SemRelux: Frequency App

180+ sounds — binaural beats, solfeggio tones, ASMR and colored noise. Sleep timer, background play, real cover art. One sound free every day.

Tune into calm. SemRelux is a beautifully simple sound player with more than 180 carefully crafted sessions — binaural beats, solfeggio tones, ASMR triggers and colored noise — designed for relaxation, focus, and better rest.

WHY SEMRELUX Sound has accompanied rest and reflection for centuries. SemRelux brings the most loved listening traditions together in one elegant, distraction-free player: pick a goal, press play, and let the sound do the rest. Every session pairs a precisely generated tone with a real recorded ambience — rain, ocean, fireplace, crickets, a night train, even a purring cat.

9 CATEGORIES, 180+ SOUNDS • Sleep — deep delta-band sessions and cozy soundscapes for winding down at night • Stress — gentle alpha-band tones for unwinding after a long day • Focus — steady pulsed beats to accompany work, study and deep work sessions • Meditation — theta-band soundscapes for stillness and mindfulness practice • Energy — brighter tones for a refreshing midday reset • Healing sounds — classic solfeggio tones such as 528 Hz, traditionally associated with renewal and balance • Anxiety relief — soft, slow tones designed for quiet moments of calm • Creativity — flowing alpha rhythms to keep ideas moving • ASMR — tapping, brushing, crinkling, page turning and gentle sleep triggers

TINNITUS RELIEF & COLORED NOISE Soft masking soundscapes for quiet moments, plus a full palette of colored noise — white, pink, brown, green, blue and grey — calibrated for relaxation and focus.

BINAURAL BEATS Binaural beats play a slightly different tone in each ear, and you perceive the difference as a gentle rhythmic pulse. Put on headphones for the full binaural effect — solfeggio tones, ASMR and noise sound great on any speaker.

SOLFEGGIO TONES Explore the classic solfeggio scale — 174, 285, 396, 417, 432, 528, 639, 741, 852 and 963 Hz — pure, precisely generated tones traditionally associated with relaxation and balance.
