Real-Time Voice & Video
Updated
Build live audio, video, broadcast, and edge-device experiences on Agora's real-time media foundation.
Real-Time Audio & Video is the capability layer for products where live media is the primary user experience. This category covers two-way voice and video interaction, host-audience live experiences, large-scale broadcast delivery, and device-oriented real-time connectivity.
Agora's product map for this layer includes:
- Voice Calling
- Video Calling
- Interactive Live Streaming
- Fusion CDN broadcast delivery
- IoT / RTSA edge-device connectivity
What this category is good for
This category is the right entry point when you need:
- one-to-one or group voice and video calling
- meetings, classrooms, and telehealth sessions
- creator-led or host-audience live interaction
- broadcast-style delivery to larger audiences
- smart-device, camera, or edge-terminal media connectivity
The shared requirement is stable, low-latency media transport with clear session behavior across networks, devices, and participant roles.

Key characteristics
Shared media foundation
Use the same real-time transport model across calling, live interaction, broadcast expansion, and device connectivity.
Flexible interaction patterns
Support peer-to-peer, group, host-audience, and device-oriented topologies without switching to a different conceptual model.
Scale from interaction to distribution
Start from interactive sessions, then extend into larger audience delivery or downstream cloud media services.
Cross-device coverage
Reach web, mobile, desktop, and edge-device products with consistent session and media semantics.
Works with adjacent layers
Combine media transport with messaging, AI, transcription, recording, and analytics as product requirements grow.
Network resilience
Keep the live experience usable under real-world packet loss, geography, and device constraints.
