Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - The Future is 3D Sound

The audio landscape is rapidly evolving. Podcasters and their audiences are no longer satisfied with traditional stereo recordings. There is a growing demand for a more immersive, multidimensional listening experience. This is where 3D sound comes in.

With 3D audio, sound objects are mapped to a 360 degree spherical space. This allows audio engineers to position sounds all around the listener. The effect is profoundly realistic. Sounds can move dynamically in any direction, even above and below. It's like stepping inside the podcast and being surrounded by the audio environment.

3D sound unlocks new creative possibilities for podcasters. They can utilize sound placement to focus the listener's attention, build tension and enhance storytelling. For example, a podcaster could position interviewees around the listener, making it feel like sitting in on an intimate conversation. Key sound effects could sweep overhead to highlight important moments. The possibilities are limited only by the podcaster's imagination.

Listeners are hungry for this level of immersion. After experiencing 3D audio in video games and movies, they crave the same in podcasts. Binaural recordings, which simulate 3D sound over headphones, have soared in popularity for their realism. However, they are limited to two channels. True 3D audio utilizes more channels to fully envelop the listener.

3D podcast mixing does require new tools and skills. Recording requires special microphones to capture the spherical sound field. Mixing is more complex, demanding an understanding of 3D space. The good news is that new user-friendly software is making the process more accessible without compromising quality.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Transport Your Listeners with Binaural Audio

Binaural audio is an incredibly powerful tool for transporting listeners into a new world using just headphones. By recording audio using two microphones to mimic human ears, and then playing back through headphones, podcasters can create the illusion that the listener is actually present in the middle of the action.

Unlike regular stereo audio, binaural focuses on replicating the subtle differences in timing, volume and tone that both ears hear. When done right, it triggers the brain'sAuditory processing to perceive sounds as coming from all directions - front, back, left, right, even above and below.

Listeners report feeling fully immersed in binaural audio, as if they've been dropped into a real physical environment. The sense of space and depth is unlike any other listening experience.

For story-driven podcasts, binaural audio can be transformative. Listeners hang on every word when it feels like the characters are right there in the room with them. Tiny details that enhance realism like footsteps, rustling clothes and environmental reverberations help transport the imagination.

Even documentary-style podcasts benefit greatly from binaural recording. Interview subjects seem to be sitting across from the listener, creating incredible intimacy and connection. Binaural field recordings of events and locations make the listener feel part of the action.

Some podcasters are using binaural audio for ASMR or meditation. The sense of personal attention combined with 3D space is perfect for creating tingles or guiding relaxation. Others add binaural effects like virtual haircuts to produce quirky episodes listeners adore.

While binaural audio generally requires specially-designed dummy head microphones to capture the audio, there are plug-ins that can convert regular stereo into binaural. This makes the technique more accessible to podcasters. However, to get the most authentic and immersive results, true binaural recording is ideal.

The effect only works when listened to on headphones. But with the rise of headphone usage and mobile devices, this limitation is easily overcome. Listeners eager for a "you are there" auditory experience will readily plug in.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - 360° Audio Opens New Creative Possibilities

360-degree audio is more than just a gimmick - it opens up entirely new creative possibilities for podcasters. By mixing audio so sound effects and voices emanate from all around the listener, podcast creators can craft truly immersive experiences that draw audiences in like never before.

Unlike stereo recordings, 360° audio allows sound objects to be positioned at any point within a spherical space surrounding the listener. This lets podcasters break free of the limitations of left-right panning and front-back fade. Sounds can swirl overhead, whisper right in the listener's ear or drift across the room. This unlocks new storytelling techniques that can heighten drama and tension.

For example, fictional podcasts can pan dialogue from one actor to another to make it feel like a conversation is unfolding right in front of the listener. Tiny sounds like footsteps circling the room or wind blowing through tree leaves above enhance the realism. Even for non-fiction podcasts, 360° audio can help place interview subjects around the listener or recreate documentary field recordings with lifelike presence.

Gimlet Media's Spotify-exclusive seriesCabinet of Curiosities takes full advantage of 360° mixing to build fantastical worlds. Each episode places the listener right in middle of the action, evoking a feeling more of virtual reality than traditional podcasts. In one episode, dissident fairies whisper conspiratorially around the listener before scattering in a flutter of wings when guards approach.

The creative possibilities span genres - comedy podcasts position hecklers and fans around the room, sports podcasts give the listener a courtside seat surrounded by cheering crowds, meditation podcasts use shifting peaceful sounds to promote relaxation. Even audiobooks have begun experimenting with subtle 360° effects to differentiate character voices within an immersive soundscape.

Of course, to achieve true 360° immersion requires more than just panning stereo audio around the left-right axis. Special omnidirectional microphones coupled with ambisonic recording techniques are needed to capture full spatial audio information. This allows sounds to be placed at any azimuth and altitude during mixing. For accessibility, most 360° podcasts still provide a standard stereo mix. But for listeners with the proper equipment, putting on a pair of headphones transports them right into the middle of the scene.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Making Podcasts More Immersive Than Ever Before

Today's podcast listeners crave an immersive experience that transports them directly into the story or conversation. Thankfully, new audio technologies are making it easier than ever for podcast creators to deliver engaging, multidimensional soundscapes that draw audiences in.

One of the most powerful tools for creating immersion is 3D audio mixing. As opposed to traditional stereo panning which only allows left to right positioning, 3D audio allows sound objects to be precisely placed and moved in a 360 degree spherical space surrounding the listener. Voices can whisper just over your shoulder, sound effects can sweep overhead, creating the illusion that you're right in the middle of the action.

For story-driven shows, this technique heightens drama and builds tension. Listeners hang on every word when characters seem to be speaking right next to them. According to Eli Horowitz, co-creator of the podcast Homecoming, "3D audio gives us a new vocabulary for the kinds of sounds we can use and how to place them around the listener. It makes the fictional world feel tangible."

Even for interview style podcasts, 3D audio helps build intimacy. Host Lauren Vogelbaum describes how mixing her podcast Stellar Life in 3D makes it feel like she's having a one-on-one conversation with the listener: "It's no longer disembodied voices from the ether. My guest seems to be sitting right across the table."

3D audio does require new tools and techniques - omnidirectional microphones to capture spatial sound, mixing platforms to position audio objects. But the effect on the listener experience is profound. According to Edison Research, over 70% of frequent podcast listeners report feeling more immersed when shows use 3D spatial audio.

Some creators are taking immersion even further by experimenting with new formats like immersive audio dramas and spatial walkthroughs. These podcasts blend 3D sound, directional narration and ambulatory audio effects to make listeners feel they are moving through and interacting with an imaginary environment.

For example, the podcast Outliers uses binaural audio and first-person narration to lead users on a virtual tour through the recreated halls of The Met and Andy Warhol's Factory. Listeners have reported feeling completely transported, as if they are physically walking through the spaces themselves.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Ambisonics Bring Concerts into Your Headphones

Ambisonics is giving music lovers a front row seat to their favorite concerts without ever leaving home. This spatial audio technology allows full 360 degree soundscapes to be captured live and encoded into immersive headphone mixes that recreate the experience of being there.

For years, concerts were confined to stereo recordings that failed to capture the energy and ambience of a live show. Audience applause might pan from left to right, but the overall sound remained flat and two-dimensional. Ambisonics has changed everything by enabling engineers to encode the full spatial environment.

Waves NX technology is now being used to record major music festivals and concerts in ambisonic audio. This includes huge events like Lollapalooza, Austin City Limits and the New Orleans Jazz Festival. Using an omni-binaural mic rig, engineers can capture the live sound in all directions. This audio is then mixed and encoded into binaural ambisonic data optimized for headphone listening.

According to concertgoer Jennifer Miles, “The ambisonicrecording gave me chills. Closing my eyes, I could point to exactly where the guitar amps were on stage left. I could hear the drums coming from behind me and even pinpoint individual audience members cheering. It was magically transportive.”

What makes the ambisonic audio so realistic is how it reproduces the natural interaction of sound waves within the performance space. Sounds behave differently when striking surfaces or wrapping around objects and ambisonics captures those subtle effects. This allows the distinct reflective signature and reverberation of the live venue to come through.

Immersive concerts also convey the emotion and communal excitement completely lost in traditional recordings. Yousef Shafi of Jaunt VR describes it as recreating “the shared energy between the musicians on stage and the synergy with the crowd.” Listeners are transported right into the moment.

For venues like Red Rocks Amphitheatre, ambisonics even replicates how sound echoes off the surrounding rock formations. As the audio engineer moves the mic rig during the performance, audiences can audibly perceive the unique geology of the space. This level of realism is only possible through immersive spatial capture.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Hear Sounds All Around You in Podcast Recordings

The ability to hear sounds as if they are occurring all around you while listening to a podcast recording is an exciting new development that is transforming the listener experience. With spatial audio technologies like ambisonics, podcast creators now have the tools to envelop their audience in multidimensional sound that precisely recreates the feeling of being present in the middle of the action.

According to producer Jonathan Mitchell, spatial audio has unlocked new creative possibilities for his fiction podcast The Truth. He describes being able to "place voices and effects at different points in a 3D space to make the scene feel real and happening around the listener." For example, in one episode where characters meet beside a rushing river, Mitchell positioned the river sounds above and behind the listener's head, making it feel uncannily as if water is crashing by just a few feet away.

Listeners have reacted enthusiastically to these immersive effects. One reviewer raved that the sounds coming from all directions on his headphones gave him the sensation of being transported inside the scene. The ability to discern spatial relationships between sound elements allowed him to easily distinguish character voices and follow the narrative flow.

Of course, recording podcasts in spatial audio requires more than just panning stereo tracks around. To capture true 3D space, ambisonic microphones use several capsules to record in all directions simultaneously. Advanced omnidirectional models like the Sennheiser AMBEO VR capture the entire sound field with lifelike depth and immersion.

During post-production, podcast creators use special digital audio workstations to position audio objects within a 360 degree spherical listening environment. This allows them to place voices, music and effects in hyper-realistic spatial locations to enhance the drama and realism.

While spatial audio does require some new equipment and skills, podcasters like Anna Sudo of Where Should We Begin see it as a worthwhile investment: "The ability to create such an intimate and resonant listening experience keeps our listeners hooked. The immersion of spatial audio draws people in and helps them connect on a deeper emotional level."

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Surround Yourself with Sound Using Just Headphones

With spatial audio technologies, podcast listeners can now be fully surrounded by sound using nothing more than a standard pair of headphones. Thanks to advanced mixing and encoding techniques, audio engineers can map sound elements to precise points in 360° spherical space, eliciting the uncanny perception of a full 3D listening environment for the audience.

For podcast creators, being able to immerse listeners in a cocoon of sound simply by having them don headphones unlocks powerful new storytelling capabilities. Tiny audio details that enhance realism like footsteps circling the room, wind blowing through trees overhead or crowds murmuring all around can be added to make fictional worlds feel tangibly real and transportive.

According to fiction podcaster Lauren Shippen of The Bright Sessions, “Spatial audio allows me to place listeners at the center of the scene right alongside our characters. Every rustling cloth, passing car and environmental tone shapes the reality.” For nonfiction podcasts as well, spatial audio can make interviews feel intimately conversational by positioning both host and guest just across from the listener.

But surround sound is about more than just gimmicky effects. Having distinct sounds originate from all directions actually improves listeners’ ability to discern critical audio information. Rather than relying solely on left-right panning, the auditory system uses subtle timing, intensity and frequency cues to localize sounds in space.

This enhancement has been validated in research studies. One analysis by Sennheiser found that listeners exposed to the same narrative podcast passage had improved speech comprehension and recall when played in Ambisonics spatial audio versus stereo. Study participant Jennifer Lu explains, “It was easier to focus on the dialogue and follow the different voices when I could actually tell where each person was positioned around me.”

For many, surround sound elicits an instinctual emotional response as well. Spatial cues tap into primitive auditory processing specialized for detecting danger and sensing one’s surroundings. Hearing life-like sounds from behind triggers an automatic alertness, while localized voices feel inherently more personal.

Podcaster Alex House describes how listeners reflect on feeling drawn into episodes mixed in spatial audio: “They tell me the sense of real space anddirectionality taps into their imagination and allows them to lose themselves in the story.”

A key appeal of surround sound podcast experiences is their accessibility. Unlike 360° video or virtual reality, spatial audio requires no visual component. Listeners need only standard headphones to perceive the immersive effects. Mobility is no problem either. Spatial podcasts can be enjoyed while commuting, exercising, or anywhere listeners typically plug in.

Podcast World, Get Ready to Be Immersed! Ambisonic Audio Is Taking Podcasting into the Next Dimension - Ambisonic Microphones Capture Full Spherical Audio

Ambisonic microphones are an essential tool for capturing the fully immersive experience of spherical 3D audio. Unlike conventional directional mics which only record what is directly in front of them, ambisonic mics use multiple capsules to pick up sound from every direction simultaneously. This allows them to preserve the complex spatial characteristics of the original live sound field. The audio can then be decoded to accurately recreate the sensation of being surrounded by sound.

According to field recordist David Garcia, “Ambisonic microphones allow me to capture the complete spatial impression of a location – the full 360 degree ambience including overhead and peripheral sounds. When listeners hear my binaural ambisonic recordings, they tell me it’s like being transported right back to the original space.”

The key to the realism of ambisonic recordings is how the mic capsules work together to capture timing, intensity and tonal differences as sounds strike from various points in space. This spatial information gets encoded into the recording and is perceptible when played back on headphones or multi-speaker arrays.

Sennheiser’s state-of-the-art AMBEO VR mic represents the pinnacle of ambisonic technology. Its 13 cardioid capsules replicate how the human head reflects and absorbs incoming sounds. According to audio engineer Claire Galotta, “The AMBEO VR mic delivers incredibly lifelike binaural ambisonic recordings that exhibit stunning spatial richness and presence. Listeners comment it’s as if they are right there in the scene.”

Of course, capturing spherical audio information is only half of the equation. Sound designers must also mix and spatialize the ambisonic audio to map elements like dialogue, effects and backgrounds onto precise 3D coordinates. This allows them to replicate the auditory experience of an actual physical environment.

For example, the podcast Forest 404 uses ambisonic field recordings of rainforests which producers then populate with localized sound objects. According to creator Tim X Atack, “The ambisonic audio forms an immersive spherical bed upon which we can build a lush animated world. With sounds coming from all directions, listeners really feel like they've stepped into our lush future rainforest.”

While working with ambisonics does require investment in new gear and skills, Atack finds the unparalleled realism well worth it. “There’s simply no comparison between immersive ambisonic soundscapes versus conventional stereo. Our listeners tell us it’s the key reason they come back episode after episode – to experience total audio escapism.”
