Energy charge

Hold to build energy. Shape the sound with progress.

Independent catalog source you own. recipe.ts, progress.ts, host.ts, index.html.

Charge: stopped

Hold with a pointer, touch, Space, or Enter. Three seconds to full charge. Release keeps the tail. Stop cuts it. Rings follow charge, including while muted.

Default implementation. Using the demo does not change these files.

Copy the sound.

recipe.ts is independent copy-in source. It belongs to your application. Install audiobits, copy this file, and create the sound with audio.sound(energyCharge). From a user gesture, start audio, play the sound, then update charge on that voice and stop it.

audio.sound(energyCharge) then voice.set({ charge }) and voice.stop().

Sustained energy field. Schema-1 data with a live charge parameter. Independent copy-in source you own.
