Tone Generator: Frequency Test

Tone Generator: Frequency Test is a focused local audio tool for creating steady tones, running frequency sweeps, and playing white, pink, or brown noise. It is designed for music practice, audio enthusiasts, and everyday equipment checks.

Set a precise frequency from 20 Hz to 20 kHz and choose a sine, square, triangle, or saw wave. Fine steps, output level, and left/right balance help you create the test signal you need quickly.

Frequency Sweep smoothly moves from a start frequency to an end frequency. Choose linear or logarithmic sweep behavior, set a duration, and repeat the sweep when needed. It is useful for routine speaker, headphone, and audio-chain checks.

The noise tool includes white noise, pink noise, and brown noise with high-pass, low-pass, timer, and balance controls. Select mono, stereo, left, or right output to check individual audio channels.
