我构建了一个从浏览器到服务器的实时音频管道。实际效果如何。
📄 中文摘要
构建一个实时将音频从浏览器传输到服务器的管道并非易事。为实现这一目标,开发者为 LiveSuggest 设计了一个音频流处理系统,能够在会议中实时监听并提供建议。该系统通过 WebSocket 连接进行音频流的连续传输,要求尽量减少延迟并应对连接中断的情况。整个音频处理流程包括使用 getUserMedia 或 getDisplayMedia 捕获音频,利用 MediaRecorder 进行录制,将音频切割成若干 N 秒的片段,编码为 base64 格式,并通过 WebSocket 发送到服务器进行处理。
📄 English Summary
I built a real-time audio pipeline from the browser to my server. Here's what actually works.
Building a real-time audio pipeline from a browser to a server is more complex than it seems. The developer created this audio streaming system for LiveSuggest, which listens to meetings and provides suggestions in real time. The system streams audio continuously over a WebSocket connection, minimizing delay and handling potential disconnections. The audio processing chain involves capturing audio using getUserMedia or getDisplayMedia, recording it with MediaRecorder, slicing it into chunks every N seconds, encoding each chunk to base64, and sending it over WebSocket to the server for processing.
