7## Reuse Single AudioContext
8 
9Reuse a single AudioContext instance; do not create new ones per sound.
10 
11**Incorrect (new context per call):**
12 
13```ts
14function playSound() {
15  const ctx = new AudioContext();
16}
17```
18 
19**Correct (singleton):**
20 
21```ts
22let audioContext: AudioContext | null = null;
23 
24function getAudioContext(): AudioContext {
25  if (!audioContext) {
26    audioContext = new AudioContext();
27  }
28  return audioContext;
29}
