Description
Tone Generator — Pure, Precise Audio Tones
Generate clean, accurate test tones from 20 Hz to 2000 Hz directly on your phone. Tone Generator is a minimalist audio frequency tool for musicians, sound engineers, students, and anyone who needs a reliable signal source on the go.
FEATURES
• Frequency range from 20 Hz to 2000 Hz with a logarithmic slider for natural pitch navigation • Three waveforms — Sine (pure tone), Square (rich harmonics), Triangle (warm timbre) • Tap-to-edit frequency field — enter exact values like 432, 440, 528, or any value between 20 and 2000 Hz • Quick preset buttons for 432 Hz, 440 Hz, and 528 Hz • Musical note display — shows the closest note (A4, C♯5, etc.) for any frequency • Dark and light themes • Haptic feedback on slider movement for tactile precision
AUDIO ENGINEERING
• Band-limited synthesis using PolyBLEP and PolyBLAMP — no harsh aliasing artefacts, even at higher frequencies • Smooth gain envelopes — no clicks or pops at start or stop, on any device • Continuous-phase frequency changes — slide smoothly without zipper noise • 44.1 kHz / 16-bit PCM playback through your device's standard media output
USE CASES
• Tune musical instruments without a tuning fork • Calibrate audio equipment, headphones, and studio monitors • Run quick hearing checks across the audible range • Generate reference tones for ear training and pitch identification practice • Explore acoustic resonance and standing waves • Test speakers and detect rattles or buzzes • Demonstrate physics of sound to students
DESIGNED FOR FOCUS
Tone Generator is single-purpose by design. No menus to dig through, no profiles to set up, no login, no microphone access, no location tracking. Open the app, pick a frequency, hit Play.
HEARING SAFETY
The app shows a hearing-safety notice on first launch and keeps it one tap away from the info icon at any time. Please start at a low volume, take regular breaks, and never use a tone generator at uncomfortable levels — especially through headphones.
