The Agora Native SDK for Audio Broadcasting enables one-to-many and many-to-many audio live streaming. Different from the traditional CDN live broadcast, which only allows one-way communication from the hosts to the audience, the Agora SDK for Interactive Broadcast empowers the audience to interact with the hosts through hosting-in, like a viewer jumping onto the stage in the middle of a play to perform. The Agora Native SDK for Interactive Broadcast is applicable to scenarios that encourage active engagement, such as game-playing, online classes for students in small groups, and Q&A sessions during E-commerce live streaming.
