Bring Your Audio to Life: How to Evoke Emotion with Sound Design - The Power of the Human Voice

The human voice is an incredibly powerful instrument. Unlike music and other sounds, the voice has the ability to convey complex emotions and instantly connect with listeners. This makes it an invaluable tool for storytellers in any medium, but especially for audiobooks and podcasts where the voice carries the narrative.

Experienced narrators understand the power of their vocal instrument. As audiobook narrator Scott Brick says, "My responsibility is to be the conduit between the author and the listener. I'm the storyteller, and I have to convey with my voice the intent the author had when writing the words on the page." Brick modulates his voice to fully inhabit each character, making them distinct and memorable.

The right vocal performance can create an intimate bond between narrator and listener. According to clinical psychologist Dr. Wendy Mogel, "Audiobook narrators with pleasant, modulated voices feel like friends; we welcome them into our homes and heads." She explains that because humans are "hardwired" to respond to voices, a narrator's emotional nuance and vocal range imprints the story effectively.

Directing voice talent is crucial to elicit authentic and compelling performances. Eli Horowitz, co-creator of the narrative fiction podcast Homecoming, says "If we're doing our jobs right, we're creating an environment where the actors can do their best work." This requires establishing an open, collaborative dynamic where actors feel empowered to take risks and make creative choices.

According to sound engineer Dann Michael Thompson, dynamic vocal performances grab attention. “A trained actor has a wider palette of expression that helps suspend disbelief. The audience hangs on each rise and fall—when the voice cracks in anguish or drops to a whisper, you achieve a captivating intimacy.” This emotional resonance keeps the audience engaged.

Casting the perfect narrator for your audiobook or podcast is arguably the most important creative decision you'll make. The right vocal talent can transport listeners into your storyworld, while a less-than-ideal match can distance them. Audiobook narrator Scott Brick believes you must cast for proper interpretation, not just acting chops. “You need someone who intuits the characters...who understands the author’s intent."

When choosing talent, consider the genre and target demographic. According to Michele Cobb, executive director of the Audio Publishers Association, “Different genres have different needs. For romance and mysteries you want a smooth, conversational tone. Thrillers and adventures warrant more intense, dramatic reads." Know your audience—if your book is for younger listeners, find talent whose vocal quality will resonate. For general audiences, choose versatile, expressive narrators.

Ideally, you’ll hear the characters’ voices clearly in your mind as you write. Seattle-based author Maria Semple says, “The whole time I was writing ‘Where’d You Go, Bernadette,’ I was channeling the voices in my head.” She selected narrator Kathleen Wilhoite because her voice perfectly matched the one Semple imagined for her endearingly eccentric heroine.

While big names like Stephen King and Michelle Obama choose A-list actors to narrate their audiobooks, unknown voices can also enthrall. The breakout success of Andy Weir’s “The Martian” was partly thanks to narrator R.C. Bray, an actor new to audiobooks. Bray's emotional, high-energy performance transported listeners and turned the audiobook into a phenomenon.

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Directing Actors for Maximum Impact

Directing voice actors is a nuanced art that requires eliciting authentic, compelling performances that maximally impact listeners. Unlike film directors who can utilize visuals, audiobook directors must rely solely on vocal performances to establish characters, settings, and tone. Through thoughtful direction, they empower actors to inhabit each role fully and transport the audience into the storyworld.

According to Pete Simon, director of fiction podcasts at Audible, “You have to set the stage so [actors] can do their best work. Explain the context and background so they understand the world and characters.” Providing immersive direction documents helps actors embody roles organically. Simon says, “I want [actors] to feel they have the confidence to bring themselves into the performance and not feel restricted by my direction.”

Establishing trust and open communication is key. Eli Horowitz, co-creator of the narrative fiction podcast Homecoming, says “We spend time getting to know [actors] as people first. We want our relationship to be a collaboration.” He gets feedback from actors on scripts and direction, creating space for creative risk-taking.

To capture authentic vocal performances, directors must cultivate the right emotional headspace. Audio director Dann Michael Thompson advises, “During emotional or terrifying scenes, I lower the lights and play ominous music to help actors get into that headspace.” Sound effects, music, and environmental cues evoke mood and inform performances.

Thompson also tailors direction to each actor’s process, saying, “Some actors want to dive right in, others need more preparation. I adjust my style - some need continual feedback, others want the freedom to explore.” Directors must adapt their approach to connect fully with each actor.

According to casting director Khari Streeter, specific and concise direction gets the best results. “Vague, abstract language can sometimes lose actors. Be concrete and descriptive about character motivation and emotional state.” For example, words like “urgently” or “sheepishly” provide clearer direction.

Since much audiobook direction happens remotely, directors keep takes focused. As Simon explains, “We make sure actors stay close to the mic so we can edit takes together seamlessly.” He also avoids over-directing, which can flatten performances. Letting actors follow their instincts yields rich results.

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Sound Effects That Transport Listeners

Sound effects possess the uncanny power to instantly transport listeners into vivid imagined worlds. Unlike music, sound effects create concrete associations that root the audience in tangible settings and scenarios. According to Pete Simon, Audible’s director of original programming, “Sound effects trick the brain - you hear a crackling campfire or screeching tires, and suddenly you’re there.” He explains that while music sets emotional tone, sound effects provide specificity that makes fictional worlds believable.

Masterful sound designers leverage this transportive power of audio illusions to fully immerse audiences. For the podcast Limetown, composer Elyse Willis created hundreds of retro-styled sound effects to conjure the mysterious town. “Every scene was underscored by rich textures of typewriters, dial phones, record players. The sounds place listeners in that intimate space,” she explains. Foley artist Shaun Brennan records custom sounds on set to embed listeners in the visual world. For the horror podcast The Left Right Game, he used mallets on watermelons to simulate the bone crunching sounds of the narrator’s hand injuries, making the violence visceral.

According to Ryan Billia, sound designer for Marvel podcasts, sound effects establish physical and emotional realism crucial for suspension of disbelief. “For Wolverine, I added metal scraping sounds when his claws come out. It tells the story while conveying his animalistic nature,” he explains. Billia also builds intricate ambient backgrounds that create an immersive sense of place, whether it’s the humid bayou in the podcast Black Widow: Bad Blood or the streets of Krakoa in X of Swords.

Some shows forgo conventional sound design in favor of binaural or ambisonic audio captured on special microphones. Shows like Passenger List and The Truth use these microphone techniques to create 3D audio landscapes that literally surround the listener. The effect can feel jarringly real, as though the scenes are happening live around the audience.

While some sounds immerse us in fantasy realms, everyday sounds can also move us profoundly by triggering memories and emotions. For This American Life, producers use snippets of found sound – birdsongs, passing trains, wind chimes, splashing water - as transitions between scenes. These quiet moments allow listeners to locate themselves inwardly between stories. Producer Starlee Kine explains: “The sounds let you sit back and feel your feelings at your own speed.”

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Using Music to Set the Mood

Music possesses unmatched power to instantly establish mood and emotional tone. While evocative sound design and vocal performances tell the explicit story, music works behind the scenes, subtly shaping how listeners receive and interpret the narrative. Masterful composers understand how to wield music's emotive force to guide the audience down specific psychological paths.

According to Elyse Willis, composer for narrative podcasts like Limetown and Blackout, "Music is incredibly direct emotionally - it triggers powerful, visceral responses." She constantly experiments with instrumentation and tone to elicit different reactions. For Limetown's eerie, dystopian vibe, she used disjointed strings and pulsating synths to provoke unease. Contrastingly, for romance podcast Passenger List, she crafted gentle piano and acoustic guitar pieces to underscore tender moments.

Willis explains that music elicits emotion by triggering our imagination. "Minor piano chords feel melancholy because we associate them with loss. Rumbling brass evokes power and danger because it sounds imposing to our ears." Composers intuit these intrinsic musical-emotional relationships and construct accompanying scores to align with the intended mood.

Director Dann Michael Thompson advises using restraint, since music's influence can feel manipulative if overdone. "You want to nudge listeners in the right direction, not shove them there with heavy-handed cues." He likes layering environmental sound effects to subtly establish tone without dictating feeling.

While some podcasts take a sparse approach, rich orchestral scoring can powerfully support fictional worlds when done artfully. Composer Mark Henry Phillips creates lavish compositions for Marvel podcasts, yielding potent emotional resonance. "For Wolverine, I wove intense strings, throbbing drums and snarling electric guitars to complement Logan's feral nature," he explains. For the mystical fantasy universe of X of Swords, Phillips used choirs, chimes and eclectic instruments like duduks and erhus to conjure an epic, otherworldly atmosphere.

Music also helps denote time and place. For the podcast Black Widow: Bad Blood, set in 1960s New Orleans, composer Ian Honeyman infused jazz arrangements with noirish edge to transport listeners back in time. For Cold War espionage thriller Marvel's Black Widow: First Vengeance, Phillips crafted spy-flavored lounge music sprinkled with Slavic flavors to immerse listeners in the Soviet setting.

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Silence Speaks Volumes

Silence is an incredibly powerful storytelling tool that allows listeners to actively engage their imagination. While sounds and music influence mood, strategic silence creates space for reflection and self-directed emotional response. Masterful podcasters and audiobook directors understand when quiet, unadorned moments can speak volumes.

According to Ira Glass, host of This American Life, audio storytellers must not shy away from silence and always avoid wall-to-wall narration. "You need to create gaps for the listener to inject their own reactions and interpretations of what's happening,” Glass explains. He frequently uses abrupt silences after emotional moments to let resonance linger. Without narrator explanation, the audience connects dots themselves.

Eli Horowitz, co-creator of the fiction podcast Homecoming, also embraces silence's receptive power. “We aren’t scared to have moments where something emotional happens and we just let it sit there without resolution,” he says. This space intensifies the feelings evoked and allows listeners time to process naturally.

Silence is especially impactful before dramatic turning points or revelations. According to radio drama director William Alland, strategic silence builds anticipation and “puts audiences on the edge of their seats." Alland, known for directing suspenseful radio dramas like The Shadow, advises, "Let the silence work for you - hold it an extra beat or two longer than seems comfortable." This tension enhances the force of whatever follows.

While silence builds drama, it also enables quiet intimacy. Dann Michael Thompson, audio director for Audible, says soft, unscored scenes feel remarkably personal. “Silence can draw the audience into a hushed space with the narrator - it’s like being in a dark room hearing someone whisper secrets,” he explains. Removing distraction directs focus to the voice’s subtle nuances.

Podcasters leverage uninterrupted first-person narration to achieve striking emotional intimacy. Shows like Limetown, The Left Right Game, and The Black Tapes use extended monologues to make listeners feel they are being addressed directly. Without soundtrack distractions, the narrator's bare words feel raw and immediate.

Untouched field audio also wields quiet power. The podcast S-Town derives much of its resonance from mundane tape - wind chimes tinkling, footsteps creaking on old floorboards, rain pattering on rooftops. These unadorned slices of life affect listeners more than any soundtrack could.

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Mixing for Maximum Emotional Engagement

Mixing is a subtle art that balances voices, sound effects, and music to craft an immersive emotional experience. While recording quality talent and incorporating impactful audio elements sets the foundation, the mix itself brings all components into harmony, unifying them into a transportive storytelling tapestry. Masterful mix engineers intuit how to spotlight key elements like dialogue while sculpting ambiences that envelope listeners subtly. Their adjustments elicit visceral reactions, allowing audiences to feel the narrative deeply.

According to Pete Simon, director of original fiction podcasts at Audible, mixing requires holistic thinking about the audience’s emotional journey: “We take care to ride the line between under- and over-stimulating listeners. Too sparse and scenes feel lifeless. Too dense becomes exhausting.” He rides volume faders continually, creating dynamic soundscapes that mirror the story’s emotional contours.

During a poignant moment from Sandra, an Audible Original drama, mixing engineer Drew Fradet smooths the background tone, allowing the dialogue to shine: “I dip everything else so you just hear the two characters connect. It really focuses the emotion." At a story peak, Fradet intensifies all elements to heighten the energy. “Mixing creates that rollercoaster ride.”

While dialogue generally stays front and center, critical sound effects punctuate key moments. In Battleground from Night Vale Presents, sounds of detonating suicide vests cut violently through a crowd scene, maximizing shock. “Sound perspective is like camera angles - close mic for intensity, wide ambiences for scope,” explains Fradet.

Setting the right overall loudness also influences reception. Billia explains, “For Wolverine, we kept levels louder and more compressed to make the action intense and in your face. Quieter moments let you get lost in characters’ heads.” Matching energy levels to the scene's tone guides how audiences feel it.

Mixing also sculpts time and place through ambient beds. For 1800s historical drama Sandra, Fradet layered languid strings, ticking clocks, and horse clops to establish a sense of stillness and antiquity. “The mix conjures the era even when we're just hearing characters talk,” he explains.

However, emotive power derives from restraint. According to Fradet, “It’s easy to overmix — to keep layering sounds until it feels suffocating. Great mixes have moments where things disappear entirely, creating pockets of quiet.” Selective minimalism leaves room for the imagination, engaging audiences more deeply.

Bring Your Audio to Life: How to Evoke Emotion with Sound Design - Testing Your Final Mix on a Range of Listeners

Once you've crafted your audiobook or podcast mix to perfection in the studio, the true test comes when unleashing it into the world. Will your immersive soundscape translate powerfully across various real-world listening environments? Testing the final mix on a diverse range of listeners is crucial to ensuring your audio achieves maximum engagement regardless of playback equipment and setting.

According to Pete Simon, Audible’s director of original fiction programming, beta testing across listening contexts helps identify final tweaks to make mixes more robust. “In the studio with high-end speakers, mixes sound pristine," he says. "But most people listen on tiny smartphone or laptop speakers, in noisy environments like cars or trains. Testing in real conditions ensures the mix works everywhere."

For narrative podcast Limetown, composer Elyse Willis asked trusted colleagues to sample mixes on their personal devices. “We had them listen in suboptimal scenarios - phone speakers, earbuds, car stereos, while walking outside. If the mix engaged them still, we knew it would captivate wider audiences,” Willis explains. The team made final EQ adjustments so critical dialogue cut through despite limitations.

Once levels are locked, many shows still offer alternate mix versions to expand accessibility. According to Matt Yocum, sound designer for Welcome to Night Vale, “We create a stereo extended mix for home listening with rich ambient beds. But we also deliver a mono, vocal-focused mix for mobile contexts." This adaptability allows their elaborate mixes to shine across settings.

Beta testing also provides valuable feedback on how mix elements impact emotions. When finalizing mixes for Marvel’s scripted podcasts, engineers have focus groups sample key scenes. According to sound designer Ryan Billia, listener feedback exposes flaws in the mix’s effectiveness. “If testers say music overrides a poignant moment or SFX distract from a plot twist, I rebalance things,” he explains. Subjective listener input fine-tunes mixes for optimal engagement.

For greater empirical rigor, Leslie Gaston-Bird, sound designer for Wolf 359 and Zero Hours, runs listening experiments analyzing biometric data. “We record testers' heart rates and skin conductivity while they listen,” she explains. These biological markers indicate spikes in dread, shock and other visceral reactions. “Seeing intense moments not eliciting response in the data lets me know the mix needs adjusting,” says Gaston-Bird. Biometrics scientifically confirm a mix's emotional power.
