Stop letting meeting apps ruin your mix.
Synchain Bridge sends your DAW's project audio straight into Synchain Creative Space in the browser — no noise suppression, no echo cancellation, no automatic gain. Your collaborators hear exactly what you dialled in.

02Why
Meeting apps are built for talking.
Noise suppression, echo cancellation and automatic gain make voices clearer — and treat music as noise. Reverb tails get cut, the backing track dips in chunks, dynamics flatten out. In Synchain Creative Space, none of this is your problem anymore.
Meeting app
An audio path tuned for speech
Synchain Bridge
The original waveform, untouched
03Signal path
A path built for music alone.
No virtual audio cable, no patching. The plugin sends audio block by block at your DAW's buffer size and reports zero added latency to the host.

Your project
On the master bus or any stereo track. Your DAW's sound passes through untouched.

04Plugin
This is Synchain Bridge.
The whole plugin is one panel: status, meters, stream volume, Start.
- Status and clientsOffline, waiting or online — and how many browsers are connected.
- L / R metersLive levels of the streamed copy, with peak hold.
- Sample rate · channels · bufferFollows your DAW. Buffer is the length of one audio block, not end-to-end latency.
- Local port9420 by default; if it's taken, the plugin picks a free port between 9420 and 9429.
- Master volume0–200%, applied to the streamed copy only. Your DAW's sound is left alone.
- Start BridgeOne click starts the local server so the browser can connect.

05Room
Listeners download nothing.
Accounts, projects and who gets to listen all live in the browser. Once Synchain Creative Space connects to the plugin, turn on Broadcast to Room and everyone in the room hears your DAW.
- Only project admins and members can join the room; observers can view only.
- Your microphone takes a separate path, with its own choice of noise suppression.
- One way: DAW → room.

09FAQ
Questions.
How is this different from sending music over Zoom or Discord?
Voice-meeting apps tune their audio path for speech: noise suppression, echo cancellation and automatic gain treat music as noise, so it arrives muffled, smeared and pumping. Synchain Bridge sends DAW audio around that entire chain straight into the Synchain Creative Space room, while your microphone takes a separate path.
Do I sign in inside the plugin?
No. The plugin has no account and no project picker. Your account, projects and rooms live in Synchain Creative Space in the browser; the plugin only carries your DAW's sound to this computer. You need a Synchain account and to be an admin or member of the project.
Does it add latency?
The plugin reports zero added latency to the host and sends audio block by block at your DAW's buffer size, without stockpiling it. The Buffer reading on the panel is the length of one block, not end-to-end latency; what people in the room hear also depends on the network.
Is there any quality loss?
The plugin-to-browser hop stays on your computer as 32-bit float PCM — lossless. Into the room, audio is streamed as stereo Opus at 510 kbps by default, adjustable from 192 to 510 kbps.
Why can't Safari connect?
Safari blocks HTTPS pages from reaching ws://127.0.0.1, so on a Mac it can't see the plugin. Open Synchain Creative Space in Chrome, Edge or Firefox, and choose Allow when the browser asks about accessing other apps and services on this device.
Will it change the sound in my DAW?
No. Your DAW's audio passes through the plugin untouched; the plugin's master volume only applies to the copy that gets streamed.
Does it cost anything?
It's free during the beta. The plugin is open source under GPL-3.0-or-later, with the source on GitHub.
Install and connection details are on the download and install page; for anything else, see the FAQ.
