Zynth

Zynth is a professional-grade sound effect synthesiser built for creators who need results fast. Whether you're a game developer hunting for that perfect coin pickup, a filmmaker needing a sharp UI blip, or a musician exploring synthesis — Zynth puts a full sound design studio in your pocket. POWERFUL SYNTHESIS ENGINE Zynth generates audio entirely from scratch using a hand-tuned DSP engine — no samples, no loops, no limitations. Dial in exactly the sound you hear in your head. • 7 waveforms — Sine, Square, Sawtooth, Triangle, Pulse, Trapezoid, and Noise • Exponential pitch sweep for classic laser, coin, and power-up effects • Vibrato with adjustable rate and depth • Overtone oscillator for rich, layered tones • 3-mode filter (Lowpass, Highpass, Bandpass) with sweepable cutoff frequency • Full AHDR envelope — sculpt the exact attack, hold, and decay of every sound STEP SEQUENCER Chain up to 4 unique sounds into a sequence and fire them all with a single tap. Adjust step timing to create everything from rapid-fire retro blips to slow, dramatic sweeps. EXPORT ANYWHERE Every sound you create is yours. Export your sequence as a high-quality WAV file directly to your Downloads folder — ready to drop straight into your game engine, DAW, or video editor. SAVE & SHARE CONFIGURATIONS Save your favourite sounds to an on-device library and recall them instantly. Export and import synth configurations as JSON files to share your creations or back them up — fully compatible across devices. BUILT-IN PRESETS Hit the ground running MAKE IT YOURS Choose from light or dark theme and eight accent colours to match your personal style. Zynth looks as good as it sounds.
