Agora Live Interactive Audio Streaming enables one-to-many and many-to-many audio live streaming with the Agora RTC SDK.
Agora Live Interactive Audio Streaming is different from Agora Voice Call. In a voice call, all users are the same role and can talk to each other freely. In a live audio streaming, users can be the host or audience, where only the host can talk. For details, see this FAQ.
Different from the traditional CDN live streaming, which only allows one-way communication from the hosts to the audience, the Agora SDK for interactive live streaming empowers the audience to interact with the hosts by becoming a host, like a viewer jumping onto the stage in the middle of a play to perform.
Agora Live Interactive Audio Streaming 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.
Agora Live Interactive Audio Streaming boasts a flexible combination of functions for different scenarios.
