About this app

Tone Generator: Sound & Sweep is an accurate, easy-to-use audio signal generator for testing speakers and headphones, sweeping frequencies, and masking sound.

GENERATE
• Any frequency from 1 Hz to 22 kHz — a fine slider plus exact numeric input
• Four waveforms: sine, square, triangle and sawtooth
• Left / Right / Both channel routing
• Frequency sweep from a start to an end frequency over a set time
• White, pink and brown noise for sound masking

PRESETS
• Subwoofer and bass test
• Headphone left/right check
• Audible range explorer — just for fun
• Noise masking with an auto-off sleep timer
• Dog whistle (ultrasonic)
• DTMF
• A440 tuning reference

BUILT FOR REAL USE
• The screen stays awake while playing, with an auto-off timer
• Remembers your last settings
• Works fully offline — no account, no sign-up
• Full-screen ads appear only at natural break points, never while you start or stop a sound

SAFE LISTENING
Sounds can be loud and high-pitched. Keep the volume low, especially with headphones. This is a general audio tool, not a medical device, and is not intended to diagnose or treat any condition.
