Built in the studio.
Engineered for the mind.
The Architect Behind the Audio
Two decades of relentless audio engineering.
Sigfre’s audio engine is built on over 20 years of diverse, hands-on production experience. This isn’t a product of the entertainment industry—it is the result of deep, technical mastery across the entire spectrum of sound design, mixing, and acoustic engineering. Every track, tone, and frequency is shaped by a veteran ear, ensuring the highest level of studio-grade precision required to actually shift your cognitive state.
The question was simple: what does the science actually say about frequency and cognition — and why does the consumer audio landscape do it so poorly?
Most brainwave apps use compressed audio, lossy streaming, and clinical-sounding interfaces that feel closer to a hospital than a studio. Sigfre is the opposite: lossless signal, phase-perfect playback, and a listening experience built for humans.
“I built Sigfre because I wanted to create something that genuinely helps people. Not another productivity tool — something that helps you align with the highest version of yourself through frequency, through intentional practice, through sound engineered with real purpose. That’s what Sigfre is built to do.”
The Audio Suite pairs with The Alignment Journal — a physical notebook designed around the same five neural states. Together they form a complete system for intentional focus, deep rest, and cognitive alignment.
The frequencies are isochronic tones and monaural beats engineered to work on any speaker. The ambient layers are recorded and produced in-house. Nothing is sampled, nothing is synthetic.

COMMON QUESTIONS
Who created Sigfre?
Sigfre was created by Tyler Fuller, a music producer with over 20 years of studio experience. He built it to apply the precision of professional audio production to personal development and cognitive performance.
Is Sigfre's audio AI-generated?
Every core Sigfre track — brainwave tones, Solfeggio frequencies, ambience — is crafted by a human producer and produced in-house. The one exception is Custom Subliminals: your own personalized affirmations, delivered in a premium studio-grade voice, generated on demand and woven undetectably beneath the mix.
What makes Sigfre different from other brainwave apps?
Sigfre uses monaural beats and isochronic tones instead of binaural beats, so it works on any speaker, not just headphones. It also lets you generate limitless Custom Subliminals — personalized affirmations woven undetectably beneath your mix — something no other brainwave audio platform offers.
What is 432Hz tuning and why does Sigfre use it?
432Hz is an alternative tuning standard that many researchers believe resonates more naturally with the human nervous system than the industry-standard 440Hz. Every Sigfre track is tuned to 432Hz from the ground up.
