FAQ

Common questions

What does SpectraBridge do?

SpectraBridge turns any macOS window, application or full display into a live Syphon video source — low-latency, GPU-accelerated desktop capture for live production, streaming and visuals.

Does SpectraBridge work on Apple Silicon?

Yes — it is a native macOS application optimised for Apple Silicon and Intel Macs.

What can I capture?

Your entire desktop, a specific application, or an individual window — published as a standard Syphon server that any Syphon-compatible app (Resolume, MadMapper, VDMX, OBS Studio, TouchDesigner and more) can receive instantly.

Why not just use OBS Studio?

OBS is a streaming and recording tool, and its Syphon support is plugin-dependent and can be fragile under show conditions. SpectraBridge is a focused, reliable window-to-Syphon bridge with minimal CPU overhead — built specifically for live production.

Is there a free trial?

Yes — a 7-day free trial (watermarked output) before purchase.
