A camera microphone is an important accessory for a video recording. You can improve the sound quality of your videos with this. An external microphone has a wider frequency range, a higher directional sensitivity and often more possibilities than a built-in microphone. The different microphones are often also especially suitable for a usage situation or environment. This depends on the type of microphone. You can record isolated sounds from afar with a shotgun microphone, for example. A stereo microphone is more suitable to record the ambiance of a space.
