Browser Audio Bridge

WebRTC-to-Virtual-Device Audio Routing Tool

Headline outcome
“Built a practical bridge for feeding one browser session’s audio into another through an OS-level virtual device.”
Business Outcome: Bridged browser tab audio inputs to secondary windows via WebRTC and OS-level virtual sound devices.

Why it matters

Solved a real browser limitation by combining WebRTC delivery with OS-level audio device routing.

Current signal

Backup

Focused delivery from architecture through working interaction model.

Mission

Why this system had to exist

This tool came from a very specific systems problem: browsers do not allow one site to inject microphone audio directly into another tab, even when the workflow clearly needs it. I needed a local utility that could take audio from one browser context and make it available to another in a standards-compliant way.

Active layer

Tab Audio Capture

Captures shared browser-tab audio and relays it to a second session

This layer participates in the wider system boundary described in the story above, connecting runtime behavior, user-facing interaction, and safety constraints into one deployable stack.

Before / after transformation

The outcome is easier to feel when you switch between baseline and optimized states.

Before

Audio Routing

Manual fragile workarounds

After

Optimized resolution

Structured bridge flow

What shipped

Captures shared browser-tab audio and relays it to a second session

Supports virtual sink creation for Linux audio routing

Lets downstream browser tools consume routed audio as microphone input

Works even when automatic sink creation is unavailable
