About

jsfxr is an open-source web app in the audio video category (sound effect generator). It opens in your browser, so there is nothing to install. You provide preset or parameter sliders and get sound effect audio. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (chr15m/jsfxr).
