Sign every bounce, automatically.
AU / VST3 / CLAP — works in Logic, Ableton, FL Studio, Cubase, Reaper, and Pro Tools. Drop it on your master bus, bounce like you always do. We sign every export in the background with zero latency.
Free to install · Pro $10/mo unlocks signing. The plugin passes audio through unchanged on Free.
How it works
- 1
Bounce like you always do.
Drop the plugin on your master bus. Your offline- render behaviour doesn't change — no added latency, no altered audio, no workflow surgery.
- 2
We sign inline, zero-latency.
The plugin passes audio through unchanged while it fingerprints the bounce in the background. The signed record is written to your Projects the moment the render finishes.
- 3
View it in Projects.
Every signed bounce appears within ~200 ms of finishing. Add collaborators, share the ownership record, track unauthorised redistributions.
Install
Ships as a .pkg. Double-click to install; use the Customize panel to untick plugin formats you don't need (the helper is required). v1 is unsigned — Gatekeeper will warn "unknown developer". Right-click the .pkg and choose Open to approve (one-time prompt).
Ships as an MSI. Double-click to install; use the
feature-selection dialog to untick plugin formats you
don't need (the helper is required). Installs VST3 to
%COMMONPROGRAMFILES%\VST3 and CLAP to
%COMMONPROGRAMFILES%\CLAP, registers the
helper as a per-user Scheduled Task at logon. Restart
your DAW after install. v1 is unsigned — SmartScreen
will warn "unknown publisher"; click More info → Run
anyway.
Troubleshooting
Plugin doesn't show up in my DAW
Scan your plugin directory — most DAWs cache the plugin index. In Ableton: Preferences → Plug-ins → Rescan. In Logic: Preferences → Plug-in Manager → Reset & Rescan. In FL Studio: Options → Manage plugins → Find more plugins.
How does it sign during offline bounce?
Offline rendering runs faster than realtime in most DAWs. The plugin buffers the render in-process, fingerprints it after the host signals end-of-render, and uploads the fingerprint + metadata to your account. The audio file itself is never uploaded — only a compact acoustic fingerprint (~1 KB per minute).
Does it add latency to my session?
No. setLatencySamples(0) is hard-coded.
The plugin is a true passthrough during realtime
playback — fingerprinting happens on a side chain,
never in the audio path.
Can I revoke a plugin install?
Yes. Open your Account page and scroll to "Connected plugins" — each install is listed with its hostname and first-seen date, and can be revoked individually. Revoked installs can't sign new bounces but existing signed files stay valid.
What's the difference versus signing on the web?
The web uploader signs a finished audio file you drop in. The plugin signs every bounce you do inside your DAW, automatically, without leaving your session. Same cryptography, different ergonomics — plugin is right for production workflows, web is right for one-offs and files from other people.
