When your app shows a video ad while playing music or video with sound, it is not an optimal user experience to mix with different sound sources. This can happen in the following scenario. A user chooses a music file to play from his album in the app. While the music is playing, a video ad in native or interstitial format is presented full screen to the app. The sound of the video ad and the music file will play at the same time. This will result an unpleasant and unexpected experience. To avoid this, you should implement the app following the Audience Network ad audio guide.
