Speak or type — Soren is here.
Tuning dial — targeted presets
Research-supported targets (entrainment frequency)
Traditional / solfeggio & chakra (carrier tone)
Honest labeling: the top group targets brainwave bands with published research behind
them — 40 Hz gamma is the most studied. The solfeggio and chakra tones are exact to the
traditional frequencies (396.0, 528.0, 963.0 Hz and so on) but they come from spiritual
tradition, not clinical trials. They're included pitch-perfect so you can work with them
however you choose. Tap a preset to start it — tap again to stop.
Tone — the pure signal
Brain bath — 3D orbiting rain
Heavy rain rendered as a 3D sound source that physically orbits your head —
circling ear to ear, sweeping from the base of your neck up over the crown to your
forehead, then washing down again. Uses HRTF spatial audio, so
headphones are essential for this one. Starts the moment you switch it on.
Soundscape layers — tap to play, stack freely
Each layer starts on its own the moment you tap it — no tone required — and stops
when you tap it again. Stack as many as you like, mix them under the tone, or run them solo.
Appearance — themes & dreamscape
Or let Soren paint the room live: an AI-generated scene fades in behind the instrument.
Uses your xAI (Grok) key if saved — otherwise the free Pollinations engine.
Ask by voice, too: "paint the room like a violet nebula."
Session
Binaural: left ear carrier, right ear carrier + frequency.
Keep the tone barely audible under the layers. This button starts the tone —
and stops everything when pressed again.
