If you're looking to manage audio easily while editing videos, I understand how frustrating it can be when clear instructions aren't available. For those using Banuba Video Editor, the code snippets you've mentioned help set the audio source on both Android and iOS.

However, if you're open to trying another powerful and user-friendly app, Alight Motion might be a great alternative. It not only allows you to add background music but also lets you extract, replace, or edit audio tracks within the same interface, without needing extra tools. It’s perfect for both beginners and advanced users who want quick, all-in-one editing features.

If you're interested in learning how to remove or add audio in Alight Motion step-by-step, you can check out this helpful tutorial. It’s based on hands-on experience and covers everything you need to know.

Thanks!
