Frequently asked questions
How does the sound effect generator work?
It synthesises audio in real time with the Web Audio API using classic sfxr-style parameters (waveform, envelope, frequency slide, arpeggio).
Can I export the sounds?
Yes — every effect can be downloaded as a 16-bit WAV ready to drop into any game engine.
Are the sounds royalty-free?
Yes. You generate them yourself and own the output; use them in commercial games freely.
