Monitor microphone levels and positions so performances sound right.
A Re-Recording Mixer works with all of the sounds that go into a movie and “mixes” them to create the final soundtrack. Audiences should never think that the music is too loud, or the Actors ’ voices are too low – unless of course it’s a conscious stylistic choice. Because as the Re-Recording Mixer, its your job to create the perfect mix of levels and volumes.
Creating this perfect mix takes practice, and a bit of finesse, as you take all of the pieces (dialogue, sound effects, music, background noises…) and put them together to make a cohesive and fluid sound.
Your work as a Re-Recording Mixer takes place during the post-production phase of movie-making (film being your primary medium, though some TV dramas require Re-Recording Mixers too). Your budget and time available to complete the assignment won’t be very generous, so you should be able to work well under pressure—getting it all done fast will be the biggest requirement. In fact, movie turn-around times are so short that you also have to make a quickie pseudo-soundtrack for audience previews while you work on the final version.
