Ambisonic vs scratch for the ambience-layer of a 5.1-film?
Hi everyone and happy new year. I’m a newbie and I’d need some tips about “ambience”. I’m currently working on a personal project that’s a narrative film with 5.1 audio. Being mostly self-taught, I tried to figure out which could be a schematic layers-partition for the audio, and I imagine it’s roughly Dialogue, Music, Ambience and SFX (in which I’d include Foley as well). Now, dialogue should be recorded in mono, while music should be usually in stereo. Even foley sounds should be recorded in mono (then pan-placed in post), but my main doubt is ambience… I really don’t know if I’m wrong, but I imagine ambience as a sort of “base” for adding specific foley things, for example: “a walk in a forest” I think could be done with the recording of an actual forest ambience + foley of footsteps on the grass. If it’s true, I think could be useful for me having a basic ambisonic mic like Rode NT-SF1. With Rode I’d capture the ambience “base” in A-format, that through the plugin should easily become a 5.1 ambience “base”. On that base, I’d add the main “narrative” foley efx (like footsteps, or other specific sound-additions).
But perhaps I’m wrong… Perhaps ambisonic things are used mainly for VR or games or documentaries, but not for films! Perhaps in films there isn’t an ambience “base” (too “flat” perhaps, not quite expressive, not controllable enough) rather the entire ambience is an empty canvas to be filled with everything! Everything (both foley AND so many ambience sounds) recorded in mono. So many different ambience sounds for a single scene: trees in the wind, grass, birds, a river far off… All mixed and panned to paint the “ambience picture”. This gives the audio-artist much more control on picture details’ expressiveness and narrative power. If it’s true, an ambisonic mic is not the way to go for my project, a waste of money. Instead I should continue to work with my mono mics.
Could you kindly tell me which is the way commonly the ambience audio “layer” is recorded in most narrative film productions?
Thanks really a lot.
