Sender-Side Option! (&push)

Aliases

• &isolation

• &vi

Options

Examples:

• &voiceisolation (enable)

• &voiceisolation=true

• &voiceisolation=0 or &voiceisolation=off (disable)

Details

• Capture constraint: requests getUserMedia({ audio: { voiceIsolation: true } }).

• Scope: microphone capture only. It is not applied to getDisplayMedia() screen-share / tab / system-audio capture paths.

• Goal: reduce background noise and prioritize speech at the OS/browser level.

• Support varies; commonly available on iOS/macOS Safari. Unsupported browsers will ignore the flag.

• Interactions: can be used alongside echo cancellation, auto-gain, and noise suppression. Actual behavior may differ by platform.

• Performance: on slower or already CPU-bound guests, &voiceisolation can increase processing load and contribute to lag.

• Workarounds: if guests start falling behind, try &noap to disable the extra Web Audio processing pipeline, or use &denoise instead when you want a lighter noise-reduction option.
