Adding chat and video to a web app

The first video path used a direct browser peer connection, with signaling stored in the app and an empty ICE server list so media would not pass through a relay. The script was syntax-checked and reviewed for glare handling. No browser was available, so no call was placed. A hosted video SDK later replaced this path.

What worked
A direct peer connection keeps audio and video off a recording service. The page script parsed cleanly and did not use a recording API.
What got in the way
With no ICE servers, peers on different networks have no STUN or relay path. Glare, role switch, and queued ICE candidates took several manual passes. A real peer connection was never opened.

Streaming two-way audio in a phone browser

Browser WebRTC APIs were used for microphone audio, remote playback, session negotiation, a control data channel, and native interruption behavior. The implementation and build succeeded, but no live browser call was exercised.

What worked
The peer-connection model enabled direct low-latency browser media while keeping the service credential on the server.
What got in the way
Runtime behavior across phone browsers and actual connection recovery could not be assessed without a live API session.

Connecting browser audio directly to a realtime speech service

Implemented browser microphone capture, peer-connection audio, and data-channel event handling for low-latency two-way speech. The code compiled, but actual phone-browser media, barge-in, and network-recovery behavior could not be exercised without service credentials.

What worked
The API supported the required direct browser transport and separate event channel without introducing a custom media relay.
What got in the way
The record contains no live browser media session, so permission handling, mobile compatibility, and connection reliability were not assessed.

Streaming browser microphone audio to a realtime assistant

Integrated a WebRTC-based browser audio path through the Realtime SDK, including explicit start, mute, stop, and cleanup behavior. The application compiled, but no microphone-enabled browser session was run, so media reliability was not observed.

What worked
WebRTC fit the browser security model and enabled direct low-latency audio transport without exposing a permanent server credential.
What got in the way
Microphone permission behavior, device compatibility, connection recovery, and audio quality were not tested in a live browser.

Streaming microphone input and assistant audio in the browser

Implemented the browser-side WebRTC negotiation and media path for low-latency microphone input, assistant audio, interruption, and a data-channel event loop. The application built successfully, but the record contains no live browser session, so runtime reliability was not assessed.

What worked
The native browser API avoided an additional client SDK and fit the requirement for natural streaming audio and conversational interruption.
What got in the way
The asynchronous event and connection lifecycle required careful handling, including consideration of closure during connection and several possible event payload shapes.
