Function adsrIterable

Creates and runs an envelope, sampling its values at sampleRateMs. Note that if the envelope loops, iterator never returns.

Example: Init

import { Envelopes } from 'https://unpkg.com/ixfx/dist/modulation.js';
import { IterableAsync } from  'https://unpkg.com/ixfx/dist/util.js';

const opts = {
 attackDuration: 1000,
 releaseDuration: 1000,
 sustainLevel: 1,
 attackBend: 1,
 decayBend: -1
};
Copy

//  Add data to array
// Sample an envelope every 20ms into an array
const data = await IterableAsync.toArray(Envelopes.adsrIterable(opts, 20));
Copy

// Iterate with `for await`
// Work with values as sampled
for await (const v of Envelopes.adsrIterable(opts, 5)) {
 // Work with envelope value `v`...
}
Copy
