Recording engineers operate and maintain video and sound recording equipment, including sound effects machines. Field technicians set up and use portable broadcasting equipment. In the motion picture industry, broadcast technicians are called sound mixers or re-recording mixers. They produce movie sound tracks.

As scenes change, they fade sounds in and out as well as change their volume. At the same time, mixers follow directions written on the script. Technicians work on specific sounds. Eventually, they blend all the sounds together. Broadcast Technicians is in the Engineering, Science, and Technologies Career Cluster.
