Monitor microphone levels and positions so performances sound right.
Sound Editors make sure all audio streams for a recorded production are clear and of high quality. They do this by cleaning up the initial recordings made by a Recording Engineer or Production Sound Mixer, and make them crystalline sounds that burst with vivacity instead of static. Sound Editors work with dialogue, music, and effects. As a Sound Editor, you may decide to specialize, becoming a Dialogue Editor, or Foley Artist.
In this position you comb through the live recordings of a project and select which takes and tapes best suit the project’s aims. You then digitally balance and enhance what you have, and create any electronic effects needed to complete the recordings. If you are working on a visual production, you need to match the recordings to their visual counterpart.
For example if your film begins with a voice speaking over the noise of background traffic, you create the background traffic through combining clips of noise drawn from your sound library, synchronize that noise with the pictures of cars going past, and balance the vocal track with the background noise.
All this requires an ability to memorize large amounts of sound clips and piece them together in many different arrangements. It also requires a keen ear with which you can decipher when a pitch needs to be adjusted.
Your time will be spent in the studio rather than chatting with clients, so be prepared to make friends with your equipment.
