Sound

Sound on set means the entire audio recording process and the person responsible for it. They select and position the microphones, monitor through headphones whether speech is intelligible and free of unwanted noise, and report when a take needs to be repeated for sound-related reasons. On small productions, the camera operator also takes on this task.

Boom, lavalier microphone, camera audio

You will most often encounter three types of audio recording. A boom is a microphone on a long pole, brought toward the person speaking from above or below without entering the frame. A lavalier microphone is small, attached to clothing or directly to the body, and connected to a transmitter. The microphone on the camera mainly records ambient sound and is rarely sufficient for intelligible dialogue.

Which method is used depends on the scene and the budget. For you, it makes a difference: A boom requires another person in the room, while a lavalier microphone requires contact with your body or clothing.

Who attaches the microphone

A lavalier microphone is often hidden under clothing, secured with tape, and connected to a transmitter attached to the back or hip. The sound person explains beforehand where it should be placed and asks whether they may attach it or whether you would prefer to do it yourself. Both are usual. If being touched feels uncomfortable at that moment, say so; consent also applies to technical procedures. A professional sound person will then show you how to attach it yourself.

Quiet on set

Sound is sensitive. A vibrating phone, rustling paper, or a conversation in the next room—everything ends up in the recording. That is why there is an announcement before every take that silence is required, and why a take is sometimes stopped even though everything in front of the camera was right. This is not your fault. Put your phone on silent before the start and leave it outside the set.

Not every sound has to be right in the original recording. Some sounds are edited or replaced in post-production, or covered with music. Speech that is to be dubbed later is a separate agreement and should be known in advance.

Your voice is identifiable

Sound is the aspect that the fewest people think about when it comes to anonymity. Someone who does not show their face but speaks may still be identifiable to people in their social circle. A voice, a dialect, or a characteristic phrase is often enough. The article Working anonymously explains what can and cannot be done about this.

If you want to shoot anonymously, clarify beforehand whether you are expected to speak, whether the speech will remain in the finished material, or whether it will be altered afterward. This agreement belongs in the contract. If there is a script with dialogue, you should read it with this in mind before agreeing, not only once you are on set.
