9Use filtered noise for clicks/taps, not oscillators.

11**Incorrect (oscillator for click):**
12 
13```ts
14const osc = ctx.createOscillator();
15osc.type = "sine";
16```
17 
18**Correct (noise burst for click):**
19 
20```ts
21const buffer = ctx.createBuffer(1, ctx.sampleRate * 0.008, ctx.sampleRate);
22const data = buffer.getChannelData(0);
23for (let i = 0; i < data.length; i++) {
24  data[i] = (Math.random() * 2 - 1) * Math.exp(-i / 50);
25}
26```
