The Audio Engineering Technician is responsible for all sound on the job, from making sure the recording is clean and clear, to micing all interview subjects, whether using a boom or lavalier microphones. They normally bring a field mixer, lavs, boom mic and wireless to the project location. Sometimes the Audio Tech records an audio file separately for transcription. If it is a multi-camera, sending audio to all cameras. In some video production projects, there may be more than one Audio Engineer, depending on the complexity and requirements.
