Communications APIs
Voice Call
Dolby.io Communications APIs leverage the power of Dolby Voice® to create crystal-clear voice chat and calling for your browser, mobile, and PC apps. Enable spatial chat to create lifelike real-time audio scenes that benefit from audiovisual congruence.

Featuring Dolby Voice® Technology
Build your voice chat solution
Advanced spatial chat
Understand one another better even when users talk over each other. With spatial chat, overlapping voices are separated to make conversations sound natural — resulting in increased user productivity and reduced fatigue.
Customizable audio settings
Focus attention on the audio that matters most for your use case. Dolby.io lets developers decide what kind of audio makes it into a conference: voice, background effects, or music (with Music Mode).
Network resilience
Maintain high-quality audio in challenging network conditions with advanced network resilience that keeps communications running at all times.
Voice processing
Powered by machine learning, our voice activity detector, automatic gain control, and dynamic audio leveling detect when you’re speaking, remove background noise, keep unwanted sounds out, and maintain consistent levels between clients.
Mixing mode
Scale video conferencing with the Dolby Voice® codec to allow participants to hear everything — even at a low bitrate or on a single audio stream. The mixing solution processes more than 15B minutes annually with conference providers, including BlueJeans and British Telecom.
Integrated audio device management
Let us worry about devices. Our SDK automatically detects device characteristics, optimizes on-device audio capture and rendering, and as required, makes instantaneous audio adjustments to accommodate known device issues.
Secure, reliable, and scalable
We remove the complexity of building a communications solution while ensuring security and compliance, including access to a global infrastructure. Dolby.io is GDPR, HIPAA, and SOC-2 compliant.
Conference metadata and statistics
Learn more about the experience of your customers by using our Monitor API. This REST endpoint provides statistics, identifies when participants talk, can help debug connectivity issues, track usage and retrieve recordings.
Demo
Experience Dolby.io Spatial Chat

Experience voice and video calls like never before with Dolby.io Spatial Chat — now enhanced with manual Spatial Placement. The Spatial Placement feature enhancement allows developers to manually place sound objects anywhere within a three-dimensional space to create immersive audio scenes. Build high-fidelity, real-time communications and improve the listening experiences with less fatigue.
Demo
Experience Dolby.io Spatial Chat in the metaverse
Odyssey, an immersive metaverse platform, chose Dolby.io Spatial Chat to give users in the metaverse freedom to move and talk with a high-fidelity experience — like when meeting together in-person. For the full experience, try the demo on a laptop or desktop computer, use headphones, and grab a few friends to join the room.
