The best overall solution for surround sound from both the aesthetic and business perspectives is the current one: separate elements are recorded in isolation, usually in mono or stereo, and then the elements are mixed into surround stems using surround panners and separate LFE feeds, while dialog is kept as a mono stem and fed to the center channel (which in a theater is behind the screen).This post may contain affiliate links, which means we may earn a commission if you make a purchase. There are also huge audio engineering challenges with multi-mic setups, such as phase cancellation issues, and how are you going to set it up inside a car or bathroom or other small space? If you have some shots with the "spacial audio" and others without, the difference will be obvious and jarring. Second, you can't control the speaker placement of the final playback speakers, except perhaps in a THX theater, which means that the placement that you carefully recorded will be off when most people watch the movie. Right off the bat, you'd have to set the array up exactly the same way every time for every element that goes into the film or else when you try to mix them all together, it's going to be a huge mess. If you did try to record all the sound elements of a film with multiple unidirectional mics in an array to replicate the speakers of, say, a 5.1 system, you'd quickly run into a huge number of problems. This also enables DVD/digital/streaming releases to have multiple language tracks without having to have entire copies of the whole surround sound mix for each language. That means the dialog can't be completely mixed in with the other elements of the film, instead it is kept as a separate stem. When movies are distributed overseas, generally the dialog is replaced with a dub of the dialog in the language of the destination country. Those other sound tracks that are not dialog are sometimes multi-miked to create a soundscape (an orchestral soundtrack is a very common example), but there's a very good reason why dialog is almost always mixed to a single mono track and then played back over the center channel speaker (or evenly split between left and right or left front and right front when there is no center channel). All other sounds are added later as digitally created effects, music, foley tracks, etc. Generally production sound is meant to capture dialog only as part of the acting. Then, there is the question of whether production sound (meaning the sound recorded while filming) might be recorded using multiple microphones used to create a sense of space, and the answer is that it's unlikely. The effect of a binaural recording only works when listened to with headphones - it doesn't work with any kind of speaker system, so it would be hard to sell a movie to theaters or home viewers that had binaural audio. Binaural recordings use exactly two special microphones that are fitted inside a prosthetic head that is a life size replica of an average human head. Binaural recording is one thing, using multiple microphones to enhance the sense of location is totally different. You've asked two different mutually exclusive questions. So my question is: are there any movies that have been recorded by using multiple microphones to enhance the sense of location? Is this even a worthwhile technique for feature films? Why/why not? Even with many, many speakers such as Dolby Atmos. They just sound a bit bland, to me anyway. This is causing the movie to lack certain immersion. If you're lucky, when two people are talking, they might pan the sound a bit for whoever is talking (slightly lower volume on one side). Mostly, whenever someone is talking in movies, audio comes from the center speaker (5.1 audio system) or is played at the same volume for both speakers (2.0). But here's a randomly picked fragment to let you hear what I mean: The Sound Traveler - Colombia, South America There are a lot of example videos that you can use as reference. ![]() Its the combination of all of theses sound waves is what you actually hear with your ears. Some might even have louder bass because it's traveling through your head to reach the other ear. Some might have a higher or lower pitch when bouncing off metal objects. Sound waves might bounce off from a wall in front or the right of you. Whenever you hear a sound that is, say, coming from the left, you don't just hear the sound in your left ear. Basically a binaural recording is an audio fragment that is recorded as if the device had two ears, simulating human properties.
