setEchoCancellation

1
setEchoCancellation(enabled): Promise<void>

Toggle echo cancellation on the local mic at runtime. Applied via track.applyConstraints; browsers that don’t honour runtime constraints (notably iOS Safari) fall back to re-acquiring the track with the new constraint set and plumbing the replacement through the local audio pipeline if one is active.

Parameters

Returns

Promise<void> — resolves after the constraint has been applied (via applyConstraints or, on browsers without runtime support, after a track replacement).

Examples

Toggle from a UI switch

1
echoSwitch.addEventListener('change', async (e) => {
2
  await call.setEchoCancellation(e.target.checked);
3
});
