What you need to know about boompole usage and best practices

In an earlier blog post, we established that one of the golden rules of audio recording is achieving a good signal-to-noise ratio, and that one of the best methods for doing this is to position the microphone as close to the sound source as possible.

Camera-mounted microphones may be great for busy run-and-gun situations, but when critical dialogue is involved, they just simply cannot get close enough for a lot of applications.

This is where boompoles come into play.

Though a number of factors may influence the limitations on mic placement potential, the overall preferred method is to boom from above, or below if absolutely necessary.

Best boom positioning

Booms are a commonly used piece of sound equipment that allow you to position the mic close to your subject while staying just out of shot. Though a number of factors may influence the limitations on mic placement potential (for example, the chosen camera frame and the overall design of the set), the overall preferred method is to boom from above, or below if absolutely necessary. You should never record from the sides.

Holding the boom pole above shot ensures that the optimum pickup area of the mic is directed towards the subject's mouth, and then towards the ground – which we assume won't be generating much noise. This will give you natural-sounding dialogue, which is well-isolated from the ambience of the surroundings. In addition, the boom and mic will both be well out of the actor's way, leaving them free to roam the scene and not feel distracted by the sight of it.
