The Zoom-In Mic is a feature first introduced on Galaxy Note10 and Note10+, taking video and sound recording to a new level. With the Zoom-In Mic, you can use a pinch gesture on the screen while recording video to zoom in or out, and as you zoom in, the sounds of the subject you zoom in on become louder. Zoom out, and the surrounding sound is no longer suppressed.
To use it, you don't need a separate app. Just open the Camera app to start recording video, pinch to zoom in, and the sound recording will adjust accordingly.
