Cinematographer
As a cinematographer, I consider sound requirements during planning. 7.1 mixes need clean takes – avoiding boom shadows, but not forgetting the audio.
Surround sound format with 7 main channels plus subwoofer — the expanded cinema standard with additional surround channels for more precise spatial placement.
What is a 7.1 Mix?
A 7.1 mix is a surround sound format with 7 main speakers plus 1 subwoofer (LFE). Compared to 5.1, 7.1 offers two additional surround channels for more precise spatial placement of sounds.
