Real-time audio at Meta scale

The talk will cover what goes into delivering a reliable and high quality audio experience that scales across the diversity of device and network conditions of our users across Meta’s family of apps including Messenger, Instagram, Facebook and WhatsApp. In addition to covering components such as gain control, echo cancellation, noise suppression and codecs that are typically spoken about, the talk will dive deep into a less familiar but arguably more important problem of audio reliability (can you hear me?). The talk will also address new challenges in delivering audio for the Metaverse where users experience the magic of being present in the same room.
