Knowledge Base

How to Use the Synthetic Sound Generator

The Synthetic Sound Generator builds sounds from scratch in your browser with the Web Audio engine, no samples, no uploads. Pick one of eight sound types, shape it with the parameter controls (or start from a preset), preview it live, then render and download a WAV. Everything is synthesised locally and released public-domain (CC0), so it's ready to drop straight into games, films, videos, podcasts, and music.

The Eight Sound Types

Bass Synth: Deep low-end, sine/square/triangle/saw through a real resonant lowpass (cutoff + Q).
Lead Synth: Melodic single-note tones with a full ADSR envelope and adjustable vibrato.
Pad: Lush two-oscillator texture with slow LFO drift, ideal for long background beds.
Kick Drum: Pitch-swept sine with punch and decay control.
Snare: Filtered-noise crack blended with a tuned body tone.
Hi-Hat: Bright, resonant filtered-noise hit with density and decay.
Ambient Texture: Multi-voice detuned drone with slow modulation, atmospheric beds.
Riser / FX: Frequency sweep with a selectable curve for transitions and build-ups.

Presets & Live Preview

Each sound type ships with four one-click presets (a kick's Tight, Boomy, Punchy, Deep, a bass's Deep Sub, Punchy, Gritty, Round). A fast starting point you can then fine-tune. Hit Test to hear the sound loop while you adjust any control in real time. What you hear is exactly what you download.

Rendering & Output

Duration: From a fraction of a second up to long beds. Pad and Ambient use seamless looping, so you can render minutes-long backgrounds without exhausting device memory.
Sample Rate: 44.1, 48, or 96 kHz. The tool shows the maximum safe length for your device at the chosen settings.
Bit Depth & Channels: 16- or 24-bit, mono or stereo.
Download: Renders to a standard WAV, peak-limited so it never clips, ready for any DAW or editor.

License & Usage Rights

Every sound you generate with the Synthetic Sound Generator is released into the public domain under the Creative Commons Zero (CC0 1.0) dedication. You can use it however you like (in commercial games, films, videos, podcasts, apps, or music) with no royalties, no attribution, and no restrictions. You don't need to ask permission or credit Infinite Creation, though a mention is always appreciated. The audio is synthesised locally in your browser, so the files are entirely yours the moment they're created.

FAQ

Q: Can I use generated sounds in commercial projects?
A: Yes. Every sound is released into the public domain under CC0 1.0. Use it commercially or personally, with no royalties and no attribution required.

Q: How do I mix generated audio with dialog or music?
A: Keep generated ambient quiet (-18 to -24 dB relative to voice). It supports, never competes.
