Spatial Audio for 4 BLOCKS – Amazon Prime 360 (like THX Trailer)

Introduction to Spatial Audio

In the ever-evolving world of audio technology, spatial audio stands out as a groundbreaking innovation. This advanced audio technology allows listeners to experience sound in a three-dimensional space, creating an immersive and realistic audio environment.

Whether you’re watching a movie, playing a video game, or listening to music, spatial audio enhances the overall experience by making you feel like you’re right in the middle of the action.

Understanding the Basics: What is Spatial Audio?

Spatial audio is a revolutionary technology that simulates the way sound behaves in the real world. Unlike traditional audio formats that deliver sound from a limited number of directions, spatial audio allows listeners to pinpoint the source of sounds in a three-dimensional space.

This is achieved through the use of multiple audio channels, advanced signal processing, and clever audio engineering.

Imagine watching a movie where the sound of footsteps comes from behind you, a car zooms past from the left, and a helicopter hovers above. Spatial audio makes this possible by creating a realistic soundscape that mirrors real-life audio experiences.

By accurately simulating the direction and distance of sounds, spatial audio provides a level of immersion that traditional audio formats simply cannot match.

The Significance of Spatial Audio in Modern Media

In today’s media landscape, spatial audio has become an essential component of the viewing and listening experience. In movie theaters, spatial audio allows audiences to feel like they are part of the action, with sounds coming from all directions. This creates a more engaging and immersive environment, enhancing the overall cinematic experience.

For home theater enthusiasts, spatial audio brings the magic of the movie theater into the comfort of their own homes. With the right setup, viewers can enjoy a truly immersive audio experience that rivals that of a professional movie theater.

Spatial audio is also a key feature in virtual reality (VR) and augmented reality (AR) applications, where it plays a crucial role in creating realistic and immersive environments.

How ‘4 Blocks’ conquers the YouTube world with a 360° trailer:

The new series “4 Blocks” is airing on TNT and has been given a very special experience for its promo – a 360° video packaged as a unique 360° trailer. The THX logo, often associated with high-quality audio experiences, enhances the immersive nature of the ‘4 Blocks’ trailer.

But what’s behind the audio backdrop that makes this immersive experience possible?

An exclusive insight into the innovative audio production behind the scenes

For this clip, I took over the mixing to turn an already finished version for Facebook into a working version for YouTube. The arrangement of speakers plays a crucial role in delivering the immersive audio experience for the ‘4 Blocks’ trailer.

The background to this is that YouTube does not support an additional stereo track compared to Facebook and uses 4 instead of 8 channels for the 360° sound – but I have the right workaround for this.

The challenge: building a bridge between Facebook and YouTube

For this clip, I took over the mixing to turn an already finished version for Facebook into a working version for YouTube. The challenge? In contrast to Facebook, YouTube did not support an additional stereo track at the time and used 4 instead of 8 channels for the 360° sound. A problem that required a creative solution.

My personal workaround: head-locked stereo track

I found the solution in a workaround that focussed on a head-locked stereo track, which is mandatory on Facebook. Similar to the Apple Vision Pro approach, I combined audio objects with an Ambience bed, such as Ambisonics, and added a non-diegetic head-locked stereo track for background music or voice-overs.

THX trailers have set the benchmark for audio quality, influencing the techniques used in the ‘4 Blocks’ trailer.

This method made it possible to retain the original immersive character of the audio experience while adapting it to the technical limitations of YouTube. Technologies like Dolby Atmos and THX Audio are not suitable for this.

I work with my own workaround in converting head-locked stereo to head-tracked audio. Here, you can find more info on the Realitykit Pro.

The Evolution of Audio Technology

The journey of audio technology from its humble beginnings to the cutting-edge advancements of today is nothing short of remarkable. Let’s take a brief look at how audio technology has evolved over the years.

From Mono to Spatial: A Brief History

In the early 20th century, monaural (mono) sound was the standard, with audio signals transmitted through a single channel. This provided a limited and flat audio experience. The introduction of stereophonic (stereo) sound in the 1950s marked a significant improvement, with two channels providing a wider and more dynamic soundstage.

The 1970s saw the advent of surround sound, which used multiple channels to create a more immersive audio experience. This was a game-changer for movie theaters and home theaters alike, allowing audiences to feel like they were surrounded by sound.

The 1990s brought digital audio to the forefront, with formats like Dolby Digital and DTS offering superior sound quality and greater flexibility.

Today, spatial audio represents the pinnacle of audio technology. With innovations like THX Spatial Audio and Dolby Atmos, listeners can experience unprecedented levels of immersion and realism.

These technologies use advanced signal processing and multiple audio channels to create a three-dimensional soundscape that mirrors real-life audio experiences.

In conclusion, the evolution of audio technology has been driven by a desire to create more immersive and realistic audio experiences. From mono sound to spatial audio, each advancement has brought us closer to achieving this goal. As we continue to push the boundaries of what is possible, the future of audio technology looks brighter than ever.

The importance of immersive 3D audio

The importance of surround sound to the 360° video experience cannot be overstated. The THX Deep Note, famously associated with the Star Wars franchise, exemplifies the importance of high-quality immersive audio. It allows us to immerse ourselves in the scene by providing a spatial feeling that enhances the visual impression.

By customizing the audio for YouTube, we were able to ensure that viewers could immerse themselves in the world of “4 Blocks” regardless of the platform.

Conclusion: A bridge between technology and creativity

Working on the 360° trailer for “4 Blocks” was not only a technical challenge, but also a creative one. It was an opportunity to push the boundaries of what is possible in audio production for visual media while ensuring that the audience, regardless of platform, has the best possible experience.

Innovative techniques in audio production: beyond Dolby Atmos and THX

While Dolby Atmos and THX are well-known in audio production for cinematic experiences, specialised projects such as the “4 Blocks” trailer require customised approaches. A fan-made trailer by Paul S. Gordon showcases innovative audio and visual techniques, similar to those used in the ‘4 Blocks’ trailer.

My work illustrates how bespoke audio customisation is critical to overcoming platform limitations while ensuring a deeply immersive experience.

The role of 3D audio in today’s media landscape

3D audio, a key component of immersive experiences, is playing an increasingly important role in media production. It’s not just about improving sound quality, but more about giving listeners a sense of presence and immersion.

This aspect is particularly relevant for storytelling in films and series, as it intensifies the emotional impact and connection with the audience.

The need for expertise in immersive audio production

The “4 Blocks” trailer is an example of how essential expert knowledge is in immersive audio production. Many production companies face challenges that cannot be overcome without specialised knowledge and experience.

My approach shows how important it is to work with professionals who not only understand the technical hurdles, but can also develop creative solutions to create the best possible audio experience.

A call for collaboration: Why the right partner matters

I encourage production companies and creatives to partner with experts in immersive audio from the very beginning of their projects. Considering audiovisual strategy early on can not only save time and resources, but also elevate the final product to a new level. Let’s push boundaries together and create unforgettable experiences.
