Official documentation guide
Can a Chrome site start microphone recording while another tab is active?
Short answer
Chrome limits when sites can begin recording. Permission alone does not mean a background site may silently start microphone capture; the active-site and browser controls still apply.
What the documentation establishes
- Site permission is only one part of Chrome microphone access.
- Chrome restricts microphone use when a site is not active.
Scope and limits
Documentation synthesis; no hands-on testing was performed. Behavior can change with software version, language, permissions, focus, device, and application configuration.
