Interactive Live Audio & Video Streaming SDK
Host large-scale live audio and video streaming events with real-time interactivity using Agora’s Interactive Live Streaming API.
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 audio and video streaming that encourage real-time exchanges, creating deeper connections and driving revenue opportunities.
Interactive streaming at very large scale
Excellent synchronization between end points
Seamlessly promote audience members to speak
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.
INTERACTIVE LIVE STREAMING PREMIUM
A premium experience for a select audience.
Agora’s Interactive Live Streaming keeps audiences engaged at low latency (1,500 – 2,000 ms). For your use cases that target smaller, more exclusive audiences and require ultra-low latency (400 – 800 ms), consider Interactive Live Streaming Premium.
Premium is perfect for select audiences in scenarios 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.
BUILT FOR DEVELOPERS
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.
Features
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.
3-D spatial audio
With Agora’s 3-D 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

Adaptive bitrate
Agora’s patented smart encoder/decoder algorithm delivers the best resolution based on each user’s hardware and network bandwidth.
Efficiency
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.
Flexibility
Cross-channel co-hosting

Screen sharing
While streaming live video, participants can share their entire screen, a specific area or a single tab.
AI-powered services
AI-powered add-on services
Use Agora’s live video streaming APIs to integrate AI-powered services such as AR facial masks, facial beautification, and more.
