Experience 40Hz audio stimulation through immersive 3D Spatial Audio. GLYMPHA delivers precise gamma-frequency pulse sound using Apple's PHASE framework — designed for anyone curious about this widely researched acoustic frequency. 40Hz is the frequency of gamma waves, the neural oscillations observed when the brain is actively engaged. Research institutions worldwide are studying the connection between this frequency and cognitive activity, though its effects in humans are still under investigation. GLYMPHA brings that stimulus to your hands in a rich, spatial audio experience. Fair warning: it's not a comfortable sound. That's exactly what makes it a clear, distinct stimulus worth experiencing. FEATURES ■ 40Hz Pulse Generation Generates precise 1ms short pulses at a 1,000Hz carrier frequency, repeated every 25ms to produce a 40Hz rhythm. Choose from sine, square, or triangle waveforms. Pulse frequency, width, and carrier frequency are all adjustable via slider. ■ 3D Spatial Audio — Apple PHASE Framework The sound source rotates around you in full 3D space. With head tracking–enabled AirPods Pro or AirPods Max, the audio feels anchored in the real world around you — not just inside your head. Adjustable rotation radius, speed, and direction. Fixed-position mode also available. ■ Volume Fluctuation — Breathing Rhythm Sync Gently varies volume in sync with a slow breathing rhythm (~6 breaths/min) to reduce monotony. Volume rises on a 4-second inhale and gradually fades on a 6-second exhale — supporting a natural breathing pace for longer sessions. ■ Background Sound Layer pink noise (ideal for focused work) or ocean waves (great for relaxation) over the 40Hz pulse to soften its harshness and make sessions more comfortable. ■ Preset Management — iCloud Sync Save, name, and manage all your parameters (volume, frequency, spatial settings, and more) as presets. Synced via iCloud across your iPhone and iPad seamlessly. No limit on the number of presets. ■ Sleep Timer Playback stops automatically after your set time — perfect for meditation or winding down before sleep. COMPATIBLE DEVICES · iPhone / iPad running iOS 17 or later · Head tracking requires AirPods Pro (1st generation or later) or AirPods Max · Works with built-in speaker, wired headphones, or Bluetooth audio IMPORTANT NOTICE The effects of 40Hz audio stimulation on human cognition and health are still under active research. GLYMPHA is not a medical device and is not intended for the diagnosis, treatment, or prevention of any medical condition. Please do not use this app for medical purposes.
