December 2022 Summaries

The world has become louder, causing disruptions in meetings and affecting the quality of audio and video tracks. Businesses are seeking solutions to reduce noise and improve sound quality. Agora offers acoustic noise reduction technology to enhance communication for working professionals. This article will discuss what noise reduction is and how Agora implements it to improve business communication.

The article discusses the importance of software for echo cancellation in enhancing real-time communication quality. Echoes can significantly degrade call quality and increase bandwidth usage due to additional sound information. Two key methods exist for handling echo - echo cancellation and echo suppression. Echo cancellers estimate the echo path from the transmitting end to the receiving end, while echo suppressors mitigate and eliminate echo during calls. The article also provides natural ways of minimizing echoes such as using microphones with narrow pickup direction, reducing microphone volume, investing in acoustic foam or switching to noise-canceling headphones. Agora's RTC SDK offers automatic echo cancellation for high-quality calls and supports advanced features like AI noise suppression and Bose PinPoint noise filtering.
