WhatsApp recently launched MLow codec to improve call reliability. Existing codecs, like Opus, struggle to maintain audio quality at low bitrates, leading to unclear and unnatural sound. Newer AI-based codecs offer better quality but are too computationally expensive for many users. MLow is designed to be computationally efficient while still delivering high-quality audio at low bitrates. It has shown significant improvement over Opus in tests, especially at the lowest bitrates. MLow has already been launched for Instagram and Messenger calls, with a rollout on WhatsApp underway. Future work will focus on improving audio recovery in challenging network conditions.
