Signal & Wave Generators
Sine, square, triangle, sawtooth, and pulse wave generators. White, pink, and brown noise for sleep, focus, and testing. Frequency sweep generator, multi-frequency mixer, FM/AM modulation, and subharmonic synthesis — for sound designers, audio testers, and electronics students.
Available Tools
Sine Wave Generator (Tone Generator)
Generate precise tones with 4 waveforms (sine, square, triangle, sawtooth), interactive piano, ADSR envelope, noise modes, hearing test, and WAV export.
Launch tool →Square Wave Generator
Generate square waves with adjustable duty cycle (0–100%), real-time waveform and harmonic spectrum showing odd harmonics, and audio playback at any frequency.
Launch tool →Triangle Wave Generator
Generate soft triangle waves with adjustable frequency, symmetry control, harmonic analysis showing 1/n² odd harmonics, and waveform comparison mode.
Launch tool →Sawtooth Wave Generator
Generate harmonically rich sawtooth waves with ramp-up/ramp-down toggle, all-harmonic spectrum display (1/n rolloff), and waveform comparison with other shapes.
Launch tool →Pulse Wave Generator
Generate pulse waves with adjustable pulse width (1–99%) and an automatic PWM sweep LFO. Watch harmonic content change dynamically as the duty cycle varies.
Launch tool →White Noise Generator
Generate white noise for sleep, focus, studying, or audio testing. Volume control, sleep timer (15/30/60 min), flat spectrum visualization, and WAV download.
Launch tool →Pink Noise Generator
Generate pink noise (−3 dB/octave) for speaker calibration, room measurement, and sleep. Log-frequency spectrum, measured slope readout, sleep timer, WAV download, and A/B/C white-pink-brown comparison.
Launch tool →Brown Noise Generator
Generate deep brown noise (−6 dB/octave) for ADHD focus, deep relaxation, and sleep. Log-frequency spectrum with slope reference, measured-slope readout, sleep timer, WAV download, and A/B/C white-pink-brown comparison.
Launch tool →Frequency Sweep Test Generator
Generate linear or logarithmic sine sweeps across 20–20,000 Hz with custom range and duration. One-shot, repeat, ping-pong loop modes. Live visual current-Hz marker plus a mark-threshold hearing-test feature.
Launch tool →Multi-Frequency Mixer
Mix up to 4 simultaneous oscillators with independent frequency, amplitude, and waveform. Chord, interval, DTMF, beat, and harmonic-series presets. Live combined waveform and spectrum plots.
Launch tool →Frequency Modulator Tool
2-operator FM synthesis with carrier and modulator controls, modulation-index slider, live waveform and Bessel-sideband spectrum, and 10 preset patches (bell, electric piano, bass, metallic, wood drum).
Launch tool →AM Signal Generator
Amplitude modulation: carrier × (1 + m·cos). Adjustable carrier, message, and depth (0–200%) with over-modulation warning. Live envelope waveform and 3-line spectrum (carrier + ±fm sidebands).
Launch tool →FM Signal Generator
Radio-engineering FM with explicit Δf deviation slider, live instantaneous-frequency readout, Carson-rule bandwidth markers, and broadcast-style presets (NBFM, WBFM, NTSC, aviation).
Launch tool →Subharmonic Generator Simulator
Generate the first 4 subharmonics (f, f/2, f/3, f/4) of a fundamental with independent amp / waveform / mute. Bass enhancement, organ pedal, missing-fundamental, and sub-bass test presets.
