I've made a free online tool for wavetable creation. Its a modular synthesis engine / oscillator that can render and export wavetables in the WAV format. It's free to use, privacy friendly, and you can just use it directly by going to https://carvetoy.online.
You can find a lot of experimental modules (generators, effects, combining effects a.k.a. combiners) to play with (all puns intended
).It also features a library of publicly shared wavetables that you can use in your own music production and sound design. And if you are curious enough, you can click on the "edit" button on every shared wavetable, you can edit the project, or just learn how it was made.
If you happen to create something interesting, you can share it on the site under the CC0 public domain license for others to use. Of course, you can just download the WAV file and make it your own. All the rendering is actually performed in-browser, so what you create remains on your PC or mobile device and its yours forever.
Have fun experimenting
!ps,
there are already a few tutorial /demo videos on YouTube, which you can find here https://mastodon.social/@carvetoy.
