Web Audio Modular Synthesizer & Sound FX Generator
A full synth voice designer running entirely in your browser: seven oscillator flavors (sine, saw, triangle, square with real PWM duty control, white/pink/brown noise), a visual ADSR envelope, resonant biquad filtering, an LFO routed to pitch, filter or gain, and an effects chain of tanh overdrive, stereo ping-pong delay and Schroeder reverb. Play the two-octave keyboard with your mouse, the printed computer keys (A W S E D…) or a Web MIDI controller, watch the live FFT spectrum and scrolling waterfall spectrogram, fire retro game SFX one-shots (jump, laser, coin, powerup, explosion, click), then export your sound as 8/16/24-bit WAV or as dependency-free Web Audio code you can paste into any project.
