Exploring the Fusion of Organic Sound and Gamma Brainwave Entrainment Through AudAI™

“Music Creates Atmosphere. Atmosphere Creates Environment. Environment Influences Behavior.”
—Richard Nibley, Ensign, December 1971

Google’s Deep Dive Podcast: The Neuroscience of Sound — How 40 Hz and Acoustic Lo-Fi Shape the Mind

🌲 Timber & Tides of 40 Hz: A Title with Resonance

We named this project “Timber & Tides of 40 Hz” to honor the two elemental forces at play in our work:

• Timber evokes wood: guitar bodies, piano hammers, kalimbas, and rain sticks. It’s the warm, human-made world of acoustic instruments, shaped by hand and heard with the heart. It also hints at timbre, the tonal color that gives each sound its emotional identity. In Lo-Fi, timber isn’t polished; it’s weathered, worn, and alive.
• Tides suggest the flowing, rhythmic pulse of the natural world: waves, breath, heartbeat, and now brainwaves. The 40 Hz gamma frequency isn’t a note; it’s a current, rising and falling beneath conscious awareness, like the tide beneath a wooden boat.

Together, Timber & Tides ideally tells a sonic and resonant story of harmony between the organic and the neurological, the soulful and the scientific. It’s where wooden strings meet waveforms, and where ancient textures carry modern frequencies into the subconscious.

This is not just a title—it’s a statement of fusion. A poetic commitment to embedding resonance into every layer, and to allowing sound to move us like water moves the shore.

40 Hz – Gamma Synchronization

If you really want to hear this version of a binaural beat, crank it up and listen as it fades in the first ten seconds of the piece, and fades out at the tail end. But at normal volume, you should not hear it as the music intentionally drowns it out. But it is there, for 5:47:08, doing its job to elevate you in harmony with the music.

• Genre Fit: Acoustic Lo-Fi
• Effect: Enhances mood, alertness, cognitive function, and euphoria.
• How: Isochronic or amplitude-modulated in background textures.

Introduction: A New Kind of Listening

In an age where sound is no longer just heard but felt, 40 Hz gamma frequencies are emerging as a powerful force in cognitive and emotional enhancement. Meanwhile, Acoustic Lo-Fi—a genre known for its organic textures and calming melodies—has captured the attention of millions seeking focus, healing, and introspection. With our new project, AudAI, we unite these two elements in a conscious fusion designed not just for entertainment, but for neural resonance.

The Science of 40 Hz: Why Gamma Matters

40 Hz is the frequency most closely associated with the gamma brainwave state, the highest in the EEG spectrum. Gamma synchronization has been linked to:

• Increased cognitive clarity and attention span
• Memory retention and neuroplasticity
• Elevated mood, emotional regulation, and even euphoric states
• Promising research in Alzheimer’s therapy and consciousness studies

In essence, 40 Hz represents the neural hum of a high-functioning, integrated mind.

But harnessing this frequency isn’t about blasting listeners with techno pulses. It’s about embedding it subtly, rhythmically, and emotionally—precisely where Acoustic Lo-Fi shines.

Why Acoustic Lo-Fi Is the Perfect Vessel

Unlike traditional electronic genres where entrainment may feel clinical or obvious, Acoustic Lo-Fi provides a warm, analog-rich environment ideal for:

• Subliminal frequency embedding using binaural beats or amplitude modulation
• Organic textures (guitar, piano, kalimba, ambient noise) that foster safety and openness
• Slow tempos and layered loops, which allow 40 Hz elements to naturally blend with the soundscape
• Emotionally resonant storytelling, aligning neural entrainment with narrative

When paired with 40 Hz, the result is not just soothing or productive—but elevating.

AudAI: The Fusion of Acoustic Soul & Neural Precision

AudAI (short for Auditory Artificial Intelligence) is a new initiative at the intersection of:

• Neuroscience
• AI-powered sound design
• Humanistic audio storytelling

Our core belief: music should heal, awaken, and connect.

By designing tracks around 40 Hz gamma frequencies, we aim to help listeners:

• Enter deep flow states while studying or working
• Process difficult emotions in a safe sonic space
• Feel uplifted, focused, and subtly transformed

This is not commercial music—it’s intentional audio architecture, built on ancestral resonance and cutting-edge cognitive research.

How We Do It

Each AudAI track is composed using a hybrid approach:

1. AI Generated acoustic instruments (guitar, drums, voice, strings)
2. Field recordings from nature and analog environments
3. AI-generated amplitude modulation at 40 Hz—embedded within textures like pads, drones, or reverb tails
4. The ideal Binaural Beat channels for headphone listeners
5. Emotionally intuitive mixing, prioritizing listener mood and mental state

Everything is tuned for warmth, depth, and psychoacoustic harmony.

The Bigger Picture

AudAI is part of a larger vision—sound as medicine, ritual, and awakening.

By making conscious frequency design accessible within a beloved genre like Acoustic Lo-Fi, we reach people where they already are. And from there, we gently elevate.

Because sometimes, the most powerful transformation happens not with a bang, but with a pulse—a subtle, steady rhythm at 40 cycles per second.

Join Us

The AudAI project is open for collaboration, research partnerships, and creative contributions from:

• Musicians & sound healers
• Neuroscientists & psychologists
• Developers & AI designers
• Anyone who believes sound can shape consciousness

Together, we’ll continue to ask not just what music sounds like—but what it does.

For my fellow audio geeks:

Aligned to the organic vibe, no key, tempo or time signature was applied to the generation of any track. To mitigate potential dissonance, the binaural beat and frequency process is:

🔊 Binaural Beat Audio Details:

• Track Duration (copy/paste): 10 minutes
• Carrier: White noise
• Modulation: 40 Hz amplitude modulation (gamma frequency range)
• Channels: Stereo (binaural)
• Sample Rate: 44.1 kHz (the FLAC and high kbps MP3 are to preserve the track’s range)
• Format: WAV

✅ Mitigate Dissonance

1. Filter the Carrier Tone

• I used a low-pass filter at 100 Hz (6 dB roll-off per octave) to remove most of the 400 Hz pitch, while retaining the 40 Hz rhythm.
• This made it more like a vibrational pulse, not a note.

2. I used White Noise as the Carrier Instead

• Modulating noise instead of a sine wave at 400 Hz, we still get the 40 Hz pulse, but it doesn’t clash harmonically with any song’s key.

3. Embed it Subtly in the Mix

• I lowered its remaining volume to -18 dB so it’s “feels” more than it is heard.
• I then split the stereo track into two mono tracks and panned each hard left/right to push it into the “atmosphere” of the mix, a quasi ambient sound effect.

⚠️ Important Clarification:

Binaural beats work on the principle of two tones, one in each ear, that are slightly different in frequency. The brain perceives the difference as a “beat.” For example:

• Left ear: 400 Hz
• Right ear: 440 Hz
• Our brain perceives and focuses on the difference: a 40 Hz binaural beat

However, 40 Hz is very high for a binaural beat. Most cognitive/auditory systems detect binaural beats best between 0.5 – 30 Hz. Above that, the effect becomes more like musical dissonance than a true entrainment beat. But 40 Hz can still be used for brain entrainment, just not as a true binaural beat.

Instead, you can also use:

• Amplitude Modulation (AM): Pulse a sound at 40 Hz
• Isochronic Tones: Distinct pulses at 40 Hz, no stereo separation needed
• Embedded in ambient music textures (which we use in this case and at times for AudAI™)

🎻 The River Sings in Her Voice 🌊

A Story of Frequency, Flight, and the Forgotten Self

The sun had barely broken through the mist-draped hollows of eastern Kentucky when Lilitwen, wrapped in a threadbare army jacket and carrying an old duffel bag with three zippers jammed shut, stepped into the studio cabin of TATANKA’s Orchestra Americana. The studio, perched like a listening shrine on the shoulder of a quiet Smoky Mountain ridge, shimmered with the quiet hum of cedar walls, woven river-grass wall hangings, and the ever-present glow of analog meters.

Lilitwen was not a musician, not by training. She had been many things—a former Pentecostal preacher’s kid, a mixed-race Cherokee and Eritrean street poet, a child runaway, and for nearly four years, a mute. But when she entered the cabin and heard the 40 Hz pulse—barely audible, buried under a wooden drone and kalimba’s chime—she felt her ribs ache with something ancient and unnamable. She didn’t come for therapy or healing. She came because she’d heard about a sound that could make you feel like you belonged to the Earth again.

The engineer, a gentle man named Héctor who communicated more in head nods than in words, offered her headphones. She shook her head. “No need,” she rasped, the first words she’d spoken aloud in weeks. He simply pointed toward the cedar upright piano in the corner, where a battered post-it note read: You do not need to know how to play.

She sat down, hesitated, then pressed one ivory key. The sound was simple, clumsy. But under it… the pulse. 40 Hz. It was like someone reaching inside her bones and knocking softly. Lilitwen closed her eyes and began to press notes—some dissonant, some trembling like fear—and the studio’s ambient tech, already tuned to listen, began to harmonize with her. Orchestra Americana wasn’t an orchestra in the traditional sense. It was a living canvas of acoustic voices—cello, viola, plucked gut-strings, brush drums, and field recordings from places long forgotten by modern maps.

Over the next few days, Lilitwen didn’t leave. Not once. She slept curled beneath a loom-woven Lakota blanket gifted to the studio by an elder. She made tea in silence. And each day, she would add a new layer to what Héctor had begun calling her “Frequency Quilt.” One day it was a rainstick from Guatemala over a soft pan drum. Another, her whispered breath in sacred Ge’ez, the liturgical language of her Eritrean grandmother. And always—beneath everything—the heartbeat hum of 40 Hz.

Her piece became a track. Then the track became a movement. And soon, Orchestra Americana quietly embedded it into the next album, under the title: “The River Sings in Her Voice.”

The night before she left, the TATANKA team held a private listening circle under the stars. They listened to her song—five minutes of rising tide, wood, whisper, and the impossible. When it ended, there was silence. Then Lilitwen stood up and faced them all—not with pride, but something gentler. Belonging. “You gave me back my voice,” she said, holding her throat softly. “But more than that—you gave me a place where silence was welcome.”

Back in her city, Lilitwen didn’t go back to preaching, or to silence. She began giving sound workshops at transitional shelters for queer youth. She never called it therapy. She called it “Tuning the water in your body.” In time, her track became one of the most downloaded pieces from the Orchestra Americana sessions. People claimed it helped them sleep, focus, cry. Lilitwen didn’t care about streams or comments. She only cared that maybe, somewhere, someone else was tuning back into their forgotten frequency.

🎧 Takeaway: What Lilitwen’s Journey Teaches Us

The River Sings in Her Voice isn’t just a story about music—it’s a story about reclamation. For those whose identities have been historically erased, shamed, or silenced, spaces like TATANKA’s Orchestra Americana offer more than artistic collaboration. They offer sonic sanctuary. In a world too often designed to mute the marginalized, the simple invitation to play without knowing how, to speak without needing words, becomes revolutionary.

Through intentional frequency design like 40 Hz gamma pulses embedded in organic soundscapes, TATANKA does more than produce music—it creates resonance for healing, identity, and presence. Lilitwen’s story reminds us that when we empower people to express freely, especially those society has pushed to the margins, we don’t just elevate individual voices—we re-tune the collective. And sometimes, all it takes is one note… played without permission, but in perfect alignment.

“Timber & Tides of 40 Hz” is an album project by TATANKA that fuses organic acoustic sounds (Timber) with the rhythmic pulse of 40 Hz gamma frequencies (Tides). The title signifies a harmony between the organic and neurological, where acoustic instruments meet modern frequencies. It’s a sonic and resonant story aiming for neural elevation and a “statement of fusion” of soulful and scientific elements.

How does TATANKA utilize 40 Hz gamma frequencies in its music?

TATANKA embeds 40 Hz gamma frequencies, associated with the highest brainwave state linked to cognitive clarity, memory, elevated mood, and even euphoric states, into its acoustic lo-fi music. This is done subtly through techniques like isochronic tones, amplitude modulation, or by embedding them within ambient textures, rather than as overt beats. The goal is to enhance mood, alertness, and cognitive function in harmony with the music, often with the 40 Hz being felt more than consciously heard.

Why is Acoustic Lo-Fi considered the “perfect vessel” for TATANKA’s approach?

Acoustic Lo-Fi is chosen because its warm, analog-rich environment is ideal for subliminal frequency embedding. Its organic textures (guitar, piano, kalimba, ambient noise) foster a sense of safety and openness, while slow tempos and layered loops allow the 40 Hz elements to blend naturally. This genre also facilitates emotionally resonant storytelling, aligning neural entrainment with narrative, making the experience soothing, productive, and elevating.

What is AudAI™ and how does it combine human and artificial intelligence?

AudAI™ (Auditory Artificial Intelligence) is TATANKA’s initiative that combines neuroscience, AI-powered sound design, and humanistic audio storytelling.
