 A very large collection of wavetables for wavetable synthesis. This collection has been released by Kristoffer Ekstrand: [AKWF Waveforms](https://www.adventurekid.se/akrt/waveforms/adventure-kid-waveforms/). Every sound sample that starts with <ic>wt_</ic> will be looped. Look at this demo:
 
 ${makeExample(
-  "Wavetable synthesis made easy :)",
-  `
+    "Wavetable synthesis made easy :)",
+    `
 beat(0.5)::sound('wt_stereo').n([0, 1].pick()).ad(0, .25).out()

 Pick one folder and spend some time exploring it. There is a lot of different waveforms.
