Sound Generator

Sound Generator is a precision signal toolkit that runs entirely in your browser, built on the Web Audio API. Set an exact frequency from 1 Hz to 20 kHz in sine, square, sawtooth or triangle, play it, and export the result as a 16-bit WAV. From there, 17 tools cover the everyday audio testing jobs: multi-oscillator tones, linear and exponential sweeps, white, pink and brown noise with band shaping, alarm patterns, binaural beats, instrument tuning references for 14 tunings, an accurate metronome, the full DTMF keypad, the BBC pips, a step-through hearing test, subwoofer test signals, plus voice generation, microphone recording, pitch shifting and time stretching. Every setting lives in the URL, so any tone is shareable as a link. Nothing is uploaded: signal generation and file export both happen on your own device, with no account, no ads and no behavioural tracking. It is for people who need a reliable reference signal quickly: audio engineers and technicians calibrating gear, speaker and hearing checks, musicians tuning by ear, developers testing telephony and audio pipelines, and anyone who needs a clean tone right now.
