Lavalier microphones have become the standard for filming people talking in controlled environments, whether that be during news reports or talk shows. They come with many benefits because they can be clipped close to the speaker, and since they're stationary, they are able to keep balanced audio levels. An important aspect of lavalier mics are where to place them, because you don't want them to be too obvious, but you also don't want to sacrifice good sound for placement. A general rule of thumb is to clip a lavalier between the top two buttons on a shirt, which is roughly about eight inches below the mouth. They come in both wired and wireless varieties, and although wireless allows for more movement, it gets a little more complicated because of variating frequencies. I have a question about how the microphones are powered and whether they're connected to something that runs on batteries, and if so, how often do you have to change the batteries?
