ToneAtlas
Tones, Sweeps & Binaural Beats
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Precision tones from 0.1 Hz to 100 kHz with independent control of each ear. Binaural beats, sweeps, noise - and see which animals hear what you can't.
ToneAtlas is a precision tone generator built around one idea: you have two ears - control them independently.
PER-EAR CONTROL
Play one frequency in your left ear and another in your right. Independent waveform, volume, mute and phase for each ear, with one-tap swap. Invert or phase-shift the right channel to test speaker wiring and stereo imaging.
FULL SPECTRUM: 0.1 Hz - 100 kHz
Go far beyond human hearing. Every slider shows where you are in the spectrum - and when you leave the human range (20 Hz - 20 kHz), ToneAtlas tells you who can still hear it: elephants and whales in the infrasound, dogs, cats, bats and dolphins in the ultrasound, and the scientific instruments that detect what no animal can.
BRAINWAVE BEATS
Binaural beats with Delta, Theta, Alpha, Beta and Gamma presets - plus monaural and isochronic modes that work on speakers. Adaptive sessions glide the beat frequency over time, easing you from relaxed to asleep.
