Dear Forum Friends
I discussed Ambisonics with some colleagues and I personally fail to see the awesomeness of recording in this format with special microphones.
Everything you record is baked into a static image. It’s like merging a complex sound ambience and effects into a mono file. Or merging a Photoshop file with many layers into a TIF. Once baked, it’s in there and you cannot edit it properly anymore. You cannot pull out and edit one sound, it’s all together. It’s OK if you have a 360 camera recording and match the sound to this recording. But when you need to do standard tasks, adding dialog, dialog editing, sound effects, constructing ambiances, you’re back to placing mono sounds into a 360 sound design stage that you need to pan correctly and have sound effects follow on-screen actors. If you have CG, you need to construct everything anyway.
I see the benefit of outputting in this format, as you need a vehicle to transport your sound. Here, too, doesn’t Dolby Atmos feature a better system where sounds are like objects and not baked into a static 5.1 image, but they stay separate and can be panned freely in a room. You could have 10 or 100 speakers and it would resolve where a sound is playing from and how loudly, on its own. Ambisonics might be free of licenses? Is that why it’s attractive? So as a transport format Ambisonics might be useful, but for recording?
Also, Ambisonics, as far as I know, is a format from the 60s and 70s. Is there a reason it had no breakthrough (until now, maybe) ?
Maybe somebody has better insight. I’d like to understand.
