A Sesap uses (playing slightly different frequencies in each ear) and isochronic tones (pulsed tones) to gently nudge your brainwaves toward a target state. But unlike a static 15-minute track, the Sesap monitors your EEG (via Muse headband or similar) and adjusts the frequency drift in real-time to keep you locked in.
Most audio apps try to change your mood. A Sesap first mirrors it. If you are angry, playing lullabies will frustrate you more. The Sesap listens to your voice stress patterns and says, "I hear tension." It then plays low, growling industrial textures mixed with heavy rain—matching your anger. After 90 seconds of mirroring, it slowly introduces a calming middle frequency, guiding you out of the state. This is called "pacing and leading" in neuro-linguistic programming. sesap audio companion
