Why Interactive Live Streaming

When people feel engaged in an experience, they stay longer.

Large-scale events can be especially difficult to personalize, but Agora’s interactive live streaming SDKs make it easy for you to build apps with live audio and interactive video streaming that encourage real-time exchanges, creating deeper connections and driving revenue opportunities.

Only pay for the audio and video you use

Don’t let your audience feel alone in the crowd.

Connect them in real time to each other and to presenters with text messaging, virtual gifts, sounds, emojis, audience promotion to speaker, and much more.


A premium experience for a select audience.

Agora’s Interactive Live Streaming Premium keeps audiences engaged at ultra-low latency (400 – 800 ms), and is perfect for use cases like these:

Talk Show

A premium audience enjoys real-time interaction with minimal latency during the show, while the viewing audience has higher latency but more affordable access.

Sports Broadcast

A broadcast host has a premium group of sports analysts ready to step up when called on to share their play-by-play insights.

Live Auction

Exclusive online bidders act fast with ultra-low latency premium streaming, while the viewing audience watches with cost-effective standard streaming.

For any use case where, ultra-low latency is not required, we offer Interactive Live Streaming Standard with low latency (1,500 – 2,000 ms).  


The control is in your hands.

We make it easy for you to customize all aspects of the audio and streaming experience, including controlling latency at the flip of one parameter.

CDN allows you to reach large audiences but with a long latency. Agora’s live video streaming API can reach the same large, global audiences with much lower latency, opening a world of richly interactive in-app experiences.


Everything you need for a superior interactive streaming experience.

Outstanding audio

Full bandwidth capture

A 48kHz (sampling rate) full-sound bandwidth capture provides the most natural audio reproduction where audio quality is of critical importance. Stream audio up to 192kbps to reproduce the original audio source in high fidelity.

3D spatial audio

With Agora’s 3D Spatial Audio, proximity-based sensing is used to determine if a speaker is closer or farther away within a virtual room, making it a more In Real Life (IRL) experience for participants.

Fast initial rendering and channel switching

Agora’s sub-second initial audio rendering and channel-switching time creates a seamless live-video streaming experience for listeners.

Adaptive bitrate

Select an audio profile with a bitrate of 18kbps to 192kbps to provide the appropriate quality for your content needs.

Smooth experience

Agora’s sophisticated streaming network algorithms minimize latency and packet loss for smooth, stutter-free, live streaming without interruptions.

Voice effects

Make voice calls fun and engaging with a range of voice effects. From audio mixing to reverb, your users will spend more time in chat experimenting with all the possibilities.

High quality video streaming

HD experience

High-definition video up to 1080p cross-platform is mobile-friendly with 1080p and 30fps (hardware limitations apply). Agora provides in-house video codec support for superior compression and image quality for optimal real-time video streaming.

Fast channel switching

Agora’s sub-second channel-switching time creates a seamless live video streaming viewing experience.

Fast rendering

Agora’s fast initial frame rendering and channel creation delivers real-time, seamless video.

Adaptive bitrate

Agora’s patented smart encoder/decoder algorithm delivers the best resolution based on each user’s hardware and network bandwidth.


Agora’s perception-based encoding algorithm reduces the video bitrate and bandwidth required without sacrificing video quality.

Dual video live streams

When you’re serving a large audience with mixed devices and network bandwidth conditions, take advantage of Agora’s optional dual-video streaming to deliver video at both high and low bitrates.
