ENGINEER YOUR SUBCONSCIOUS AT ZERO TIME COST. Most audio tools force a bad trade: sit in silence listening to generic tracks you don't have time for, or rely on stereo binaural beats that collapse the moment you listen on a single AirPod or external speakers. Sigfre is built differently. Powered by our patent-pending sub-perceptual audio engine, Sigfre pairs phase-coherent monaural beats and isochronic tones with custom Neural Scripts engineered to play concurrently underneath Spotify, Apple Music, YouTube, or podcasts. THE PATENT-PENDING AUDIO ENGINE • Phase-Coherent Monaural & Isochronic Synthesis: Unlike binaural beats that require stereo separation, Sigfre generates mathematical amplitude modulation in the physical waveform itself. Get 100% entrainment depth on a single AirPod, studio monitors, or both headphones. • Sub-Perceptual Neural Scripting: Record or generate custom first-person Neural Scripts tailored to your exact identity and goals. • 300Hz–3.4kHz Spectral Pocket Filtering: Vocal scripts are dynamically filtered and gain-coupled to sit at a calibrated sub-perceptual offset beneath the carrier wave—never clashing with basslines or lead vocals in your music. • Seamless Zero-Click Loop Mastering: Every Delta, Theta, Alpha, Beta, Gamma, and Solfeggio carrier is phase-aligned for uninterrupted cognitive immersion. THE 90-DAY ALIGNMENT PROTOCOL • Daily Validated Sessions: Build compounding neural momentum with structured daily tracking across a 90-day trajectory. • Background Audio Coexistence: Toggle "Play With Other Apps" to layer your protocol seamlessly beneath your daily workflow, workouts, or study sessions. • Physical & Digital Integration: Pairs directly with The Alignment 90-Day Frequency & Manifestation Journal. One validated session a day. No exceptions. SUBSCRIPTION & TERMS Sigfre offers an auto-renewing annual subscription (with a 7-day free trial) and an auto-renewing monthly subscription to unlock full access to the 90-Day Protocol, custom Neural Scripts, and background mixing.
