Screen Share Coordinator
A simulated screen-share/recording app that handles the Chrome 136 interrupted AudioContext state. When the OS interrupts audio focus (phone call, notification), the app stops recording, saves progress, shows an "interrupted by system" banner, and resumes cleanly when focus returns — distinguishing system interruption from user pause.

Chrome 136 adds
AudioContextState.interrupted. Without this state, apps had no way to distinguish "user paused" from "OS took audio focus away". With it, you can show the right UI ("paused by system" vs "you paused") and auto-resume only when it's safe to do so.

Interrupt handler pattern
// Chrome 136: handle the new 'interrupted' state
const ctx = new AudioContext();
ctx.addEventListener('statechange', () => {
switch (ctx.state) {
case 'running':
// Normal operation — recording active
resumeRecording();
hideInterruptBanner();
break;
case 'interrupted':
// OS took audio focus (phone call, notification, system alert)
// Different from 'suspended' which is user/tab-triggered
pauseRecording({ reason: 'system-interrupt' });
showBanner('Audio interrupted by system — recording paused');
// DO auto-resume when state goes back to 'running'
break;
case 'suspended':
// User or browser suspended — do NOT auto-resume
pauseRecording({ reason: 'user-suspended' });
break;
case 'closed':
stopRecording();
break;
}
});
