Video and audio calling has become the go-to method for staying in touch with close ones as well as interacting with workplace colleagues. However, if you are one of the users who have slow internet connectivity, then it can actually become a frustrating experience because of issues like poor quality and random call drops. Google has now made an announcement about a new codec aimed at resolving these same issues.
Google has announced a new codec named Lyra which is currently under testing. This new codec will be used for improving Google Duo call quality. The codec will essentially result in high-quality audio performance despite running on slow internet connectivity. It makes use of AI-powered algorithms to deliver improved quality to users.
The official blog post says,
"To solve this problem, we have created Lyra, a high-quality, very low-bitrate speech codec that makes voice communication available even on the slowest networks. To do this, we’ve applied traditional codec techniques while leveraging advances in machine learning (ML) with models trained on thousands of hours of data to create a novel method for compressing and transmitting voice signals."
Lyra will offer an audio bitrate of 3kbps which is way lower than other commonly used codecs. It will eventually result in lower data consumption without affecting the audio quality. This new tech will work with the Google Duo application on both Android and iOS devices. An exact release timeline has not been revealed yet but it is likely to become available through a server-side change. We can expect Google to make another announcement once it is widely available.
