Sound Healing

Sound Healing is a tool to feel (on the body) and visualize sound in a professional yet effortless way. It generates pure tones at the frequencies known from the vibrational tradition, frequencies for body areas, binaural beats — and analyzes in real time any audio captured by the microphone, showing its waveform, frequency spectrum, and spectrogram. Designed for those who practice meditation, vibrational exposure, music therapy, naturopathy, or anyone who simply wants to explore the nature of sound with a serious, intuitive, and visually polished tool. INCLUDED FREQUENCIES • Beneficial Solfeggio: 174, 285, 396, 417, 432, 528, 639, 741, 852, 963 Hz — each frequency with a traditional description of its use • Body areas: 7 frequencies associated with the body's main areas, from the base of the spine to the crown • Binaural beats: Delta, Theta, Alpha, Beta, Gamma presets (stereo headphones required) • Frequencies for organs and body systems: nose and throat, lungs and bronchi, liver and pancreas • Relaxation frequencies: 333, 444, 888, 999, 1111 Hz — high-frequency series • Themed programs: Relaxation/anxiety, Sleep, Tension, Meditation, Energy/focus — ready-to-use sequences • Custom frequencies: set any value from 20 to 20,000 Hz REAL-TIME AUDIO ANALYSIS Capture audio from your internal or external microphone and visualize: • Waveform (oscilloscope) • Frequency spectrum with FFT and labeled peaks • Waterfall spectrogram (frequency/time map) • Pitch indicator in cents (deviation from tuning) • Level meter (VU) CUSTOMIZATION • Adjustable reference tuning (432 Hz, 440 Hz) • Free selection of input and output audio devices • Playback timer with auto-stop • Binaural mixing for any frequency • Capture and save custom presets PRIVACY AND PERFORMANCE Sound Healing is a fully offline application. It does not collect, transmit, or store any data on external servers. Audio captured is analyzed in real time but never recorded. All data stays on your Mac. Compatible with macOS 13 and later. Universal binary: runs natively on Intel Mac and Apple Silicon. WHO IT'S FOR • Naturopaths, wellness practitioners, music therapists • Sound healers, users of harmonic singing bowls and tuning forks • Sound enthusiasts and acoustics lovers • Anyone looking for a visual companion to relaxation sessions DISCLAIMERS Sound Healing is a tool for sound exploration and personal wellness support. It is not a medical device and does not replace professional diagnosis, therapy, or treatment. Do not use in case of: photosensitive epilepsy or uncontrolled seizure disorders, high-risk pregnancy, pacemaker users not tested for audio stimulation, severe psychiatric conditions in acute phase. Binaural beats require stereo headphones. Keep the volume at moderate levels. For any medical condition, always consult a qualified professional. — Developed by Massimo Del Pizzo, naturopath.
