RCS Messaging Gains Major Audio Quality Boost with Universal Profile 3.1 Update

The latest iteration of the Universal Profile (v3.1) for RCS messaging is set to revolutionize voice messages and shared audio clips with significantly improved sound quality. Announced by the GSMA, this update introduces the advanced xHE-AAC audio codec, enabling highly efficient compression and decompression of audio content.
Users can anticipate clearer, more natural playback for voice notes, ambient sound clips, and even audio-based chatbot interactions. This enhancement is expected to provide a more immersive and reliable audio experience within RCS applications.
Beyond audio improvements, Universal Profile 3.1 also brings several other key advancements, including new mechanisms to streamline the connection between RCS clients and operator services, promising a more seamless user onboarding process. Additionally, the update features better spam reporting capabilities, enhanced file transfer security, and the integration of deep links for initiating conversations.
These changes will gradually roll out as RCS applications, such as Google Messages, adopt the new standard, promising a more robust and feature-rich messaging experience for users worldwide.
