AI BriefingSystem Audio Feature Introduced
Key point
Replit has introduced an opt-in system audio integration feature that can be used in the VNC environment.
Details
Replit has introduced system audio integration as an opt-in feature to enhance the creativity and fun of programming.
Considering resource consumption, this feature must be activated directly by the user. The activation method is as follows.
- Create a Secret named
VNC_ENABLE_EXPERIMENTAL_AUDIOand set its value to1. - Run the
kill 1command in the shell to restart the repl. - Once set up, a headphone icon will appear in the bottom right corner of the VNC output window.
Technically, Replit built a new solution to deliver PulseAudio's compressed audio together with the Remote Framebuffer (RFB) protocol. To solve bandwidth issues and improve maintenance efficiency, Replit developed rfbproxy, written in Rust.
rfbproxy connects to XtigerVNC and PulseAudio, transcodes the audio into an Opus stream and WebM container, and delivers it as an RFB stream integrated into the NoVNC client.
