audio improvements

Meta has released a comprehensive update for Facebook Messenger, introducing several new features aimed at enhancing user experience. Key updates include the introduction of AI Backgrounds for video calls, allowing users to customize their environments with prompts or pre-made options. Improvements have also been made to audio and video call quality, including HD quality, advanced noise suppression, and voice isolation. Users can now leave audio or video messages for unanswered calls and use Siri for hands-free call initiation. Additionally, Messenger now has default end-to-end encryption for enhanced security, the ability to edit sent messages, and the introduction of a dedicated chatbot powered by Meta AI.
