## Description

Tone Generator — Pure, Precise Audio Signals<br><br>Generate clean test signals from 20 Hz to 20 kHz directly on your phone: steady tones, noise and sweeps. A minimalist instrument for musicians, sound engineers, students, and anyone who needs a reliable signal source on the go.<br><br>TONES<br>• 20 Hz to 20 000 Hz on a logarithmic slider, with ±1 Hz buttons and direct entry for exact values<br>• Three waveforms — Sine (pure tone), Square (rich harmonics), Triangle (warm timbre)<br>• Musical note display — shows the closest note (A4, C♯5, and so on)<br>• Quick presets for 432, 440, 528 Hz and 1 kHz, plus your own pinned frequencies<br><br>NOISE<br>• White, pink and brown noise, generated continuously — never a looping sample<br><br>SWEEPS<br>• Glide between two frequencies over 5 to 120 seconds<br>• Linear or logarithmic, one-shot or looping<br>• The readout follows the signal as it runs<br><br>BUILT FOR REAL WORK<br>• Route the signal to the left speaker, the right, or both — test one channel at a time<br>• Keep the screen on so a measurement is never cut short<br>• Auto-stop after 5, 15, 30 or 60 minutes<br>• Pauses for calls and stops when headphones are unplugged, so a pure tone never lands in your ears at full volume<br>• Dark and light themes, tablet layout, 14 languages<br><br>AUDIO ENGINEERING<br>• Band-limited synthesis using PolyBLEP and PolyBLAMP — no harsh aliasing artefacts<br>• The device&#39;s native sample rate, so nothing is resampled on the way out<br>• Waveforms matched for equal loudness: changing shape changes timbre, not level<br>• Every transition — start, stop, sweep seam — is ramped, so there are no clicks<br><br>HEARING SAFETY<br>Pure tones concentrate all their energy on one frequency and feel deceptively quiet. The app opens with a short safety notice and keeps it one tap away.<br><br>This app is not a medical device.<br><br>Made by KirsuLab LLC.
