X3 has 4 microphones.
The algorithm level has been optimized for wind noise reduction, stereo sound and directional enhancement of sound quality and listening; the focus is on optimizing the human voice and ambient sound in outdoor scenes and sports when in wind noise reduction mode.
X3 has three audio modes: Direction Focus, Wind Noise Reduction, and Stereo. In stereo mode, it is easier to distinguish the left and right channels, which is suitable for use in static scenes. Wind noise reduction mode is suitable for use in outdoor windy environments, such as cycling scenes. Direction Focus is suitable for use in scenes with multiple audio sources. When reframing 360 video, the audio will be enhanced according to the viewing angle.
