MJ and Spider-Man leap off the top of a bridge in Spider-Man: No Way Home

I got a Dolby Atmos soundtrack mixing demo at Sony Pictures Studios, and now I know how Spider-Man sounds get made

Film sound manufacturing is a fancy and painstaking course of, requiring a number of groups of people with particular abilities to create and blend the dialogue, music, and sound results that comprise a typical Dolby Atmos film soundtrack.

How do I do know this? I spent two days touring the Sony Photos Studios lot in Culver Metropolis, California the place Sony produces the soundtracks for its movies. The rationale I used to be on the studio was to see the brand new Sony TV lineup for 2024, together with the brand new Sony Dolby Atmos soundbars, however Sony additionally supplied me and different tech writers with a behind-the-scenes take a look at the studio’s manufacturing processes.

Throughout the go to, we had been handled to demonstrations of Foley results, ADR (Automated Dialogue Substitute) and soundtrack mixing. These, together with musical rating composition, are the constructing blocks of soundtrack creation, and when executed effectively, add as much as the detailed and dramatic soundscapes that may be absolutely appreciated when watching films on one of the best Dolby Atmos soundbars and audio system.

A key takeaway from my go to was that film soundtracks comprise solely fragments of “dwell” sound captured through the precise capturing course of. Many of the soundtrack is created fully from scratch within the studio, with dialogue, footsteps, rustling leaves and wind, motor sounds, and explosions added after the actual fact. One other takeaway was {that a} typical soundtrack is comprised of a surprisingly big selection of audio components, all of which in the end get combined right into a seamless complete. I’ll step by way of the varied processes I caught demonstrations of beneath.

Earlier than my Sony Photos Studio tour, I believed most of the sounds you hear in fashionable films had been sourced from a library of digital audio samples. And whereas there’s a few of that happening, the overwhelming majority of sounds are created by a Foley artist.

These sound magicians summon up an array of audio results utilizing plain, on a regular basis objects in extremely inventive methods and preserve an enormous library of mentioned objects to help them in that process. Throughout the demo, Sony Studios Foley artist Gary Hecker carried out the varied sounds that went right into a Western film scene of a band of horses being pushed by way of a forest. Hoofbeat sounds had been created utilizing what regarded like an vintage software pounded on a dirt-covered floor, whereas different objects had been used to generate rustling leaves and jostling spurs. Hecker created the whinnying sounds the horses made when halted together with his personal voice, and the impact was strikingly naturalistic.

After watching the scene’s varied results created one after the other, they had been edited along with sound processing added to make them louder and extra dynamic, and the outcome was an authentic-sounding film motion scene. In one other demo, the sound of Spider-Man capturing webs to leap from constructing to constructing was rapidly created utilizing a whip, and, after a little bit of processing, the impact was convincingly Spider-Man-like.


When an actor indicators on to make a film, a part of the work includes the precise capturing of scenes, however one other equally vital half is overdubbing dialogue later in a course of known as ADR. As with different soundtrack components, a scene’s dialogue is sort of fully re-constructed in a studio to make sure it sounds clear and straightforward to grasp. Whereas no actors had been available for Sony’s ADR demo, we acquired to see a studio the place ADR is edited and listen to examples of dialogue recorded post-shoot being inserted right into a scene.

After all of the sound results creation, ADR, and music scoring work is full, the soundtrack is able to be combined. The massive room – an area with Japanese garden-themed decor – the place Sony’s soundtrack mixing demo befell was one among 14 mixing rooms on the studio, and was a medium-sized mixing room in response to Sony. Even so, it had a complete of 38 audio system for mixing soundtracks in Dolby Atmos. (We had been informed through the demo that each one soundtracks are additionally later combined in a smaller dwelling theater-type area for an Atmos dwelling video launch.)

Utilizing the Spider-Man: No Method Dwelling (2021) soundtrack for the demo, Sony sound mixer Jeff Gross performed the a number of tracks within the combine individually so we may hear them in isolation. The demo additionally alternated between a full soundtrack combine and simply the Dolby Atmos peak results, permitting us to listen to how a lot Atmos results contribute to a soundtrack. Quick model: quite a bit. Coming away from the expertise, I had a renewed appreciation for immersive soundtrack codecs like Dolby Atmos, and of the significance of reproducing Atmos soundtracks adequately at dwelling.

It’s not each day you get to wander round a legendary Hollywood studio and watch individuals at work making films. I could have been there to take a look at the brand new Sony TVs and soundbars, however I additionally acquired to expertise film soundtrack manufacturing, which is a extra magical, intense, and concerned course of than I ever imagined.
