video (movie or TV show) is provided with two audio tracks that can be switched between during playback. This is particularly useful for viewers who are not fluent in the primary language of the content or prefer watching movies with an audio track in their native language. In the context of Bolly4u and similar sites, dual audio often implies that a Hollywood movie (or any non-native language content) is provided with an additional audio track in a different language, commonly in Hindi or another widely spoken regional language.
